Guide to the Secure Configuration of Red Hat Enterprise Linux CoreOS 4

with profile NIST National Checklist for Red Hat Enterprise Linux CoreOS
This compliance profile reflects the core set of security related configuration settings for deployment of Red Hat Enterprise Linux CoreOS into U.S. Defense, Intelligence, and Civilian agencies. Development partners and sponsors include the U.S. National Institute of Standards and Technology (NIST), U.S. Department of Defense, the National Security Agency, and Red Hat. This baseline implements configuration requirements from the following sources: - Committee on National Security Systems Instruction No. 1253 (CNSSI 1253) - NIST Controlled Unclassified Information (NIST 800-171) - NIST 800-53 control selections for Moderate-Impact systems (NIST 800-53) - U.S. Government Configuration Baseline (USGCB) - NIAP Protection Profile for General Purpose Operating Systems v4.2.1 (OSPP v4.2.1) - DISA Operating System Security Requirements Guide (OS SRG) For any differing configuration requirements, e.g. password lengths, the stricter security setting was chosen. Security Requirement Traceability Guides (RTMs) and sample System Security Configuration Guides are provided via the scap-security-guide-docs package. This profile reflects U.S. Government consensus content and is developed through the ComplianceAsCode initiative, championed by the National Security Agency. Except for differences in formatting to accommodate publishing processes, this profile mirrors ComplianceAsCode content as minor divergences, such as bugfixes, work through the consensus and release processes.
The SCAP Security Guide Project

This guide presents a catalog of security-relevant configuration settings for Red Hat Enterprise Linux CoreOS 4. It is a rendering of content structured in the eXtensible Configuration Checklist Description Format (XCCDF) in order to support security automation. The SCAP content is is available in the scap-security-guide package which is developed at https://www.open-scap.org/security-policies/scap-security-guide.

Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.
Do not attempt to implement any of the settings in this guide without first testing them in a non-operational environment. The creators of this guidance assume no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic.

Checklist

Group   Guide to the Secure Configuration of Red Hat Enterprise Linux CoreOS 4   Group contains 52 groups and 226 rules
Group   System Settings   Group contains 44 groups and 211 rules
[ref]   Contains rules that check correct system settings.
Group   Installing and Maintaining Software   Group contains 6 groups and 8 rules
[ref]   The following sections contain information on security-relevant choices during the initial operating system installation process and the setup of software updates.
Group   System and Software Integrity   Group contains 4 groups and 7 rules
[ref]   System and software integrity can be gained by installing antivirus, increasing system encryption strength with FIPS, verifying installed software, enabling SELinux, installing an Intrusion Prevention System, etc. However, installing or enabling integrity checking tools cannot prevent intrusions, but they can detect that an intrusion may have occurred. Requirements for integrity checking may be highly dependent on the environment in which the system will be used. Snapshot-based approaches such as AIDE may induce considerable overhead in the presence of frequent software updates.
Group   Software Integrity Checking   Group contains 1 group and 1 rule
[ref]   Both the AIDE (Advanced Intrusion Detection Environment) software and the RPM package management system provide mechanisms for verifying the integrity of installed software. AIDE uses snapshots of file metadata (such as hashes) and compares these to current system files in order to detect changes.

The RPM package management system can conduct integrity checks by comparing information in its metadata database with files installed on the system.
Group   Verify Integrity with AIDE   Group contains 1 rule
[ref]   AIDE conducts integrity checks by comparing information about files with previously-gathered information. Ideally, the AIDE database is created immediately after initial system configuration, and then again after any software update. AIDE is highly configurable, with further configuration information located in /usr/share/doc/aide-VERSION.

Rule   Install AIDE   [ref]

The aide package can be installed with the following command: 
Rationale:
The AIDE package must be installed if it is to be available for integrity checking.

                Federal Information Processing Standard (FIPS)
                          Group contains  1 rule
[ref]  
                        The Federal Information Processing Standard (FIPS) is a computer security standard which
is developed by the U.S. Government and industry working groups to validate the quality
of cryptographic modules. The FIPS standard provides four security levels to ensure
adequate coverage of different industries, implementation of cryptographic modules, and
organizational sizes and requirements.



FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules
utilize authentication that meets industry and government requirements. For government systems, this allows
Security Levels 1, 2, 3, or 4 for use on Red Hat Enterprise Linux CoreOS 4.



See http://csrc.nist.gov/publications/PubsFIPS.html for more information.
Rule  
                                Enable FIPS Mode
                                  [ref]
To enable FIPS mode, run the following command:

fips-mode-setup --enable



The fips-mode-setup command will configure the system in
FIPS mode by automatically configuring the following:

  • Setting the kernel FIPS mode flag (/proc/sys/crypto/fips_enabled) to 1
  • Creating /etc/system-fips
  • Setting the system crypto policy in /etc/crypto-policies/config to FIPS
  • Loading the Dracut fips module

Furthermore, the system running in FIPS mode should be FIPS certified by NIST.
Warning: 
                                        The system needs to be rebooted for these changes to take effect.
Warning: 
                                        System Crypto Modules must be provided by a vendor that undergoes
FIPS-140 certifications.
FIPS-140 is applicable to all Federal agencies that use
cryptographic-based security systems to protect sensitive information
in computer and telecommunication systems (including voice systems) as
defined in Section 5131 of the Information Technology Management Reform
Act of 1996, Public Law 104-106. This standard shall be used in
designing and implementing cryptographic modules that Federal
departments and agencies operate or are operated for them under
contract. See https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf
To meet this, the system has to have cryptographic software provided by
a vendor that has undergone this certification. This means providing
documentation, test results, design information, and independent third
party review by an accredited lab. While open source software is
capable of meeting this, it does not meet FIPS-140 unless the vendor
submits to this process.
Rationale:
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to
protect data. The operating system must implement cryptographic modules adhering to the higher
standards approved by the federal government since this provides assurance they have been tested
and validated.

                System Cryptographic Policies
                          Group contains 5 rules
[ref]  
                        Linux has the capability to centrally configure cryptographic polices. The command
update-crypto-policies is used to set the policy applicable for the various
cryptographic back-ends, such as SSL/TLS libraries. The configured cryptographic
policies will be the default policy used by these backends unless the application
user configures them otherwise. When the system has been configured to use the
centralized cryptographic policies, the administrator is assured that any application
that utilizes the supported backends will follow a policy that adheres to the
configured profile.

Currently the supported backends are:

  • GnuTLS library
  • OpenSSL library
  • NSS library
  • OpenJDK
  • Libkrb5
  • BIND
  • OpenSSH

Applications and languages which rely on any of these backends will follow the
system policies as well. Examples are apache httpd, nginx, php, and others.
Rule  
                                Configure System Cryptography Policy
                                  [ref]
To configure the system cryptography policy to use ciphers only from the FIPS
policy, create a MachineConfig as follows:

---
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
  labels:
    machineconfiguration.openshift.io/role: master
  name: 50-master-configure-crypto-policy
spec:
  config:
    ignition:
      version: 3.1.0
    systemd:
      units:
        - name: configure-crypto-policy.service
          enabled: true
          contents: |
            [Unit]
            Before=kubelet.service
            [Service]
            Type=oneshot
            ExecStart=update-crypto-policies --set FIPS
            RemainAfterExit=yes
            [Install]
            WantedBy=multi-user.target




This will configure the crypto policy appropriately in all the
nodes labeled with the "master" role.




Note that this needs to be done for each MachineConfigPool




For more information on how to configure nodes with the Machine Config
Operator see
the relevant documentation.



The rule checks if settings for selected crypto policy are configured as expected. Configuration files in the /etc/crypto-policies/back-ends are either symlinks to correct files provided by Crypto-policies package or they are regular files in case crypto policy customizations are applied.
Crypto policies may be customized by crypto policy modules, in which case it is delimited from the base policy using a colon.

                                Configure Kerberos to use System Crypto Policy
                                  [ref]
Crypto Policies provide a centralized control over crypto algorithms usage of many packages.
Kerberos is supported by crypto policy, but it's configuration may be
set up to ignore it.
To check that Crypto Policies settings for Kerberos are configured correctly, examine that there is a symlink at
/etc/krb5.conf.d/crypto-policies targeting /etc/cypto-policies/back-ends/krb5.config.
If the symlink exists, kerberos is configured to use the system-wide crypto policy settings.
Rationale:
Overriding the system crypto policy makes the behavior of Kerberos violate expectations,
and makes system configuration more fragmented.

                                  [ref]
Crypto Policies provide a centralized control over crypto algorithms usage of many packages.
OpenSSL is supported by crypto policy, but the OpenSSL configuration may be
set up to ignore it.
To check that Crypto Policies settings are configured correctly, you have to examine the OpenSSL config file
available under /etc/pki/tls/openssl.cnf.
This file has the ini format, and it enables crypto policy support
if there is a [ crypto_policy ] section that contains the .include /etc/crypto-policies/back-ends/opensslcnf.config directive.
Rationale:
Overriding the system crypto policy makes the behavior of the Java runtime violates expectations,

                                Harden SSH client Crypto Policy
                                  [ref]
Crypto Policies are means of enforcing certain cryptographic settings for selected applications including OpenSSH client.
To override the system wide crypto policy for Openssh client, place a file in the /etc/ssh/ssh_config.d/ so that it is loaded before the 05-redhat.conf. In this case it is file named 02-ospp.conf containing parameters which need to be changed with respect to the crypto policy.
This rule checks if the file exists and if it contains required parameters and values which modify the Crypto Policy.
During the parsing process, as soon as Openssh client parses some configuration option and its value, it remembers it and ignores any subsequent overrides. The customization mechanism provided by crypto policies appends eventual customizations at the end of the system wide crypto policy. Therefore, if the crypto policy customization overrides some parameter which is already configured in the system wide crypto policy, the SSH client will not honor that customized parameter.
Rationale:
The Common Criteria requirements specify how certain parameters for OpenSSH Client are configured. Particular parameters are RekeyLimit, GSSAPIAuthentication, Ciphers, PubkeyAcceptedKeyTypes, MACs and KexAlgorithms. Currently particular requirements specified by CC are stricter compared to any existing Crypto Policy.

                                  [ref]
Crypto Policies are means of enforcing certain cryptographic settings for selected applications including OpenSSH server.
The SSHD service is by default configured to modify its configuration based on currently configured Crypto-Policy. However, in certain cases it might be needed to override the Crypto Policy specific to OpenSSH Server and leave rest of the Crypto Policy intact.
This can be done by dropping a file named opensshserver-xxx.config, replacing xxx with arbitrary identifier, into /etc/crypto-policies/local.d. This has to be followed by running update-crypto-policies so that changes are applied.
Changes are propagated into /etc/crypto-policies/back-ends/opensshserver.config. This rule checks if this file contains predefined CRYPTO_POLICY environment variable configured with predefined value.
Rationale:
The Common Criteria requirements specify that certain parameters for OpenSSH Server are configured e.g. supported ciphers, accepted host key algorithms, public key types, key exchange algorithms, HMACs and GSSAPI key exchange is disabled. Currently particular requirements specified by CC are stricter compared to any existing Crypto Policy.

                        In traditional Unix security, if an attacker gains
shell access to a certain login account, they can perform any action
or access any file to which that account has access. Therefore,
making it more difficult for unauthorized people to gain shell
access to accounts, particularly to privileged accounts, is a
necessary part of securing a system. This section introduces
mechanisms for restricting access to accounts under
Red Hat Enterprise Linux CoreOS 4.

[ref]  
                        Each system should expose as little information about
itself as possible.



System banners, which are typically displayed just before a
login prompt, give out information about the service or the host's
operating system. This might include the distribution name and the
system kernel version, and the particular version of a network
service. This information can assist intruders in gaining access to
the system as it can reveal whether the system is running
vulnerable software. Most network services can be configured to
limit what information is displayed.



Many organizations implement security policies that require a
system banner provide notice of the system's ownership, provide
warning to unauthorized users, and remind authorized users of their
consent to monitoring.

                                Modify the System Login Banner

To configure the system login banner edit /etc/issue. Replace the
default text with a message compliant with the local site policy or a legal
disclaimer.

[ref]  
                        It is impossible to fully protect a system from an
attacker with physical access, so securing the space in which the
system is located should be considered a necessary step. However,
there are some steps which, if taken, make it more difficult for an
attacker to quickly or undetectably modify a system from its
console.
Rule  
                                Disable debug-shell SystemD Service
                                  [ref]
SystemD's debug-shell service is intended to
diagnose SystemD related boot issues with various systemctl
commands. Once enabled and following a system reboot, the root shell
will be available on tty9 which is access by pressing
CTRL-ALT-F9. The debug-shell service should only be used
for SystemD related issues and should otherwise be disabled.



By default, the debug-shell SystemD service is already disabled.

The debug-shell service can be disabled with the following manifest:

---
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
  labels:
    machineconfiguration.openshift.io/role: master
  name: 75-master-debug-shell-disable
spec:

    ignition:
      version: 3.1.0
    systemd:
      units:
      - enabled: false
        name: debug-shell.service




This will disable the debug-shell service in all the
nodes labeled with the "master" role.




Note that this needs to be done for each MachineConfigPool




For more information on how to configure nodes with the Machine Config
Operator see
the relevant documentation.

Rationale:
This prevents attackers with physical access from trivially bypassing security
on the machine through valid troubleshooting configurations and gaining root
access when the system is rebooted.

                                  [ref]
By default, SystemD will reboot the system if the Ctrl-Alt-Del
key sequence is pressed Ctrl-Alt-Delete more than 7 times in 2 seconds.



To configure the system to ignore the CtrlAltDelBurstAction

setting, create a MachineConfig similar to the following:

apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
  labels:
    machineconfiguration.openshift.io/role: master
  name: 75-master-disable-ctrlaltdel-burstaction

        mode: 0644
        path: /etc/systemd/system.conf.d/disable_ctrlaltdelete_burstaction.conf
        overwrite: true
EOF




This will add the relevant configuration to /etc/systemd/system.conf.d/,
thus configuring Systemd apropriately.

Warning: 
                                        Disabling the Ctrl-Alt-Del key sequence
in /etc/init/control-alt-delete.conf DOES NOT disable the Ctrl-Alt-Del
key sequence if running in runlevel 6 (e.g. in GNOME, KDE, etc.)! The
Ctrl-Alt-Del key sequence will only be disabled if running in
the non-graphical runlevel 3.
Rationale:
A locally logged-in user who presses Ctrl-Alt-Del, when at the console,
can reboot the system. If accidentally pressed, as could happen in
the case of mixed OS environment, this can create the risk of short-term
loss of availability of systems due to unintentional reboot.

                                  [ref]
Red Hat Enterprise Linux CoreOS 4 systems support an "interactive boot" option that can
be used to prevent services from being started. On a Red Hat Enterprise Linux CoreOS 4
system, interactive boot can be enabled by providing a 1,
yes, true, or on value to the
systemd.confirm_spawn kernel argument in /etc/default/grub.
Remove any instance of 
systemd.confirm_spawn=(1|yes|true|on)
 from
the kernel arguments in that file to disable interactive boot. It is also
required to change the runtime configuration, run:

/sbin/grubby --update-kernel=ALL --remove-args="systemd.confirm_spawn"
Rationale:
Using interactive boot, the console user could disable auditing, firewalls,
or other services, weakening system security.

Single-user mode is intended as a system recovery
method, providing a single user root access to the system by
providing a boot option at startup. By default, no authentication
is performed if single-user mode is selected.



By default, single-user mode is protected by requiring a password and is set
in /usr/lib/systemd/system/rescue.service.
Rationale:
This prevents attackers with physical access from trivially bypassing security
on the machine and gaining root access. Such accesses are further prevented
by configuring the bootloader password.

Group  
                Protect Accounts by Restricting Password-Based Login
                          Group contains 2 groups and 5 rules
[ref]  
                        Conventionally, Unix shell accounts are accessed by
providing a username and password to a login program, which tests
these values for correctness using the /etc/passwd and
/etc/shadow files. Password-based login is vulnerable to
guessing of weak passwords, and to sniffing and man-in-the-middle
attacks against passwords entered over a network or at an insecure
console. Therefore, mechanisms for accessing accounts by entering
usernames and passwords should be restricted to those which are
operationally necessary.
Group  
                Verify Proper Storage and Existence of Password
Hashes
                          Group contains 2 rules
[ref]  
                        By default, password hashes for local accounts are stored
in the second field (colon-separated) in
/etc/shadow. This file should be readable only by
processes running with root credentials, preventing users from
casually accessing others' password hashes and attempting
to crack them.
However, it remains possible to misconfigure the system
and store password hashes
in world-readable files such as /etc/passwd, or
to even store passwords themselves in plaintext on the system.
Using system-provided tools for password change/creation
should allow administrators to avoid such misconfiguration.
Rule  
                                Prevent Login to Accounts With Empty Password
                                  [ref]
If an account is configured for password authentication
but does not have an assigned password, it may be possible to log
into the account without authentication. Remove any instances of the
nullok in

/etc/pam.d/system-auth

to prevent logins with empty passwords.
Note that this rule is not applicable for systems running within a
container. Having user with empty password within a container is not
considered a risk, because it should not be possible to directly login into
a container anyway.
Rationale:
If an account has an empty password, anyone could log in and
run commands with the privileges of that account. Accounts with
empty passwords should never be used in operational environments.

                Restrict Root Logins
                          Group contains 3 rules
[ref]  
                        Direct root logins should be allowed only for emergency use.
In normal situations, the administrator should access the system
via a unique unprivileged account, and then use su or sudo to execute
privileged commands. Discouraging administrators from accessing the
root account directly ensures an audit trail in organizations with
multiple administrators. Locking down the channels through which
root can connect directly also reduces opportunities for
password-guessing against the root account. The login program
uses the file /etc/securetty to determine which interfaces
should allow root logins.

The virtual devices /dev/console
and /dev/tty* represent the system consoles (accessible via
the Ctrl-Alt-F1 through Ctrl-Alt-F6 keyboard sequences on a default
installation). The default securetty file also contains /dev/vc/*.
These are likely to be deprecated in most environments, but may be retained
for compatibility. Root should also be prohibited from connecting
via network protocols. Other sections of this document
include guidance describing how to prevent root from logging in via SSH.
Rule  
                                Verify Only Root Has UID 0
                                  [ref]
If any account other than root has a UID of 0, this misconfiguration should
be investigated and the accounts other than root should be removed or have
their UID changed.


If the account is associated with system commands or applications the UID
should be changed to one greater than "0" but less than "1000."
Otherwise assign a UID greater than "1000" that has not already been
assigned.
Rationale:
An account has root authority if it has a UID of 0. Multiple accounts
with a UID of 0 afford more opportunity for potential intruders to
guess a password for a privileged account. Proper configuration of
sudo is recommended to afford multiple system administrators
access to root privileges in an accountable manner.

                                Direct root Logins Not Allowed
                                  [ref]
To further limit access to the root account, administrators
can disable root logins at the console by editing the /etc/securetty file.
This file lists all devices the root user is allowed to login to. If the file does
not exist at all, the root user can login through any communication device on the
system, whether via the console or via a raw network interface. This is dangerous
as user can login to the system as root via Telnet, which sends the password in
plain text over the network. By default, Red Hat Enterprise Linux CoreOS 4's
/etc/securetty file only allows the root user to login at the console
physically attached to the system. To prevent root from logging in, remove the
contents of this file. To prevent direct root logins, remove the contents of this
file by typing the following command:

$ sudo echo > /etc/securetty

Rationale:
Disabling direct root logins ensures proper accountability and multifactor
authentication to privileged accounts. Users will first login, then escalate
to privileged (root) access via su / sudo. This is required for FISMA Low
and FISMA Moderate systems.

                                Ensure that System Accounts Do Not Run a Shell Upon Login
                                  [ref]
Some accounts are not associated with a human user of the system, and exist to
perform some administrative function. Should an attacker be able to log into
these accounts, they should not be granted access to a shell.



The login shell for each local account is stored in the last field of each line
in /etc/passwd. System accounts are those user accounts with a user ID
less than UID_MIN, where value of UID_MIN directive is set in
/etc/login.defs configuration file. In the default configuration UID_MIN is set
to 1000, thus system accounts are those user accounts with a user ID less than
1000. The user ID is stored in the third field. If any system account
SYSACCT (other than root) has a login shell, disable it with the
command: 
$ sudo usermod -s /sbin/nologin SYSACCT
Warning: 
                                        Do not perform the steps in this section on the root account. Doing so might
cause the system to become inaccessible.
Rationale:
Ensuring shells are not given to system accounts upon login makes it more
difficult for attackers to make use of system accounts.

[ref]  
                        The audit service provides substantial capabilities
for recording system activities. By default, the service audits about
SELinux AVC denials and certain types of security-relevant events
such as system logins, account modifications, and authentication
events performed by programs such as sudo.
Under its default configuration, auditd has modest disk space
requirements, and should not noticeably impact system performance.



NOTE: The Linux Audit daemon auditd can be configured to use
the augenrules program to read audit rules files (*.rules)
located in /etc/audit/rules.d location and compile them to create
the resulting form of the /etc/audit/audit.rules configuration file
during the daemon startup (default configuration). Alternatively, the auditd
daemon can use the auditctl utility to read audit rules from the
/etc/audit/audit.rules configuration file during daemon startup,
and load them into the kernel. The expected behavior is configured via the
appropriate ExecStartPost directive setting in the
/usr/lib/systemd/system/auditd.service configuration file.
To instruct the auditd daemon to use the augenrules program
to read audit rules (default configuration), use the following setting:

 
ExecStartPost=-/sbin/augenrules --load

in the /usr/lib/systemd/system/auditd.service configuration file.
In order to instruct the auditd daemon to use the auditctl
utility to read audit rules, use the following setting:

 
ExecStartPost=-/sbin/auditctl -R /etc/audit/audit.rules

in the /usr/lib/systemd/system/auditd.service configuration file.
Refer to [Service] section of the /usr/lib/systemd/system/auditd.service
configuration file for further details.



Government networks often have substantial auditing
requirements and auditd can be configured to meet these
requirements.
Examining some example audit records demonstrates how the Linux audit system
satisfies common requirements.
The following example from Fedora Documentation available at
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/SELinux_Users_and_Administrators_Guide/sect-Security-Enhanced_Linux-Troubleshooting-Fixing_Problems.html#sect-Security-Enhanced_Linux-Fixing_Problems-Raw_Audit_Messages
shows the substantial amount of information captured in a
two typical "raw" audit messages, followed by a breakdown of the most important
fields. In this example the message is SELinux-related and reports an AVC
denial (and the associated system call) that occurred when the Apache HTTP
Server attempted to access the /var/www/html/file1 file (labeled with
the samba_share_t type):

type=AVC msg=audit(1226874073.147:96): avc:  denied  { getattr } for pid=2465 comm="httpd"
path="/var/www/html/file1" dev=dm-0 ino=284133 scontext=unconfined_u:system_r:httpd_t:s0
tcontext=unconfined_u:object_r:samba_share_t:s0 tclass=file

type=SYSCALL msg=audit(1226874073.147:96): arch=40000003 syscall=196 success=no exit=-13
a0=b98df198 a1=bfec85dc a2=54dff4 a3=2008171 items=0 ppid=2463 pid=2465 auid=502 uid=48
gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=6 comm="httpd"
exe="/usr/sbin/httpd" subj=unconfined_u:system_r:httpd_t:s0 key=(null)



  • msg=audit(1226874073.147:96)
    • The number in parentheses is the unformatted time stamp (Epoch time)
for the event, which can be converted to standard time by using the
date command.

  • { getattr }
    • The item in braces indicates the permission that was denied. getattr
indicates the source process was trying to read the target file's status information.
This occurs before reading files. This action is denied due to the file being
accessed having the wrong label. Commonly seen permissions include getattr,
read, and write.
  • comm="httpd"
    • The executable that launched the process. The full path of the executable is
found in the exe= section of the system call (SYSCALL) message,
which in this case, is exe="/usr/sbin/httpd".

  • path="/var/www/html/file1"
    • The path to the object (target) the process attempted to access.

  • scontext="unconfined_u:system_r:httpd_t:s0"
    • The SELinux context of the process that attempted the denied action. In
this case, it is the SELinux context of the Apache HTTP Server, which is running
in the httpd_t domain.

  • tcontext="unconfined_u:object_r:samba_share_t:s0"
    • The SELinux context of the object (target) the process attempted to access.
In this case, it is the SELinux context of file1. Note: the samba_share_t
type is not accessible to processes running in the httpd_t domain.
  •  From the system call (SYSCALL) message, two items are of interest:

    • success=no: indicates whether the denial (AVC) was enforced or not.
success=no indicates the system call was not successful (SELinux denied
access). success=yes indicates the system call was successful - this can
be seen for permissive domains or unconfined domains, such as initrc_t
and kernel_t.

    • exe="/usr/sbin/httpd": the full path to the executable that launched
the process, which in this case, is exe="/usr/sbin/httpd".

    

Group  
                Configure auditd Rules for Comprehensive Auditing
                          Group contains 8 groups and 116 rules
[ref]  
                        The auditd program can perform comprehensive
monitoring of system activity. This section describes recommended
configuration settings for comprehensive auditing, but a full
description of the auditing system's capabilities is beyond the
scope of this guide. The mailing list linux-audit@redhat.com exists
to facilitate community discussion of the auditing system.



The audit subsystem supports extensive collection of events, including:



  • Tracing of arbitrary system calls (identified by name or number)
on entry or exit.
  • Filtering by PID, UID, call success, system call argument (with
some limitations), etc.
  • Monitoring of specific files for modifications to the file's
contents or metadata.



Auditing rules at startup are controlled by the file /etc/audit/audit.rules.
Add rules to it to meet the auditing requirements for your organization.
Each line in /etc/audit/audit.rules represents a series of arguments
that can be passed to auditctl and can be individually tested
during runtime. See documentation in /usr/share/doc/audit-VERSION and
in the related man pages for more details.



If copying any example audit rulesets from /usr/share/doc/audit-VERSION,
be sure to comment out the
lines containing arch= which are not appropriate for your system's
architecture. Then review and understand the following rules,
ensuring rules are activated as needed for the appropriate
architecture.



After reviewing all the rules, reading the following sections, and
editing as needed, the new rules can be activated as follows:

$ sudo service auditd restart
Group  
                Record Events that Modify the System's Discretionary Access Controls
                          Group contains 13 rules
[ref]  
                        At a minimum, the audit system should collect file permission
changes for all users and root. Note that the "-F arch=b32" lines should be
present even on a 64 bit system. These commands identify system calls for
auditing. Even if the system is 64 bit it can still execute 32 bit system
calls. Additionally, these rules can be configured in a number of ways while
still achieving the desired effect. An example of this is that the "-S" calls
could be split up and placed on separate lines, however, this is less efficient.
Add the following to /etc/audit/audit.rules:

-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
    -a always,exit -F arch=b32 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -F key=perm_mod
    -a always,exit -F arch=b32 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod

If your system is 64 bit then these lines should be duplicated and the
arch=b32 replaced with arch=b64 as follows:

-a always,exit -F arch=b64 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod
    -a always,exit -F arch=b64 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -F key=perm_mod
    -a always,exit -F arch=b64 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
Rule  
                                Record Events that Modify the System's Discretionary Access Controls - chmod
                                  [ref]
At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured to
use the augenrules program to read audit rules during daemon startup
(the default), add the following line to a file with suffix .rules in
the directory /etc/audit/rules.d:

-a always,exit -F arch=b32 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod

If the system is 64 bit then also add the following line:

-a always,exit -F arch=b64 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:

-a always,exit -F arch=b32 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod

If the system is 64 bit then also add the following line:

-a always,exit -F arch=b64 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect.  Here the system calls
have been placed independent of other system calls.  Grouping these system
calls with others as identifying earlier in this guide is more efficient.
Rationale:
The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users.

Rationale:
Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.



Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity.

Rationale:
Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.



Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity.

utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file, setting ARCH to either b32 or b64 as
appropriate for your system:

-a always,exit -F arch=ARCH -S renameat -F auid>=1000 -F auid!=unset -F key=delete
Rationale:
Auditing file deletions will create an audit trail for files that are removed
from the system. The audit trail could aid in system troubleshooting, as well as, detecting
malicious processes that attempt to delete log files to conceal their presence.

                Record Unauthorized Access Attempts Events to Files (unsuccessful)
                          Group contains 32 rules
[ref]  
                        At a minimum, the audit system should collect unauthorized file
accesses for all users and root. Note that the "-F arch=b32" lines should be
present even on a 64 bit system. These commands identify system calls for
auditing. Even if the system is 64 bit it can still execute 32 bit system
calls. Additionally, these rules can be configured in a number of ways while
still achieving the desired effect. An example of this is that the "-S" calls
could be split up and placed on separate lines, however, this is less efficient.
Add the following to /etc/audit/audit.rules:

-a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
    -a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access

If your system is 64 bit then these lines should be duplicated and the
arch=b32 replaced with arch=b64 as follows:

-a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
    -a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access

The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured

.rules in the directory /etc/audit/rules.d.

-a always,exit -F arch=b32 -S chmod -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S chmod -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S chmod -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Rationale:
Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

                                  [ref]
At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:

-a always,exit -F arch=b32 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:

-a always,exit -F arch=b32 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient.
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S fchmodat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S fchmodat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S fchmodat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S fchmodat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Rationale:
Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient.

Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

                                  [ref]
The audit system should collect unsuccessful file ownership change
attempts for all users and root.

If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.


-a always,exit -F arch=b32 -S lchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S lchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S lchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S lchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Rationale:
Unsuccessful attempts to change ownership of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S lsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S lsetxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S lsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S lsetxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
Rationale:
Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

Rule  
                                Record Unsuccessful Creation Attempts to Files - open_by_handle_at O_CREAT
                                  [ref]
The audit system should collect unauthorized file accesses for
all users and root. The open_by_handle_at syscall can be used to create new files
when O_CREAT flag is specified.

The following auidt rules will asure that unsuccessful attempts to create a
file via open_by_handle_at syscall are collected.

If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create



If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create

Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

Rule  
                                Record Unsuccessful Modification Attempts to Files - open_by_handle_at O_TRUNC_WRITE
                                  [ref]
The audit system should collect detailed unauthorized file accesses for
all users and root. The open_by_handle_at syscall can be used to modify files
if called for write operation of with O_TRUNC_WRITE flag.

The following auidt rules will asure that unsuccessful attempts to modify a
file via open_by_handle_at syscall are collected.

If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification



If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification

Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

Rule  
                                Ensure auditd Unauthorized Access Attempts To open_by_handle_at Are Ordered Correctly
                                  [ref]
The audit system should collect detailed unauthorized file
accesses for all users and root.
To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
of files via open_by_handle_at syscall the audit rules collecting these events need to be in certain order.
The more specific rules need to come before the less specific rules. The reason for that is that more
specific rules cover a subset of events covered in the less specific rules, thus, they need to come
before to not be overshadowed by less specific rules, which match a bigger set of events.
Make sure that rules for unsuccessful calls of open_by_handle_at syscall are in the order shown below.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), check the order of
rules below in a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, check the order of rules below in
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification

-a always,exit -F arch=b64 -S open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access

Rationale:
The more specific rules cover a subset of events covered by the less specific rules.
By ordering them from more specific to less specific, it is assured that the less specific
rule will not catch events better recorded by the more specific rule.

Rule  
                                Record Unsuccessful Creation Attempts to Files - open O_CREAT
                                  [ref]
The audit system should collect unauthorized file accesses for
all users and root. The open syscall can be used to create new files
when O_CREAT flag is specified.

The following auidt rules will asure that unsuccessful attempts to create a
file via open syscall are collected.

If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create



If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create

Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

Rule  
                                Record Unsuccessful Modification Attempts to Files - open O_TRUNC_WRITE
                                  [ref]
The audit system should collect detailed unauthorized file accesses for
all users and root. The open syscall can be used to modify files
if called for write operation of with O_TRUNC_WRITE flag.
The following auidt rules will asure that unsuccessful attempts to modify a
file via open syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification

Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:

-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.

Rule  
                                Ensure auditd Rules For Unauthorized Attempts To open Are Ordered Correctly
                                  [ref]
The audit system should collect detailed unauthorized file
accesses for all users and root.
To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
of files via open syscall the audit rules collecting these events need to be in certain order.
The more specific rules need to come before the less specific rules. The reason for that is that more
specific rules cover a subset of events covered in the less specific rules, thus, they need to come
before to not be overshadowed by less specific rules, which match a bigger set of events.
Make sure that rules for unsuccessful calls of open syscall are in the order shown below.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), check the order of
rules below in a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, check the order of rules below in
/etc/audit/audit.rules file.

-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b32 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b64 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access

Rationale:
The more specific rules cover a subset of events covered by the less specific rules.
By ordering them from more specific to less specific, it is assured that the less specific
rule will not catch events better recorded by the more specific rule.

At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:

-a always,exit -F arch=b32 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access


If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:

-a always,exit -F arch=b32 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access


If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
Warning: 
                                        Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient.
Rationale:
Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise.
