Rule
Check-Block-05: Does cinder communicates with nova over TLS?
[ref] | OpenStack components communicate with each other using various protocols and the communication might involve sensitive / confidential data. An attacker may try to eavesdrop on the channel in order to get access to sensitive information. Thus all the components must communicate with each other using a secured communication protocol.
Pass: If value of parameter nova_api_insecure under [DEFAULT] section in /etc/cinder/cinder.conf is set to False.
Fail: If value of parameter nova_api_insecure under [DEFAULT] section in /etc/cinder/cinder.conf is set to True. | | Rationale: | | | Severity: | unknown | | Identifiers and References | References:

Rule
Check-Block-07: Is NAS operating in secure enviornment?
[ref] | Cinder supports an NFS driver which works differently than a traditional block storage driver. The NFS driver does not actually allow an instance to access a storage device at the block level. Instead, files are created on an NFS share and mapped to instances, which emulates a block device. Cinder supports secure configuration for such files by controlling the file permissions when cinder volumes are created. Cinder configuration can also control whether file operations are run as the root user or the current OpenStack process user.
Pass: If value of parameter nas_secure_file_permissions under [DEFAULT] section in /etc/cinder/cinder.conf is set to auto. When set to auto, a check is done during cinder startup to determine if there are existing cinder volumes, no volumes will set the option to True, and use secure file permissions. The detection of existing volumes will set the option to False, and use the current insecure method of handling file permissions. If value of parameter nas_secure_file_operations under [DEFAULT] section in /etc/cinder/cinder.conf is set to auto. When set to “auto”, a check is done during cinder startup to determine if there are existing cinder volumes, no volumes will set the option to True, be secure and do NOT run as the root user. The detection of existing volumes will set the option to False, and use the current method of running operations as the root user. For new installations, a “marker file” is written so that subsequent restarts of cinder will know what the original determination had been.
Fail: If value of parameter nas_secure_file_permissions under [DEFAULT] section in /etc/cinder/cinder.conf is set to False and if value of parameter nas_secure_file_operations under [DEFAULT] section in /etc/cinder/cinder.conf is set to False. | | Rationale: | | | Severity: | unknown | | Identifiers and References | References:

Check-Block-03: Is keystone used for authentication?
[ref] | OpenStack supports various authentication strategies like noauth, keystone etc. If the ‘noauth’ strategy is used then the users could interact with OpenStack services without any authentication. This could be a potential risk since an attacker might gain unauthorized access to the OpenStack components. Thus it is strongly recommended that all services must be authenticated with keystone using their service accounts.
Pass: If value of parameter auth_strategy under [DEFAULT] section in /etc/cinder/cinder.conf is set to keystone.

Check-Block-01: Is user/group ownership of config files set to root/cinder?
[ref] | Configuration files contain critical parameters and information required for smooth functioning of the component. If an unprivileged user, either intentionally or accidentally, modifies or deletes any of the parameters or the file itself then it would cause severe availability issues resulting in a denial of service to the other end users. Thus user ownership of such critical configuration files must be set to root and group ownership must be set to cinder.
Run the following commands:

Check-Block-08: Is max size for the body of a request set to default (114688)?
[ref] | If the maximum body size per request is not defined, the attacker can craft an arbitrary osapi request of large size causing the service to crash and finally resulting in Denial Of Service attack. Assigning the maximum value ensures that any malicious oversized request gets blocked ensuring continued availability of the service.
Pass: If value of parameter osapi_max_request_body_size under [DEFAULT] section in /etc/cinder/cinder.conf is set to 114688 or if value of parameter max_request_body_size under [oslo_middleware] section in /etc/cinder/cinder.conf is set to 114688.

If an unprivileged user, either intentionally or accidentally modifies or deletes any of the parameters or the file itself then it would cause severe availability issues causing a denial of service to the other end users. Thus user and group ownership of such critical configuration files must be set to that component owner.
Run the following commands:

Check-Identity-06: Disable admin token in /etc/keystone/keystone.conf
[ref] | The admin token is generally used to bootstrap Identity. This token is the most valuable Identity asset, which could be used to gain cloud admin privileges.
Pass: If admin_token under [DEFAULT] section in /etc/keystone/keystone.conf is disabled. And, AdminTokenAuthMiddleware under [filter:admin_token_auth] is deleted from /etc/keystone/keystone-paste.ini

Rule
Set Account Lockout Duration
[ref] | Once a user account is locked out, such as exceeding the
amount of logon attempts as defined by lockout_failure_attempts,
Keystone will lockout an account for the time period defined by the
lockout_duration configuration option unde the
[security_compliance] section in keystone.conf.
Note that if lockout_failure_attempts is enabled and
lockout_duration is left undefined, users will be
locked out indefinitely until the user is explicitly re-enabled. | | Rationale: | Defining a lockout duration helps mitigate certain attacks,
such as brute force attempts. Additionally defining a lockout
duration, versus indefinately locking an account, lowers
administrative burden of re-enabling accounts of users
who accidentally triggered the maximum failure attempts. | | Severity: | medium | | Identifiers and References | References:
AC-7(2) | |
|
Rule
Set Maximum Number of Failed Authentication Attempts
[ref] | The account lockout feature limits the number of incorrect password
attempts. If a user fails to authenticate after the maximum number
of attempts, the service disables the user.
The maximum number of failed authentication attempts is set by the
lockout_failure_attempts option in under the
[security_compliance] section in keystone.conf. | | Rationale: | Defining a maximum number of failed logon attempts can help
mitigate brute force password attacks. | | Severity: | medium | | Identifiers and References | References:
AC-7(1) | |

Rule
Set Maximum Inactivity Period
[ref] | Keystone can be configured to disable accounts after an
organizationally-defined time period. This is achieved by configuring the
disable_user_account_days_inactive setting in the
[security_compliance] section in keystone.conf. | | Rationale: | Automatically disabling accounts ensures that users who have not
authenticated for an organizationally-defined time period are
automatically disabled. This reduces the risk of stale accounts
being used for malicious purposes. | | Severity: | medium | | Identifiers and References | References:

Check-Identity-05: Is max_request_body_size set to default (114688)?
[ref] | The parameter max_request_body_size defines the maximum body size per request in bytes. If the maximum size is not defined, the attacker could craft an arbitrary request of large size causing the service to crash and finally resulting in Denial Of Service attack. Assigning the maximum value ensures that any malicious oversized request gets blocked ensuring continued availability of the component.
Pass: If value of parameter max_request_body_size in /etc/keystone/keystone.conf is set to default (114688) or some reasonable value based on your environment.

Rule
Check-Identity-04: Does Identity use strong hashing algorithms for PKI tokens?
[ref] | MD5 is a weak and depreciated hashing algorithm. It can be cracked using brute force attack. Identity tokens are sensitive and need to be protected with a stronger hashing algorithm to prevent unauthorized disclosure and subsequent access.
Pass: If value of parameter hash_algorithm under [token] section in /etc/keystone/keystone.conf is set to SHA256.

The access rights can also be validated using the following command. This command will only be available on your system if it supports ACLs.
$ getfacl --tabular -a /etc/openstack-dashboard/local_settings
getfacl: Removing leading '/' from absolute path names
# file: etc/openstack-dashboard/local_settings
USER root rw-
GROUP horizon r--
mask r--
other ---

Check-Dashboard-06: Is SESSION_COOKIE_HTTPONLY parameter set to True?
[ref] | The “HTTPONLY” cookie attribute instructs web browsers not to allow scripts (e.g. JavaScript or VBscript) an ability to access the cookies via the DOM document.cookie object. This session ID protection is mandatory to prevent session ID stealing through XSS attacks.
Pass: If value of parameter SESSION_COOKIE_HTTPONLY in /etc/openstack-dashboard/local_settings is set to True.
Fail: If value of parameter SESSION_COOKIE_HTTPONLY in /etc/openstack-dashboard/local_settings is set to False. | | Rationale: | | | Severity: | unknown | | Identifiers and References | | |

Check-Dashboard-05: Is SESSION_COOKIE_SECURE parameter set to True?
[ref] | The “SECURE” cookie attribute instructs web browsers to only send the cookie through an encrypted HTTPS (SSL/TLS) connection. This session protection mechanism is mandatory to prevent the disclosure of the session ID through MitM (Man-in-the-Middle) attacks. It ensures that an attacker cannot simply capture the session ID from web browser traffic.
Pass: If value of parameter SESSION_COOKIE_SECURE in /etc/openstack-dashboard/local_settings is set to True.
Fail: If value of parameter SESSION_COOKIE_SECURE in /etc/openstack-dashboard/local_settings is set to False. | | Rationale: | | | Severity: | unknown | | Identifiers and References | | |
