Guide to the Secure Configuration of Java Runtime Environment

This guide presents a catalog of security-relevant configuration settings for Java Runtime Environment. 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

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 for Java Runtime Environment, 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.

Group   Remediation functions used by the SCAP Security Guide Project

[ref]   XCCDF form of the various remediation functions as used by remediation scripts from the SCAP Security Guide Project.

Group   Java

[ref]   Java is a general-purpose computer programming language. It is intended to let application developers "write once, run anywhere." Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As such, the Java runtime environment (JRE) is required to be installed so that Java applications can run. This section provides settings for configuring Java policies to meet compliance settings for Java running on Red Hat Enterprise Linux systems.

Group   Configure the deployment.config File

[ref]   The deployment.config file if used for specifying the System-level file. The System-level configuration for Java is configured in /etc/.java/deployment. By default, no deployment.config file exists. To ensure that the Java /etc/.java/deployment/deployment.config file is configured correctly, deployment.system.config and deployment.system.config.mandatory need to be set correctly.
