RHBA-2020:5451 - Bug Fix Advisory

Topic

An update for scap-security-guide is now available for Red Hat Enterprise
Linux 7.

Description

The scap-security-guide project provides a guide for configuration of the
system from the final system's security point of view. The guidance is
specified in the Security Content Automation Protocol (SCAP) format and
constitutes a catalog of practical hardening advice, linked to government
requirements where applicable. The project bridges the gap between
generalized policy requirements and specific implementation guidelines.

Bug Fix(es) and Enhancement(s):

• The "DISA STIG for Red Hat Enterprise Linux 7" profile in the SCAP Security Guide has been updated to the latest version V3R1. This update adds more coverage and fixes reference problems. The profile is now also more stable and better aligns with the RHEL7 STIG benchmark provided by the Defense Information Systems Agency (DISA).

You should use only the current version of this profile because the older versions of this profile are no longer valid. The OVAL checks for several rules have changed, and scans using the V3R1 version will fail for systems that were hardened using older versions of SCAP Security Guide. You can fix the rules automatically by running the remediation with the new version of SCAP Security Guide.

WARNING: Automatic remediation might render the system non-functional. Run the remediation in a test environment first.

The following rules have been changed:

CCE-80224-9:: The default value of this SSHD configuration has changed from "delayed" to "yes". You must now provide a value according to recommendations. Check the rule description for information about fixing this problem or run the remediation to fix it automatically.
