Doc Text:	.Files in `/usr/share/audit/sample-rules` are now accepted by SCAP rules Previously, according to the description of SCAP rules `xccdf_org.ssgproject.content_rule_audit_ospp_general` and `xccdf_org.ssgproject.content_rule_audit_immutable_login_uids`, users were able to make systems compliant by copying appropriate files from the `/usr/share/audit/sample-rules` directory. However, OVAL checks of these rules failed, and the system was consequently marked as non-compliant after the scan. With this update, the OVAL checks now accept the files from `/usr/share/audit/sample-rules`, and the SCAP rules pass successfully.	Story Points:	---

Description Lark Gordon 2021-09-01 17:32:03 UTC

Description of problem:

oscap scans reports that 30-ospp-v42.rules and 11-loginuid.rules do not match the sample rules in /usr/share/audit/sample-rules if 10-base-config.rules has been changed.

Version-Release number of selected component (if applicable):

scap-security-guide-0.1.54-5.el8.noarch

How reproducible:
Easily reproducible if  10-base-config.rules. The customer needs to change the buffer size but sees other rules are also flagged whenever they change that file.

Steps to Reproduce:
1. Copy the files from /usr/share/audit/sample-rules to /etc/audit/rules.d/ and make some change to a file (in this case the customer is editing 10-base-config.rules).

2. Scan the system with oscap using the xccdf_org.ssgproject.content_profile_ospp profile from /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml

3. The scan shows that 10-base-config.rules is changed (expected) as well as 30-ospp-v42.rules and 11-loginuid.rules (not expected).

Actual results:
The scan shows that 10-base-config.rules is changed (expected) as well as 30-ospp-v42.rules and 11-loginuid.rules (not expected) if 10-base-config.rules is changed.


Expected results:
The scan should only fail 10-base-config.rules since these files are all checked individually.
