RHEL9 STIG v2r9 requires auid filters for the following audit rules: - RHEL-09-654250: audit_rules_login_events_faillock - RHEL-09-654255: audit_rules_login_events_lastlog RHEL10 STIG v1r2 does NOT require auid filters for the equivalent rules: - RHEL-10-500750 - RHEL-10-500760 This commit removes the templates from rule.yml and provides: 1. **shared.sh/yml/xml** - Template-derived content (no auid filters) used by: - rhel8, rhel10, ol7, ol8, ol9, ol10, rhcos4, rhv4 - almalinux9, anolis8, anolis23, fedora - debian11, ubuntu2204, ubuntu2404 - sle12, sle15 2. **rhel9.sh/yml/xml** - Custom RHEL9 content with required auid filters: - Bash: Uses bash_fix_audit_syscall_rule macro with AUID_FILTERS - Ansible: Adds auid>=1000 and auid!=unset to rule patterns - OVAL: Requires auid>=1000 and auid!=unset in pattern matching The generated RHEL9 rules include: ``` -a always,exit -F arch=b32 -F path=/var/run/faillock -F perm=wa -F auid>=1000 -F auid!=unset -k logins -a always,exit -F arch=b64 -F path=/var/run/faillock -F perm=wa -F auid>=1000 -F auid!=unset -k logins ``` And similar for /var/log/lastlog. Test scenarios verify both passing and failing cases for RHEL9. This is a temporary solution until DISA clarifies why RHEL10 STIG doesn't require the auid parameter. If DISA updates RHEL10 to match RHEL9, the custom content can be updated accordingly.
