Description
Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Check Text ( C-65166r996716_chk )
Verify SLEM 5 generates an audit record for any use of the "pam_timestamp_check" command with the following command: > sudo auditctl -l \| grep -w '/sbin/pam_timestamp_check' -a always,exit -S all -F path=/sbin/pam_timestamp_check -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-pam_timestamp_check If the command does not return any output, this is a finding. Note: The "key=" value is arbitrary and can be different from the example output above.

Verify SLEM 5 generates an audit record for any use of the "pam_timestamp_check" command with the following command:

> sudo auditctl -l | grep -w '/sbin/pam_timestamp_check'
-a always,exit -S all -F path=/sbin/pam_timestamp_check -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-pam_timestamp_check

If the command does not return any output, this is a finding.

Fix Text (F-65074r996717_fix)
Configure SLEM 5 to generate an audit record for all uses of the "pam_timestamp_check" command. Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/sbin/pam_timestamp_check -F perm=x -F auid>=1000 -F auid!=unset -k privileged-pam_timestamp_check To reload the rules file, restart the audit daemon: > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
