Check Text ( C-72419r5_chk )
Verify the operating system generates audit records when successful/unsuccessful attempts to use the "pam_timestamp_check" command occur. Check the auditing rules in "/etc/audit/audit.rules" with the following command: # grep -iw "/usr/sbin/pam_timestamp_check" /etc/audit/audit.rules -a always,exit -F path=/usr/sbin/pam_timestamp_check -F auid>=1000 -F auid!=4294967295 -k privileged-pam If the command does not return any output, this is a finding.

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "pam_timestamp_check" command occur.

Check the auditing rules in "/etc/audit/audit.rules" with the following command:

# grep -iw "/usr/sbin/pam_timestamp_check" /etc/audit/audit.rules

-a always,exit -F path=/usr/sbin/pam_timestamp_check -F auid>=1000 -F auid!=4294967295 -k privileged-pam

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

Fix Text (F-78539r4_fix)
Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "pam_timestamp_check" command occur. Add or update the following rule in "/etc/audit/rules.d/audit.rules": -a always,exit -F path=/usr/sbin/pam_timestamp_check -F auid>=1000 -F auid!=4294967295 -k privileged-pam The audit daemon must be restarted for the changes to take effect.
