Check Text ( C-46195r1_chk )
Inspect "/etc/audit/auditd.conf" and locate the following line to determine how many logs the system is configured to retain after rotation: "# grep num_logs /etc/audit/auditd.conf" num_logs = 5 If the overall system log file(s) retention hasn't been properly set up, this is a finding.

Fix Text (F-43585r1_fix)
Determine how many log files "auditd" should retain when it rotates logs. Edit the file "/etc/audit/auditd.conf". Add or modify the following line, substituting [NUMLOGS] with the correct value: num_logs = [NUMLOGS] Set the value to 5 for general-purpose systems. Note that values less than 2 result in no log rotation.
