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.
