Determine the amount of audit data (in megabytes) which should be retained in each log file. Edit the file "/etc/audit/auditd.conf". Add or modify the following line, substituting the correct value for [STOREMB]:

max_log_file = [STOREMB]

Set the value to "6" (MB) or higher for general-purpose systems. Larger values, of course, support retention of even more audit data.
