Fix Recommendation

Edit the "/etc/security/audit_control" file and change the value for "expire-after" to the amount of time audit logs should be kept for the system. Use the following command to set the "expire-after" value to "7d":

/usr/bin/sudo /usr/bin/sed -i.bak 's/.*expire-after.*/expire-after:7d/' /etc/security/audit_control; /usr/bin/sudo /usr/sbin/audit -s

A text editor may also be used to implement the required updates to the "/etc/security/audit_control" file.

Check Contents

The check displays the amount of time the audit system is configured to retain audit log files. The audit system will not delete logs until the specified condition has been met. To view the current setting, run the following command:

/usr/bin/sudo /usr/bin/grep ^expire-after /etc/security/audit_control

If this returns no results, or does not contain "7d" or a larger value, this is a finding.
