SLEM 5 must have the auditing package installed.

Without establishing what type of events occurred, the source of events, where events occurred, and the outcome of events, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack.

Audit record content that may be necessary to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked.

Associating event types with detected events in SLEM 5 audit logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured SLEM 5.

Verify SLEM 5 auditing package is installed with the following command:

     > zypper info audit 
     Name           : audit
     Version        : 2.8.5-3.2
     Arch           : X86_64
     Vendor         : SUSE LLC <https://www.suse.com>
     Installed Size : 646.2 KiB
     Installed      : Yes (automatically)
     Status         : up-to-date

If the package "audit" is not installed on the system, this is a finding.

Install SLEM 5 auditing package with the following commands:

     > sudo transactional-update pkg install audit
     > sudo reboot
