Title

SLEM 5 must generate audit records for the "/run/utmp file". (Cat II impact)

Discussion

Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Check Content

Verify SLEM 5 generates an audit record for the "/run/utmp" file with the following command: > sudo auditctl -l | grep -w '/run/utmp' -w /run/utmp -p wa -k login_mod If the command does not return a line that matches the example, this is a finding. Note: The "key=" value is arbitrary and can be different from the example output above.

Fix Text

Configure SLEM 5 to generate an audit record for the "/run/utmp" file. Add or modify the following lines in the "/etc/audit/rules.d/audit.rules" file: -w /run/utmp -p wa -k login_mod To reload the rules file, restart the audit daemon: > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load
