SLEM-05-654095 - SLEM 5 must generate audit records for all uses of the "ssh-agent" command.

Information

Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information.

At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Solution

Configure SLEM 5 to generate an audit record for all uses of the "ssh-agent" command.

Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file:

-a always,exit -F path=/usr/bin/ssh-agent -F perm=x -F auid>=1000 -F auid!=unset -k privileged-ssh-agent

To reload the rules file, restart the audit daemon:

 > sudo systemctl restart auditd.service

or issue the following command:

 > sudo augenrules --load
