Fix Recommendation

Configure the SUSE operating system to generate an audit record for all uses of the "ssh-agent" command.

Add or update the following rules 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!=4294967295 -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

Check Contents

Verify the SUSE operating system generates an audit record for all uses of the "ssh-agent" command.

Check that the command is being audited by performing the following command:

> sudo auditctl -l | grep -w '/usr/bin/ssh-agent'

-a always,exit -S all -F path=/usr/bin/ssh-agent -F perm=x -F auid>=1000 -F auid!=-1 -k privileged-ssh-agent

If the command does not return any output or the returned line is commented out, this is a finding.

Note:
The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.
