Fix Recommendation

Configure the audit system to generate an audit event for any use of "ssh-keysign" by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file:

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

The audit daemon must be restarted for the changes to take effect. To restart the audit daemon, run the following command:

$ sudo service auditd restart

Check Contents

Verify OL 8 generates an audit record for any use of "ssh-keysign" by running the following command to check the file system rules in "/etc/audit/audit.rules":

$ sudo grep ssh-keysign /etc/audit/audit.rules

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

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

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