SLEM 5 must generate audit records for all uses of the "sudoedit" command.

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).

Verify an audit record is generated for all uses of the "sudoedit" command with the following command:

     > sudo auditctl -l | grep -w '/usr/bin/sudoedit'
     -a always,exit -S all -F path=/usr/bin/sudoedit -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-sudoedit

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

Note: The "key=" value is arbitrary and can be different from the example output above.

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

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

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

To reload the rules file, restart the audit daemon:

     > sudo systemctl restart auditd.service

or issue the following command:

     > sudo augenrules --load
