Fix Recommendation

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

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

-a always,exit -F path=/usr/bin/chmod -F perm=x -F auid>=500 -F auid!=4294967295 -k prim_mod

The audit daemon must be restarted for the changes to take effect.

# sudo systemctl restart auditd.service

Check Contents

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

Check that the following command call is being audited by performing the following command to check the file system rules in "/etc/audit/audit.rules":

# sudo grep -i chmod /etc/audit/audit.rules

-a always,exit -F path=/usr/bin/chmod -F perm=x -F auid>=500 -F auid!=4294967295 -k prim_mod

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