Fix Recommendation

Configure the SUSE operating system to generate audit records when successful/unsuccessful attempts to modify categories of information (e.g., classification levels) occur.

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

-a always,exit -F path=/usr/bin/chcon -F perm=x -F auid>=1000 -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 audit records are generated when successful/unsuccessful attempts to modify categories of information (e.g., classification levels) occur.

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 'chcon' /etc/audit/audit.rules

-a always,exit -F path=/usr/bin/chcon -F perm=x -F auid>=1000 -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.
