Fix Recommendation

Configure SLEM 5 to generate an audit record for all uses of the "chown", "fchown", "fchownat", and "lchown" system calls.

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

-a always,exit -F arch=b32 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -k perm_mod
-a always,exit -F arch=b64 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=unset -k perm_mod

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 SLEM 5 generates an audit record for all uses of the "chown", "fchown", "fchownat", and "lchown" system calls with the following command:

> sudo auditctl -l | grep chown
-a always,exit -F arch=b32 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=-1 -F key=perm_mod
-a always,exit -F arch=b64 -S chown,fchown,fchownat,lchown -F auid>=1000 -F auid!=-1 -F key=perm_mod

If both the "b32" and "b64" audit rules are not defined for the "chown", "fchown", "fchownat", and "lchown" syscalls, this is a finding.

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