Configure OL 9 to generate an audit event for any successful/unsuccessful use of the rename, unlink, rmdir, renameat, and unlinkat system calls by adding or updating the following rules in the "/etc/audit/rules.d/audit.rules" file:
-a always,exit -F arch=b32 -S rename,unlink,rmdir,renameat,unlinkat -F auid>=1000 -F auid!=unset -k delete
-a always,exit -F arch=b64 -S rename,unlink,rmdir,renameat,unlinkat -F auid>=1000 -F auid!=unset -k delete
The audit daemon must be restarted for the changes to take effect.
Restart auditd:
$ sudo service auditd restart
Verify that OL 9 is configured to audit successful/unsuccessful attempts to use the rename, unlink, rmdir, renameat, and unlinkat system calls with the following command:
$ sudo auditctl -l | grep 'rename\|unlink\|rmdir'
-a always,exit -F arch=b32 -S rename,unlink,rmdir,renameat,unlinkat -F auid>=1000 -F auid!=unset -k delete
-a always,exit -F arch=b64 -S rename,unlink,rmdir,renameat,unlinkat -F auid>=1000 -F auid!=unset -k delete
If the command does not return an audit rule for rename, unlink, rmdir, renameat, and unlinkat or any of the lines returned are commented out, this is a finding.
