Configure OL 8 to generate audit records for any use of the "rename", "unlink", "rmdir", "renameat", and "unlinkat" system calls by adding or updating the following lines to "/etc/audit/rules.d/audit.rules":
-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. To restart the audit daemon, run the following command:
$ sudo service auditd restart
Verify OL 8 is configured to generate audit records for any use of the "rename", "unlink", "rmdir", "renameat", and "unlinkat" system calls by running the following command:
$ sudo grep 'rename\|unlink\|rmdir' /etc/audit/audit.rules
-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.
Note: The "-k" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.
