Non-repudiation of actions taken is required in order to maintain integrity. To do this, we will prevent users from modifying the audit logs. Non-repudiation protects individuals against later claims by an author of not having updated a particular file, invoked a specific command, or copied a specific file. |

To check the ownership of the audit log files, run the following command: sudo -s ls -n `sudo grep "^dir" /etc/security/audit_control | awk -F: '{print $2 "/*"}'` | awk '{ print $3 ":" $4 ":" $9 }' The results should read "0:0" in the first column. The first "0" is UID, the second is GID, with the first "0" being root, and the second "0" being wheel. If not, this is a finding. |

For every log file that is not owned by root, run the following command: sudo chown root:wheel [audit log file] where [audit log file] is the full path of the log file that needs to be modified. |
