Description |
---|
The audit service must be configured to create log files with the correct group ownership to prevent regular users from reading audit logs. Audit logs contain sensitive data about the system and users. If log files are set to be readable and writable only by root or administrative users with sudo, the risk is mitigated. |

To check the group ownership of the audit log files, run the following command: /usr/bin/sudo ls -le $(/usr/bin/sudo /usr/bin/grep '^dir' /etc/security/audit_control | awk -F: '{print $2}') | /usr/bin/grep -v current The results should show the group owner (fourth column) to be "wheel". If they do not, this is a finding. |
