Description
OpenShift follows the principle of least privilege, which aims to restrict access to resources based on user roles and responsibilities. This separation of privileges helps mitigate the risk of unauthorized modifications or unauthorized access by users or processes that do not need to interact with the file. Protecting the /var/log directory from unauthorized access helps safeguard against potential security threats. Unauthorized users gaining access to the file may exploit vulnerabilities, tamper with logs, or extract sensitive information. By setting strict file owner permissions, OpenShift minimizes the risk of unauthorized individuals or processes accessing or modifying the directory, reducing the likelihood of security breaches.

Check Text ( C-61266r921534_chk )
Verify the "/var/log" directory is group-owned by root by executing the following command: for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; stat -c "%G" /var/log' 2>/dev/null; done If "root" is not returned as a result, this is a finding.

Fix Text (F-61190r921535_fix)
Correct log directory ownership by executing the following: for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; chown root:root /var/log/' 2>/dev/null; done
