Verify OpenShift is configured to generate audit records when successful/unsuccessful attempts to access or delete security objects, security levels, and privileges occur by executing the following: for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; grep -e "key=perm_mod" -e "key=unsuccessful-create" -e "key=unsuccessful-modification" -e

Discussion

OpenShift and its components must generate audit records when successful/unsuccessful attempts to access or delete security objects, security levels, and privileges occur. All the components must use the same standard so that the events can be tied together to understand what took place within the overall container platform. This must establish, correlate, and help assist with investigating the events relating to an incident, or identify those responsible. Without audit record generation, access controlscontrol levels can be accessed by unauthorized users unknowingly for malicious intent, creating vulnerabilities within the container platform.
