Change the permissions and ownership of files located under "/var/log/pods" to protect from unauthorized access.
1. Execute the following to set the output of pods readable only by the owner:
for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; find /var/log/pods/ -type f \( -perm /022 -o -perm /044 \) | xargs -r chmod 600' 2>/dev/null; done
2. Execute the following to set the group and group-ownership to root for files that store the output of pods:
for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; find /var/log/pods/ -type f \! -user 0 | xargs -r chown root:root' 2>/dev/null; done
Verify the permissions and ownership of files located under "/var/log/pods" that store the output of pods are set to protect from unauthorized access.
1. Verify the files are readable only by the owner by executing the following command:
for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; find /var/log/pods/ -type f \( -perm /022 -o -perm /044 \)' 2>/dev/null; done
If any files are returned, this is a finding.
2. Verify files are group-owned by root and owned by root by executing the following:
for node in $(oc get node -oname); do oc debug $node -- chroot /host /bin/bash -c 'echo -n "$HOSTNAME "; find /var/log/pods/ -type f \! -user 0' 2>/dev/null; done
(Example output:
ip-10-0-150-1 root root)
If "root" is not returned as the owner, this is a finding.
If "root" is not returned as the group owner, this is a finding.
