Check Contents

Verify the audit rules capture account creation, modification, disabling, removal, and enabling actions 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 user-modify -e group-modify -e audit_rules_usergroup_modification /etc/audit/rules.d/* /etc/audit/audit.rules' 2>/dev/null; done

Confirm the following rules exist on each node:

-w /etc/group -p wa -k audit_rules_usergroup_modification
-w /etc/gshadow -p wa -k audit_rules_usergroup_modification
-w /etc/security/opasswd -p wa -k audit_rules_usergroup_modification
-w /etc/passwd -p wa -k audit_rules_usergroup_modification
-w /etc/shadow -p wa -k audit_rules_usergroup_modification

If the above rules are not listed on each node, this is a finding.

Severity Override Guidance

Verify the audit rules capture account creation, modification, disabling, removal, and enabling actions 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 user-modify -e group-modify -e audit_rules_usergroup_modification /etc/audit/rules.d/* /etc/audit/audit.rules' 2>/dev/null; done

Confirm the following rules exist on each node:

-w /etc/group -p wa -k audit_rules_usergroup_modification
-w /etc/gshadow -p wa -k audit_rules_usergroup_modification
-w /etc/security/opasswd -p wa -k audit_rules_usergroup_modification
-w /etc/passwd -p wa -k audit_rules_usergroup_modification
-w /etc/shadow -p wa -k audit_rules_usergroup_modification

If the above rules are not listed on each node, this is a finding.
