Verify /etc/shadow has no extended ACL. # ls -lL /etc/shadow If the permissions include a "+", the file has an extended ACL, this is a finding. If the /etc/shadow file does not exist and the system is in Trusted Mode, this is not a finding. To verify Trusted Mode: # ls -lLR /tcb/files/auth/[a-z,A-Z]* The TCB file(s) should exist and must not have extended ACLs.
