Title

LockOutRealm must not be removed from Apache Tomcat. (Cat II impact)

Discussion

LockOutRealm prevents brute force attacks against user passwords. Removal of unneeded or nonsecure functions, ports, protocols, and services mitigate the risk of unauthorized connection of devices, unauthorized transfer of information, or other exploitation of these resources. The organization must perform a periodic scan/review of the application (as required by CCI-000384) and disable functions, ports, protocols, and services deemed to be unneeded or nonsecure.
