Description
An attacker has at least two reasons to stop a web server. The first is to cause a DoS, and the second is to put in place changes the attacker made to the web server configuration. As a Tomcat derivative, tc Server uses a port (defaults to 8005) as a shutdown port. If enabled, a shutdown signal can be sent to tc Server through this port. To ensure availability, the shutdown port should be disabled.
