Description
An attacker has at least two reasons to stop a web server. The first is to cause a denial of service, and the second is to put in place changes the attacker made to the web server configuration. If the Tomcat shutdown port feature is enabled, a shutdown signal can be sent to the ESX Agent Manager through this port. To ensure availability, the shutdown port must be disabled.
