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. Therefore, only administrators should ever be able to stop VAMI. The VAMI is configured out of the box to be owned by root. This configuration must be verified and maintained.
