Vulnerability Discussion

A web server can provide many features, services, and processes. Some of these may be deemed unnecessary or too unsecure to run on a production DoD system.

The web server must provide the capability to disable, uninstall, or deactivate functionality and services deemed non-essential to the web server mission or that adversely impact server performance.
