Description
During the installation of Microsoft SharePoint, the Central Administration Web site is established on a randomly-assigned TCP port by default. Allowing a randomly-assigned default may result in use of a port which violates DoD policy or conflicts with ports already in use. Use of certain well-known ports may also result in slow operational response or expose the application to known denial of service attacks.
