Title

Access to Central Administration site must be limited to authorized users and groups. (Cat II impact)

Discussion

SharePoint must prevent the presentation of information system management-related functionality at an interface utilized by general, (i.e., non-privileged), users administrative interfaces to non-privileged users. Information system management functionality includes: functions necessary to administer databases, network components, workstations, or servers, and typically requires privileged user access. The separation of user functionality from information system management functionality is either physical or logical and is accomplished by using different computers, different central processing units, different instances of the operating system, different network addresses, combinations of these methods, or other methods as appropriate. An example of this type of separation is observed in web administrative interfaces that use separate authentication methods for users of any other information system resources. This may include isolating the administrative interface on a different domain and with additional access controls. The Central Administrator is the web application used to manage SharePoint system configuration and web application settings.
