Vulnerability discussion

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).It is detrimental for applications to provide or install by default, functionality exceeding requirements or mission objectives. Examples include, but are not limited to, installing advertising software demonstrations or browser plug-ins not related to requirements or providing a wide array of functionality not required for every mission, yet cannot be disabled. Applications must adhere to the principles of least functionality by providing only essential capabilities.Unused and unnecessary SQL Server components increase the number of available attack vectors to SQL Server by introducing additional targets for attack. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced.SQL Server must have the SQL Server Analysis Service (SSAS) software component removed from SQL Server if SSAS is unused.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
