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 software products to provide, or install by default, functionality exceeding requirements or mission objectives. DBMSs must adhere to the principles of least functionality by providing only essential capabilities.

Check content

From the server documentation, obtain a listing of required components. Generate a listing of components installed on the server. Click Start >> Type "SQL Server 2016 Installation Center" >> Launch the program >> Click Tools >> Click "Installed SQL Server features discovery report" Compare the feature listing against the required components listing. If any features are installed, but are not required, this is a finding.

Fix text

Remove all features that are not required.

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.
