Description
SQL Server is 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, but which 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. Components of the system that are unused and cannot be uninstalled must be disabled.
