Description
Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default or selected for installation by an administrator, may not be necessary to support essential organizational operations (e.g., key missions, functions). 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. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced. The Data Quality Client software component must be removed from SQL Server if it is unused.
