Description
Discussion Text
Information systems are capable of providing a wide variety of functions and services. Some of the default functions and services 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.
Applications must adhere to the principles of least functionality by providing only essential capabilities.
SQL Server may spawn additional external processes to execute procedures that are defined in the SQL Server but stored in external host files (external procedures). The spawned process used to execute the external procedure may operate within a different OS security context than SQL Server and provide unauthorized access to the host system.
The Allow Polybase Export feature allows an export of data to an external data source such as Hadoop File System or Azure Data Lake. An exploit to the SQL Server instance could result in a compromise of the host system and external SQL Server resources.
