Description
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 the mission. Applications must adhere to the principles of least functionality by providing only essential capabilities. Unused, unnecessary DBMS components increase the attack surface of the DBMS 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.

Check Text ( C-54291r2_chk )
Review the DBMS for unused components of the system that cannot be uninstalled. If unused components or features are present on the system and are not disabled, this is a finding. SQLPlus can be used to check to see what is installed in the database: sqlplus connect as sysdba select from v$option; This will return all of the database options and their status. TRUE means that the option is installed. If the option is not installed, the option will be set to FALSE. Review the options and check to see what is required.
