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 vector for 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-62557r1_chk )
Review the DBMS for unused components of the system that cannot be excluded from database creation. If unused components 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 set linesize 121 col parameter format a35 col value format a35 select from v$option; This returns database components and their status. TRUE means that the component is installed. If the component is not installed, it will be set to FALSE or will not be returned by the query. Review the options and check to see what is required.

Review the DBMS for unused components of the system that cannot be excluded from database creation.

If unused components are present on the system and are not disabled, this is a finding.

SQL*PLUS can be used to check to see what is installed in the database:

sqlplus connect as sysdba

set linesize 121
col parameter format a35
col value format a35
select * from v$option;

This returns database components and their status. TRUE means that the component is installed. If the component is not installed, it will be set to FALSE or will not be returned by the query.

Review the options and check to see what is required.

Fix Text (F-67595r1_fix)
If any components are required for operation of applications that will be accessing the DBMS, include them in the system documentation. For Oracle Database 12.1, only the following components can be enabled/disabled: Oracle Data Mining, Oracle OLAP, Oracle Partitioning, Real Application Testing Reference My Oracle Support Document 948061.1 for instructions on how to disable the listed components using the chopt command. usage: chopt
