In NAF 4 and UAF, a SecurityControl is a type of OperationalActivity that specifies a safeguard or countermeasure prescribed for OperationalPerformer. It is intended to protect the confidentiality, integrity, and availability of its information.

Since NAF 4 is built using the UAF metamodel, SecurityControl is available in NAF 4 as a definition type. It is not available to be modeled on a diagram type in NAF 4, since NAF 4 does not specifically include Security views.
