Scope, Purpose, and Application

The Security capability allows an end user service in the originating Signalling Point (SP) to invoke various security functions in the originating and/or destination SP. The Security capability can be used for identification and authentication of the communicating entities. It also provides information that supports resource access control, system access control, and encryption and decryption functions. The Security capability may be invoked by a variety of services. The end user will interact with an end user service which may invoke the Security capability. Note that the specific end user service that invokes Security is not within the scope of this capability description. The Security capability is not visible to the end user, but allows an end user service to take place. Thus, there is a "layering" of services and capabilities. The specification of the different security functions (e.g., identification, authentication, encryption) may be determined by the service or the Signalling point. The information exchange model and information element model for the Security network capability are based on the standards in the Reference section of this description.

A security policy is a statement of the rules that are to be enforced regarding the accessibility of data items and processing functions to entities within the network. In order to state the policy in a meaningful way, it is necessary to mention the threats that the policy is intended to prevent. Informative Annex B provides a threat analysis and security policy overview for Signalling System Number 7 (SS7).

Informative Annex C provides an overview of basic security functions and operation.
