1.1<\/b><\/p>\n
This series of Recommendations | International Standards defines a set of generic facilities to assist in the provision of security services in OSI applications. These include:<\/p>\n
a set of notational tools to support the specification of selective field protection requirements in an abstract syntax specification, and to support the specification of security exchanges and security transformations;<\/p>\n<\/li>\n
a service definition, protocol specification and PICS proforma for an application-service-element (ASE) to support the provision of security services within the Application Layer of OSI;<\/p>\n<\/li>\n
a specification and PICS proforma for a security transfer syntax, associated with Presentation Layer support for security services in the Application Layer.<\/p>\n<\/li>\n<\/ol>\n
1.2<\/b><\/p>\n
This Recommendation | International Standard defines the following:<\/p>\n
general models of security exchange protocol functions and security transformations, based on the concepts described in the OSI Upper Layers Security Model (ITU-T Rec. X.803 | ISO\/IEC 10745);<\/p>\n<\/li>\n
a set of notational tools to support the specification of selective field protection requirements in an abstract syntax specification, and to support the specification of security exchanges and security transformations;<\/p>\n<\/li>\n
a set of informative guidelines as to the application of the generic upper layers security facilities covered by this series of Recommendations | International Standards.<\/p>\n<\/li>\n<\/ol>\n
1.3<\/b><\/p>\n
This Recommendation | International Standard does not define the following:<\/p>\n
a complete set of upper layer security facilities which may be required by other Recommendations | International Standards;<\/p>\n<\/li>\n
a complete set of security facilities for specific applications;<\/p>\n<\/li>\n
the mechanisms employed to support security services.<\/p>\n<\/li>\n<\/ol>\n
1.4<\/b><\/p>\n
The security exchange model, and supporting notation, are intended both for use as the basis of defining the security exchange service element in subsequent parts of this series of Recommendations | International Standards, and for use by any other ASE which may import security exchanges into its own specification.<\/p>\n","protected":false},"excerpt":{"rendered":"
