Information technology. Open systems interconnection. Upper layers security model Ingestion-build-64721 • INTRODUCTION1 Scope 1. 1 This Recommendation International Standard defines an architectural model that provides a basis for: a) the development of application independent services and protocols for security in the upper layers of OSI; and b) the utilization of these services and protocols to fulfil the security requirements of a wide variety of applications, so that the need for application specific ASEs to contain internal security services is minimized.
