REST Service Encoding Specification for Security Markings


This technical specification defines the syntax, protocol and conventions for applying security metadata or notices to a request or a response message conveyed using the Hypertext Transfer Protocol (HTTP).


Adding security metadata and notices to messages provides the capability to route and filter messages based on classification and other security markings. By processing security metadata such as portion markings and tearlines, access control points have the ability to filter data based on the formal authorization credentials of authenticated users.


This specification provides guidance for the implementation of applying such metadata to messages using HTTP or REpresentational State Transfer (REST)-based services.
