OSI - Open System Interconnections

ISO/IEC 19464:2014 defines the Advanced Message Queuing Protocol (AMQP), an open internet protocol for business messaging. It defines a binary wire-level protocol that allows for the reliable exchange of business messages between two parties. AMQP has a layered architecture and the specification is organized as a set of parts that reflects that architecture.

Part 1 defines the AMQP type system and encoding.
Part 2 defines the AMQP transport layer, an efficient, binary, peer-to-peer protocol for transporting messages between two processes over a network.
Part 3 defines the AMQP message format, with a concrete encoding.
Part 4 defines how interactions can be grouped within atomic transactions.
Part 5 defines the AMQP security layers.

The XACML Technical Committee defines a core XML schema for representing authorization and entitlement policies.
 
XACML is expected to address fine grained control of authorized activities, the effect of characteristics of the access requestor, the protocol over which the request is made, authorization based on classes of activities, and content introspection (i.e. authorization based on both the requestor and potentially attribute values within the target where the values of the attributes may not be known to the policy writer). XACML is also expected to suggest a policy authorization model to guide implementers of the authorization mechanism.
