A.2.8 Control layer security management functional element

The CL security management is an optional functional element responsible for security management of the
SDN-CL. It provides capabilities for:
– managing authentication and authorization capabilities of the SDN-CL;
– detecting and avoiding anomalous attacks towards the SDN-CL;
– storing and providing APIs for querying the contents discovered by the CL resource discovery
functional element;
– storing and providing APIs for querying the contents generated by the CL resource monitoring and
analytics functional element;
– ensuring lifecycle management of the contents in the repository (e.g., creation by storing,
modification, deletion)

A.2.9 Control layer policy management functional element
The CL policy management functional component provides capabilities to define, store and retrieve policies
that apply to CL services. Policies can include business, technical, security, privacy and certification policies
that apply to CL services and their usage by SDN applications.

Some policies can be general and apply to a CL service irrespective of the SDN application concerned. Other
policies can be specific to a particular SDN application.

A.2.10 Control layer multi-layer orchestration support functional element
The CL multi-layer orchestration support functional element provides an internal interface to the multi-layer
orchestration support functional element in the MMO functional component for requesting and receiving
management operations and associated information for multi-layer orchestration specific to control layer
management.
