In order to take advantage of Network authorization, a Network node must send a Validate message to NAAS when a request is received, and the Validate message must contain a ResourceURI parameter, which identifies the requested resources. (Please see the Network Security Specifications for the format of the ResourceURI parameter). Contact the Network Help Desk for assistance (nodehelpdesk@csc.com).

The authorization process determines Who (the subject) can do What (the operation), where (the resource) based on policies put in place by each Node administrator for their own node. NAAS makes decisions based on these policies.

Note that NAAS will not be able to make authorization decisions if the ResourceURI parameter is not provided.
