Abstract
Method and apparatus for use with systems including networked resources where communication between resources is via dual packet protocols wherein a first protocol includes a frame that specifies a destination device/resource and a data field and the second protocol specifies a final destination device/resource and includes a data field, where the second packets are encapsulated in the first protocol packet frames, the method including specifying access control information for resources, for each first protocol packet transmitted on the network, intercepting the first protocol packet prior to the first protocol destination resource, examining a subset of the additional embedded packet information to identify one of the intermediate path resources and the final destination resource, identifying the access control information associated with the identified at least one of the intermediate path resources and the final destination resource and restricting transmission of the first protocol packet as a function of the identified access control information.
