Abstract
A security access management system for a packet switched data communications network has access management apparatus operatively associated with the packet switches at each entry point of the network. The access management apparatus includes an administrative host processor for examining user terminal authorization information in packets received at the associated packet switch for transmission through the network to destination addresses for the packets. A database associated with the administrative host stores information including levels of authorization of the user terminals for the respective entry point of the network for access to specified destinations, as pre-assigned by the network customer. Also included in the access management apparatus is a validation host processor which responds to comparisons between the user terminal authorization information contained in the packet and the pre-assigned level of authorization for the same user terminal, and, if they correspond, to grant access by that user terminal through the associated packet switch to the destination address with which a communication session is requested; or, if they differ, to deny such access. The access ma…
