High Performance Computing Modernization Program

High Performance Computing Modernization Program (HPCMP) Networking Security provides overall security for the Defense Research and Engineering Network (DREN) and Secret Defense Research and Engineering Network (SDREN). As Mission Assurance Category (MAC) III Zone A networks, both networks provide a variety of services and access to all of the HPCMP users for their unclassified and/or classified needs.

Security of the networks is fundamental to meeting the confidentiality, integrity, availability (C-I-A) and non-repudiation (with public-key infrastructure (PKI) services) of user data transmitted over the wide area networks with a defense-in-depth architectural solution. DREN meets the Research Development Test and Evaluation (RDT&E) and HPCMP user needs with a MAC III unclassified sensitive system high network. Users can utilize DREN for internet protocol (IP) layer three services or as a backbone transit network for Zone B and C networking solutions (unclassified as well as classified with use of a High Assurance Internet Protocol Encryptor (HAIPE)). SDREN meets the RDT&E user’s need with a MAC III Classified Secret system high network.

HPCMP Networking Security provides full Information Assurance (IA) Computer Network Defense (CND) to meet C-I-A with two fully accredited wide area networks in accordance with the Defense Information Assurance Certification and Accreditation Process (DIACAP). This includes perimeter defenses at its edges (peering with other networks and in the case of DREN with the Internet at large) and security technologies within the network.
