Security standards for the global information grid

This paper presents an overview of requirements and issues related to improving the infrastructure security of the global information grid (GIG). The context for "hardening" this infrastructure is to develop commercial standards that encourage products to support the GIG. Candidate infrastructure services for such hardening include signaling, routing, management, naming, and service location. The commercial standards of interest for GIG include certain relevant technologies at different stages of maturity, such as, asynchronous transfer mode (ATM), multiprotocol label switching (MPLS), and optical networking. This paper also describes the Department of Defense (DoD) activities aimed toward defining security requirements and standards for hardening of switches and routers that implement these same networking technologies.
