A new draft publication from the NIST National Cybersecurity Center of Excellence (NCCoE) takes aim at security concerns about the Border Gateway Protocol (BGP), the default routing protocol to route traffic among Internet domains. The paper, "Protecting the Integrity of Internet Routing: Border Gateway Protocol (BGP) Route Origin Validation," is open for public comment until Oct. 15.

Draft SP 1800-14 was developed in cooperation with AT&T, CenturyLink, Cisco, Comcast, Juniper, Palo Alto Networks, and The George Washington University. It describes Route Origin Validation (ROV), a technique intended to shield BGP routers and the routes they advertise from an attack known as route hijacking, in which the bad guys advertise a malicious route, sending traffic to illegitimate servers, routers, or both.

Rather than describing new technology, the paper describes " ... how networks can protect BGP routes from vulnerability to route hijacks by using available security protocols, products, and tools to perform BGP ROV to reduce route hijacking threats," according to NIST.
