It is difficult to overstate the importance of the internet to modern business and society in general. The internet is not a single network, but rather a complex grid of independent interconnected networks that relies on a protocol known as Border Gateway Protocol (BGP) to route traffic to its intended destination.
Unfortunately, BGP was not designed with security in mind and a route hijack attack can deny access to internet services, misdeliver traffic to malicious endpoints, and cause routing instability. A technique known as BGP route origin validation (ROV) is designed to protect against route hijacking.
The NCCoE, together with several technology vendors, has developed proof-of-concept demonstrations of BGP ROV implementation designed to improve the security of the internet's routing infrastructure.
This cybersecurity practice guide contains step-by-step example solutions using commercially available technologies. By implementing the example solutions, organizations can better secure the safe delivery of internet traffic to its intended destination, reduce the number of outages due to BGP route hijacks, and make more informed decisions regarding routes that may be compromised.
