NIST and the Department of Homeland Security (DHS) Science and Technology Directorate have recently worked in collaboration with the industry internet to increase the cybersecurity of electronic messages and data flowing through the internet.
A new set of standards called Secure Inter-Domain Routing (SIDR), has been published by the Internet Engineering Task Force (IETF). This represents the first standardized approach for global defense against sophisticated attacks on the internet’s routing system.
The new standards will help overcome the vulnerabilities within the Border Gateway Protocol (BGP), a system that the Internet's core routers use to direct traffic. BGP forms the technical glue holding the internet together, but historically, its lack of security mechanisms makes it an easy target for hacking.
The overall defensive effort will use cryptographic methods to ensure routing data travels along an authorized path between networks. There are three essential components of the IETF SIDR effort:
