What is BGP in Cybersecurity?
Border Gateway Protocol is the routing protocol that controls how data traverses the internet. BGP exchanges routing information between autonomous systems (large networks like ISPs and cloud providers). Each AS announces the IP prefixes it can reach, and BGP routers select the best path based on policy and path attributes.
Why BGP Matters for Your Cybersecurity Career
BGP hijacking is a serious internet-scale threat where attackers announce false routes to intercept or blackhole traffic. BGP has no built-in authentication, making it vulnerable to route manipulation. Security architects working at ISPs, cloud providers, or large enterprises must understand BGP security measures like RPKI and route filtering.
