What is Routing in Cybersecurity?
Routing is the process of selecting paths across networks to forward IP packets from source to destination. Routers use routing tables, built by static configuration or dynamic protocols like OSPF and BGP, to determine the best next hop for each packet based on destination address and network metrics.
Why Routing Matters for Your Cybersecurity Career
Attackers manipulate routing to intercept or redirect traffic. BGP hijacking has redirected entire blocks of internet traffic through malicious networks. Security engineers must understand routing to write correct firewall rules, segment networks, and detect route anomalies. Incident responders trace routing paths to identify traffic interception.
