Network device that forwards traffic between different networks, directing packets to their destinations.
A router forwards network traffic between different networks, determining the best path for packets to reach their destinations. Routers connect your internal network to the internet and handle traffic between network segments. Modern routers often include firewall functionality. Router security is critical—compromised routers can intercept traffic, redirect connections, or provide persistent access to attackers.
Why It Matters
The DSC Perspective:
Routers are critical infrastructure. Ensure routers are properly configured, regularly updated, and securely managed. Default credentials and outdated firmware are common router vulnerabilities.
