Router Security

Definitions

1. The protection of routers and their control planes, management interfaces, firmware, routing protocols, and configuration against compromise or abuse. Router security matters because routers influence traffic flow, segmentation, visibility, and resilience across entire networks.

   In plain English: Security for routers and the network traffic paths they control.

   Example: "The provider tightened router security by restricting admin access, signing config changes, and disabling unnecessary services on edge devices."
