Secure routing and switching are foundational elements of network security. In this episode, we explore how routers and switches operate, and how attackers exploit their misconfigurations or weaknesses to gain access or disrupt communication. Topics include route hijacking, ARP poisoning, MAC flooding, and VLAN hopping. You’ll learn best practices for hardening these devices, including access control lists (ACLs), management plane protection, port security, and proper firmware management. Ensuring routing and switching infrastructure is properly secured is a critical skill for any CISSP responsible for protecting the integrity of network environments.
