What are the main security weaknesses of coaxial cable, twisted pair cable, and fiber optic cable? How might the router itself be a security risk, even if you were using UTP/STP cabling that was insulated to prevent electromagnetic radiation leaks that could be eavesdropped on? What steps might you take to improve security for cabled networks?

Answered below

Explanation:

Coaxial cables weaknesses include; fluctuation of speed during heavy use, leaks at the point of connection and signal loss over long distances. Twisted pair cables are not durable enough and are susceptible to interference. Fibre optic cables are costly and need expertise to install.

Hacked or compromised routers can be infected with malwares that reroutes users to spam sites and also to ddos attacks.

Steps to protect cable networks include; network encryption, physical security, VPN usage, updating networks, auditing and mapping.
