8 Ways to Improve Wired Network Security

We sometimes focus more on the wireless side of the network when it comes to security because Wi-Fi has no physical fences. After all, a war-driver can detect your SSID and launch an attack while sitting out in the parking lot.

But in a world of insider threats, targeted attacks from outside, as well as hackers who use social engineering to gain physical access to corporate networks, the security of the wired portion of the network should also be top of mind.

So, here are some basic security precautions you can take for the wired side of the network, whether you’re a small business or a large enterprise.

1. Perform auditing and mapping

If you haven’t recently, you should do some auditing and mapping of your network. Always have a clear understanding of the entire network’s infrastructure, for instance the vendor/model, location, and basic configuration of firewalls, routers, switches, Ethernet cabling and ports, and wireless access points. Plus know exactly what servers, computers, printers, and any other devices are connected, where they are connected, and their connectivity path throughout the network.
