On the wireless side you have at least WPA2-Personal (PSK) that’s easy to deploy.Īlthough MAC address filtering can be bypassed by a determined hacker, it can serve as the first layer of security. One major security issue of the wired side of network is the lack of a quick and easy authentication and/or encryption method people can just plug in and use the network. Disconnect unused Ethernet ports, physically or via switch/router configuration, especially those in the public areas of the building. Verify that Ethernet cabling is run out of sight and isn’t easily accessible the same with wireless access points. Then ensure all wiring closets and/or other places where the network infrastructure components are placed have been physically secured from both the public and employees. But if that Ethernet port wasn’t visible or at least disconnected, then that wouldn’t have happened.Įnsure you have a good building security plan in place to try and prevent outsiders from entering. For instance, maybe they plug a wireless router into an open Ethernet port, giving them and anyone else nearby wireless access to your network. Without strong physical security of your building and network, a nearby hacker or even an employee could take advantage of it. Just as you need to protect against hackers, bots and viruses, you need to protect against local threats, too. Physically secure the networkĪlthough often overlooked or minimized, the physical security of the network can be just as crucial as say your Internet facing firewall.

Ensure the basics are taken care of, such as OS and driver updates, personal firewall are active, the antivirus is running and updated, and passwords are set. Next take a look at all the computers and devices connected to the network. + ALSO ON NETWORK WORLD 8 free Wi-Fi security tools + Login to the components to ensure default passwords have been changed, review the settings for any insecure configuration, and look into any other security features or functionality you currently aren’t using.

Check for firmware or software updates on all network infrastructure components. Once you have a basic network audit and map complete, consider diving deeper. They can scan the network and start to produce a network map or diagram. For larger networks you might find auditing and mapping programs useful. If you’re working with a small network with just a few network components and a dozen or less workstations you might just manually perform the audit and create a visual map on a sheet of a paper. Maybe you’ll run across an incorrectly configured firewall or maybe physical security threats.

Plus know exactly what servers, computers, printers, and any other devices are connected, where they are connected, and their connectivity path throughout the network.ĭuring your auditing and mapping you might find specific security vulnerabilities or ways in which you could increase security, performance and reliability. 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. If you haven’t recently, you should do some auditing and mapping of your network.
