In the last post, we covered some advanced techniques for making your wireless network even more secure. We discussed the importance of physical security and location of routers, the benefits of enterprise encryption, and advantages of using an intrusion detection and prevention system. Today we’ll cover even more techniques that can help keep your network secure and your computer free of viruses and malware.
4. Create Usage Policies
Here are a couple of example policies you can implement to improve the security and integrity of your wireless network.
· List devices that are authorized to access the wireless network. Explicitly name which computers and mobile devices can gain access to the network by enabling MAC address filtering on the network router.
· Use the 802.1X authentication you set up in step #1 of this two-part series to develop a list of authorized personnel usernames and passwords that can access the network.
· Make sure only the IT department can set up wireless routers. This prevents someone from plugging in an AP from home to extend the signal.
· If you’re concerned about data being compromised while a company device is connected to a wi-fi hotspot or home network, implement rules to govern the wi-fi connections the device is allowed to use. You can impose network filters, or a VPN connection back to the company network to protect internet activity and remotely access files securely.
5. Use SSL or IPsec on top of Wi-Fi Encryption
It’s possible to double-encrypt your network by using an SSL or IPsec layer over your normal WPA authorization. This also helps secure wired communication to prevent eavesdropping or outsiders tapping into the network through a physical port.
By implementing these 5 tips you should be well on your way to a hack-proof network and achieving greater security than you would with the basic networking measures. This should help you keep your computers and network free from viruses and cyber attacks and help you avoid expensive pc and laptop repairs.
