- Network administrators should choose to add encryption to wireless networks to protect communications against eavesdropping. Wireless encryption is a best practice for network security. Encryption hides the true content of network traffic from those without the decryption key. It takes an insecure communications technology, radio waves, and makes it secure. The original approach to solving this problem was a technology known as Wired Equivalent Privacy, or WEP. WEP was used for a long time, but it's now known to suffer from some very serious security vulnerabilities. These issues are so significant that security professionals no longer consider WEP secure, and WEP should never be used on a modern network. A newer technology called Wi-Fi Protected Access, or WPA, replaced WEP all the way back in 2003. This first version, just called WPA, used the Temporal Key Integrity Protocol, TKIP, to add security that WEP didn't have.…
