So in one of the first post we talked about WiFi and the magic sensation when the WiFi is open! And I hope you remember we said that was one of the more easiest way to lose your information. Well, technically you exchange your data for free WiFi.

Here we are going to talk about the importance of the security in Wireless networks. Wireless security is about prevent unauthorized access to the computers using wireless networks. Let´s talk about WEP (Wired equivalent privacy) and WPA (WiFi protected access). WEP is a weak security standard and nobody should be using it in this moment. The password it uses can often be cracked in a few minutes with a basic laptop and available software tools. You probably have done this when you use the “WiFi Hacker” App from the Android store. Was outdated in 2003 by WPA, which was a quick alternative to improve security over WEP.

The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device that encrypts the network with a 256-bit key; the longer key length improves security over WEP.


The hackers (black hat) have found the wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks. As as result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources. Wireless intrusion prevention systems and wireless intrusion detection systems are commonly used to enforce wireless security.

So a good way for enterprises to actually protect themselves even with WPA2 is to use the Enterprise version of WPA, which requires a RADIUS server, that can be a local server of can be on the internet, I used IronWifi for my final project of “Wireless
