A parctical approach to secure WLANs for SOHO and enterprises

Though several security solutions for WLAN are available in the market and we can mix them together to strengthen the security more, but as data packets are transmitted in the air, it is always insecure. In case of a most secured SOHO setup that is proposed here, the worst case can be: A hacker have to intercept the packets to break the WPA2/WPA key first. In this case, he needs to use the dictionary attack using rainbow table and selecting a complex key pass-phrase will make the hacker to give a lot of effort. A proper selection of pass-phrase may even lead the hacker to use a server grade processing setup to break the key. After the successful breaking of the key, still the hacker will have to scan for a valid MAC that is associated with that AP and will have to change his MAC with the newly collected one. In a low user/traffic concentrated WLAN, collecting of around 50,000 IVs will become very time consuming for the hacker.
