How to secure your WLAN by Ashish Mahajan
The impact wireless technology has had in few years on corporate world is remarkable. Considering the fact how wireless technology is used today, serious security vulnerabilities have also been created.

To minimize the impact consider the following steps.

Enable WEP or Wired Equivalent Privacy
WEP has two variants 64 bit WEP you need to know the 10 digit alphanumeric network key and 126 bit WEP that has 26 bit digit alphanumeric network key. Rotating keys weekly is a good practice as a network administrator also802.1X allows you to rotate keys automatically with the user-defined intervals that can be hourly, weekly or monthly. Hackers can easily detect the keys set using WLAN sniffers.Better way to protect your wireless network is to have WI-FI protected Access enabled as WEP is a system for encrypting your data to keep it private from unauthorized user., it is advised to have WEP enabled even thought it's easy to break.

WPA provides much better security
It is not only limited to 0-9 and A-F as they are with WEP. Modern Wireless hardware and operating systems provides an inbuilt capability of WPA support. Recent Wireless hardware has more advanced encryption known as WPA2.No questions asked that WPA fix the flaws in WEP but still subject to DOS (Denial of Service attack) attacks.

Don’t broadcast your SSID
WLAN access points automatically broadcast the Network’s name or SSID (Service Set Identifier).This way you locate a WLAN without having to know what it is called, but it will also be visible to any other wireless device in range. Turning off the SSID broadcast for your network will make it invisible to your neighbours and hackers though it will still be visible through WLAN sniffers.

TKIP
Temporary Key Integrity Protocol (TKIP), works on top of WEP offering stronger security than WEP and increased assurance that the data will not be compromised. TKIP has an enhanced security with the new encryption algorithm that has ability to covers the security flaws in WEP to provide better security. This protocol makes it very hard for the Hackers to break into. In TKIP encryption key itself is encrypted which makes it very hard for the hackers to capture and then decrypt the encrypted key. Furthermore, it also provides constantly changes the encryption keys making them harder for wireless hackers to capture them. In case Hackers managed to break the encrypted key, the odds are rather high that the key would have already changed again. TKIP offers the robust solution for any Wireless network.
