Many People get very excited about WiFi and after purchasing leave many patches in the security measures of the WiFi. Many folks leave the password and username as the same default.(I wont mention the default username and password..lol)
I note down some important steps to be taken care while setting up the security measures for your WiFi.
1. Change the Default Settings of WiFi :
Mostly Wi-Fi home networks is an access point or router. To setup the configuration a web page url is provided and to login the password.This is the right only for the admin.But for the default equipment the password provided is pretty simple and i am sure by now you people must have even guessed it.Lol..!!
Change the password immediately as soon as possible.
2. Ensure that WEP/WPA is enabled
Wired Equivalent Privacy (WEP) is a deprecated algorithm to secure IEEE 802.11 wireless networks. It uses Shared key technique for authentication.
The 802.11i standard addresses many of the security issues of the original 802.11 standard. While the new IEEE 802.11i standard is being ratified, wireless vendors have agreed on an interoperable interim standard known as Wi-Fi Protected Access (WPA).
3. Enable MAC Address Filtering
MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network.
While giving a wireless network some additional protection, MAC Filtering can be circumvented by scanning a valid MAC and then changing the own MAC into a validated one. This can be done in the Windows Registry or by using commandline tools on a Linux platform.
There are some other methods to secure Wifi.Which i would be discussing in my next post.
