WiFi based internet access is now becoming more popular in India as it’s gaining popularity in India attackers are using these networks to perform their activities on internet. In recent days terrorists used WiFi networks to access the internet and send the terror mail. Accessing internet through WiFi instead of broadband make more vulnerable to hackers. Following some simple steps we can save our WiFi networks.

Change the WiFi Router Default Password: Most WiFi routers comes with preconfigured default passwords and most of the time attackers know all default passwords. Always change the default password of your WiFi router. Accessing internet through a password protect WiFi router makes you less vulnerable to hackers.

Disable SSID Broadcast: A service set identifier, or SSID, is a name used to identify the particular 802.11 wireless LANs to which a user wants to attach. Configure your WiFi router so that it  won’t broadcast your SSID. Turning off SSID broadcast will keep casual attackers away from your WiFi  networks. Just turing off SSID broadcast will not solve your problem because most manufactures ship their routers with same generic SSID. To solve this issue change the SSID to a different name than the default like your unique name.

Remember, though, to turn this feature back on when you return to the office.

Use Wireless Encryption: Wireless Equivalent Protocol (WEP) and WiFi Protected Access (WPA) are two wireless encryption standards available. WEP is now outdated, currently A 128-bit WEP is an updated, more secure version of the original WEP.WPA is the current, common encryption standard you should probably be using — though, of course, you should use something stronger as soon as it becomes available to you. OpenSSH is an excellent choice for providing secure communications between computers on the same network, as well as across the Internet. Using encryption to protect your wireless network does not protect any communications that leave the network, so encryption schemes like SSL for dealing with e-commerce Websites is still of critical importance.

Use secure and anonymous Web surfing techniques: This is very important if a VPN service is not available or the VPN will not set up correctly. There are various Web services that provide SSL VPN solutions by creating an encrypted tunnel from the notebook to their secure server. This eliminates a whole slew of possible issues. Some of the more preeminent services are Megaproxy and TOR.

Monitor your access points: Chances are, there are multiple wireless networks anywhere you’re trying to connect. These connections are all access points, because they link into the wired system that gives you Internet access. So how do you make sure you’re connecting to the right one? Simple—by configuring your PC to let you approve access points before you connect.

Make sure your firewall is activated: A firewall helps protect your mobile PC by preventing unauthorized users from gaining access to your computer through the Internet or a network. It acts as a barrier that checks all incoming information, and then either blocks the information or allows it to come through. All Microsoft Windows operating systems come with a firewall, and you can make sure it’s turned on.
