Facebook adds more security by going HTTPS

by Mahesh Kukreja on January 27, 2011

Facebook has finally improved it’s security by implementing the HTTP Secure (HTTPS) protocol.

HTTPS is a combination of the HTTP and SSL/TLS protocol which provide encrypted communication and secure identification of a web server. HTTPS is often used for transmitting login information, payment information (like Credit Cards, bank account info, etc).

Facebook goes HTTPS

You must seriously consider enabling this option if you frequently use Facebook from public Internet access points found at airports, schools or restaurants. Without HTTPS, hackers can easily sniff your data if you’re accessing public Wi-fi.

The option is on Account Settings page of Facebook. If you don’t see it now, don’t panic, you’ll see it in the coming weeks.

But many applications on Facebook are not yet supported by the HTTPS protocol. So, we have to wait till Facebook implements this feature all-over.

Here is an official post on the Facebook blog.

Wi-fiWireless security is of major concern at this time. Terrorists might use your unprotected Wireless network for sending e-mails and/or Cyber Terrorists can use it for hacking into Government websites/networks. Your IP address will be traced by the Cyber Police and you’ll be in unnecessary trouble. Very less people actually use Wireless security to protect their networks.

Even your neighbors can use your unprotected wireless network and access your bandwidth.

The owners either ignore the wireless security completely or they don’t know how to work around to set up wireless password.

Here’s  a basic tutorial to set wireless security on Netgear WGR614v9 wireless router. For other routers like Linksys, the procedure is almost same with certain navigation changes.

Step 1: Open up your favorite web browser and access the router (http://192.168.1.1 or the Default Gateway address if the router’s default IP was changed).

Step 2: Log in the router (User Name = admin and Password = password, unless you changed it. The username can be different on different routers).

Step 3: Navigate to Wireless Settings on the left side.

Netgear Wireless Settings

Under Security Options, select WPA2-PSK [AES] (Want to know what is WPA2 PSK? Head up here). WPA2-PSK is better than WEP (WEP can be hacked easily under 5 mins).

After that, type your password in the Passphrase text box, and then click on Apply. This is the password you’ll be using to connect your Laptop/Wi-fi device to the network.

That’s it! Was it that difficult?

Step 4: (Follow these steps if you haven’t yet changed the default login password for the router)

Netgear Admin Password

Click on Set Password under Maintenance. Enter your old password (default: password), and your new password. And click on Apply.

You’re done! If you have any questions, feel free to ask in the Comments section below.
