How secure Your Wifi

Help secure your wireless network
If you don't secure your wireless network, everything on your network, including personal information, could be accessed by strangers.


Set you administrator password: – The administration password set by the manufacturer are easy to hack, so change this immediately, and choose your own password. Don’t use your name, date of birth, names of your pet/child or their date of birth, and try to include some random numbers and non-alphanumeric symbols too. This will make it harder for a hacker to guess.

 Switch off SSID (Service Set Identifier) broadcasting on the router:- This tells devices that your network exists, so switching it off will stop it from broadcasting its existence. It’s much harder to hack something invisible!

 Enable encryption in your connection settings:- If your device supports it, then WPA encryption is best. If not use WEP encryption.

 Don't use sites that stick to or revert to HTTP :-  Sites that log you in over unencrypted HTTP (horrors!) or revert to HTTP after SSL login are prime targets. Anyone that can intercept that traffic can easily record and reuse the cookie, which identifies you on subsequent requests, thereby hijacking your authenticated session. Known-vulnerable sites include Amazon, Basecamp, bit.ly, CNET, Evernote, Facebook, Flickr, Foursquare, Google, PayPal, Twitter, Windows Live, Wordpress, and Yahoo. But avoiding this list is nowhere good enough. Many other sites are vulnerable and can be imported into Firesheep to grab those cookies too.

 Avoid leaking cookies over HTTP :- Some websites try to do the right thing, but fall short. Specifically, servers must set a Secure flag to tell browsers to only send cookies over SSL. But sites that don't set this flag (such as Dropbox and Slicehost) let cookies "leak" over HTTP.  

Defend your computer :- Keep all software current (including your web browser) with automatic updating. Make sure that your firewall is turned on and use antivirus and antispyware software from a source that you trust, such as Microsoft Security Essentials. (Don't forget to watch out for fake alerts for security software.)
