Are you Secure when you browse the web ?
I have a question today?
How fussy are you to which Wi-Fi signal you connect? i.e., connecting to an open or a secure Wi-Fi connection.
As we know that most of the Coffey shops and pubs allow you to use the free Wi-Fi open connections. Do you even think twice before connecting to a open Wi-Fi signal?
Please put some time to understand what is the risk involved in using an open Wi-Fi connection.
I know getting internet connectivity when your out and about will look like a blessing. However all your data and your laptop itself can be compromised by anyone connecting to open Wi-Fi connections.
Some people think that having a Anti-Virus program or an Firewall enabled laptop will keep them safe, what they don’t know is when they setup the connection with an open Wi-Fi connection they have already established a trust relation with that router.
Windows 7 gives warning to the user that its very risky to connect to a Open and un-secure Wi-Fi networks yet most of the people I know still connect anyway.
Moreover I know a couple of friends who bought a wireless router and started using it without setting up of security key or changing the default admin password.
Eventually someone else started using their network; they only realized this after they felt that their connection became slow.
This could have been worst as people can capture all the packets and get the critical information like online banking information, CC numbers etc.
The truth is even if your using secure Wi-Fi connection, wireless technology can still be very easy to compromised, how ?
Check out for yourself Googleit – how to crack Wi-Fi network and you will get the answer.
However we can avoid this just by making sure we do not use simple name or dictionary words as a passphrase.
Always use complex passphrase /WEP/WPA2 keys and make sure you have a key which is at least 10 to 12 characters long.
Now let’s get to the point How to secure Your wireless network ?
Change Your network name and Your router login information
Simple job just login to the router using the details from Manufacture. Usually found at the back on the router long and change the Name of the network and login information or at least the password.
Secure Your Wi-Fi network:
If you do not secure your network it will be open for anyone who can get your wireless signal.
WEP (Wire Enabled Protection) this should only be used if you have old laptop that does not support the advanced encryption. If you are using this make sure you use 128 bit encryption.
WPA 2 encryption is the best so far, However I suggest you keep a long passphrase and complex at the same time.
Hide Your network name (SSID)
Although most people don’t do this, but I strongly suggest you to hide the SSID. Simple logic if they can’t find your Wi-Fi signal you will be less vulnerable to get hacked.
Enable Software and Hardware Firewall:
Let me explain Software firewall is the firewall built into the Operating System i.e., Windows Vista or Windows 7 just enable it.
Hardware firewall ah might be new to some of us, but most of the routers built today even the cheapest one has a firewall program built into them. So all you got to do is login to the router using your admin login and enable it.
Hope you find this post useful feel free to comment if you ever used open / un-secure Wi=Fi.
