In this digital age, internet makes our life a lot easier than before. It has given us many things for free like email service, information and much more stuff. With every good thing, there are some bad things associated. In case of internet, security is a problem. If you computer is not connected to internet, its safe like a locker but as soon as you connect to internet, its open to world. Anyone with a little knowledge of networking and hacking can get into your system from any part of the world and steal your data. Trusted Internet connection is only available with those sites who use digital certificate and secure socket layer on servers but not every site has this feature. Sites with https link are secured and you know not every site you browse have that “s” after http. So people are looking into your system is a problem, ok but there is one more and that is as soon as you connect to internet, several applications try to access internet by connecting to some server. Now trusted applications are fine but you never know when an unknown and harmful piece of program (Trojan) connects to net and cause disaster in your computer. Simple and effective protection to this entire problem is to use a good antivirus and firewall. Some people don’t give importance to firewall but it’s a must have thing for every computer connected to internet. I personally use Comodo firewall which is very effective in keeping your computer safe from hack attempts and any kind of intrusion. The firewall learns with time and asks you every time it finds an unknown application trying to access internet, if you find it fishy, you can simply block it. All hack attempts are effectively blocked by Comodo firewall giving you peace of mind. For personal use, this firewall is free and I recommend every home user to try it.
