My Top 3

Windows firewall, a security software that help windows users inspects network traffic passing with built-in network exceptions to allow connections from machines on the local network. Using firewall software on your computer and laptop is a must to identify which applications on the computer are creating security risks.

If a worm infects your system and attempts to open your computer to the world, the personal firewall will prompt you to confirm the new application or to prevent its use. Your personal firewall may be your first warning that a malicious program is attempting to use the network! Plus more, Windows Firewall can protects your computer by preventing unauthorized users from gaining access to your computer through the Internet or a network.

However, the default Windows firewall ( Internet Connection Firewall ) that install on Windows operating system has limitation of security protection or less user friendly compares to third party firewall software.

Two major disadvantages to using default Windows firewall ( Internet Connection Firewall) :

1. default Windows Firewall does not restrict outgoing traffic from your computer or restrict applications from using your Internet connection. This means that if have a virus , Internet connection firewall will allow your applications to send data to the Internet without your permission.

2. when you boot your computer, Windows will enable your Internet connection before it enables the built-in firewall. This means that if someone attempts to hack your computer or port scan you while your computer is booting, your computer will be available on the Internet before the firewall starts up. This creates a limited opportunity for your computer to be hacked. Though this risk is mitigated by the short length of time between your Internet connection being active and the firewall starting, it is still a risk to take into consideration.
