To Firewall or Not To Firewall….

If you have ever installed a fully featured Antivirus program, or another security program, you may of been presented with an option to install a firewall, thereby disabling the standard firewall built into Windows.

What is a firewall, and should we keep the Windows firewall, or use the 3rd party software firewall?

A firewall is a hardware of software application that blocks unauthorized access to a computer or network.  It also lets the right kind of access in or out, meaning you can still access the internet and applications you need.

For most small businesses and home users, a software firewall application is suitable.  For larger networks, or high security, a robust hardware solution may be the answer.

There are arguments for using or not using the built in firewall in Windows.

  • FOR – The windows firewall is automatically configured and turned on by default.  You don’t have to do anything to start it up.
  • AGAINST – Microsoft Windows is a huge target for hackers.  They are always looking for ways to find ways into the system.  It may be harder to attack a system with another software firewall running.
  • FOR – If you have a hardware firewall application, or the firewall setup on your router, it does not hurt to keep the Windows Firewall running on your individual computers.
  • AGAINST – A company that specifically makes security software is focused on the purpose of security.  A 3rd party firewall application typically provides greater protection, though it does require more interaction and configuration.

Whatever your decision is, having a firewall running on your computer(s) is a good idea.  There are thousands of viruses, worms, and other threats floating around in cyberspace.
