"Test Your Computer Fire Wall With ShieldsUP!"

by LifeHacker

"The best way to determine if your computer's (or router's) firewall is working and optimized is to effectively try to penetrate it. Browser-based utility ShieldsUP! tests your firewall for vulnerabilities and kinks in your computer's defense.

After you give ShieldsUP! permission to run tests on your computer and choose a test type, it looks for weaknesses and openings that hackers and intruders can use to attack your machine. You can test in five different categories: file sharing, common ports, all service ports, messenger spam, and browser headers. When a test completes, ShieldsUP! will displays the results and offer suggestions for how you can improve your security, with detailed explanations. It's a good tool for evaluating your computer's security and determining whether you need to amp up your computer's defenses.

We actually mentioned ShieldsUp! in passing in our previous guide to portscanning your computer for security holes, but it's a solid tool worth highlighting on its own. If your port-scanning interest has been piqued, be sure to check out our previous guide for a more thorough examination of the subject."
