I was made aware of an excellent on-line service for testing the effectiveness of your firewall courtesy of Steve Gibson’s very informative Security Now! podcast (Episode 105). The name of the site is Firewall Leak Tester. The site’s developers describe the service thusly:
“This website, on one hand, enables you to test your software personal firewall thanks to different test programs (‘leaktests’), and on the other hand, shows a global vulnerabilities view of the most common personal firewalls in a summary page. Firewall Leak Tester provides also documentation and advice to improve your security dramatically.”
Nineteen (19!) tests are linked from this master resource. This is definitely a recommended service for the IT professional double checking their corporate firewall setup, computer enthusiast learning about how easily computer systems can be penetrated, or home PC users concerned about their privacy and security.
