8. Security > 76. Test Your Security with Shields UP!

Test Your Security with Shields UP!

Head to this web site for a thorough, free check of your PC’s vulnerabilities.

Do you really know how secure your PC is from intruders? Probably not. But there’s a free online tool that will probe your PC for online security vulnerabilities and report to you on the results.

The Shields UP! site is run by the Gibson Research Corporation, and it tests your machine, trying to make connections to a handful of the most well-known and vulnerable Internet ports on your PC. The site runs two tests, reports to you on the results, and then explains what the reports mean—where you’re vulnerable and how serious those vulnerabilities are. It also has a great deal of useful information about Internet security, as well as free and for-pay security software you can download. Visit the site at http://www.grc.com. You might have to do some clicking around to find the tests, but keep clicking Shields UP! and you’ll eventually get there.
