Test the security of your computer!

  • The Gibson Research Corporation (www.grc.com) has, amongst other things, some excellent free utilities which allow you to test the security of your computer. ShieldsUP! allows you to test your computer and firewall for any open ports which could be vulnerable to attack. LeakTest is another useful utility, allowing you to test the outbound program authentication on your firewall. All the utilities on the website also come with easy to understand explanations of what they are designed to test and why they are important.

Hi there. If this is the first time you are posting a comment it will not appear immediately, but needs to be approved. This is necessary in order to combat comment spam. However, once you have submitted a comment (which is subsequently approved) you do not need to go through this process again - the site remembers who you are and auto-approves your comments. Nifty eh? Anyway, sorry about the inconvenience that this may cause for your first comment post.
