In my last post, I urged readers to patch weak applications. How do you know which ones to patch? The hard way to do it would be to go through your program files and open each application, check the version, and then see if there is an updated version at the vendor’s website.

Or you can use F-Secure’s HealthCheck application here. It automatically enumerates your programs and tells you which ones are unsupported, out of date, insecure, and unpatched. When possible, it provides a way to fix the these apps too. Unfortunately, it only works on Windows hosts using Internet Explorer 6.x or later. After running the application, I realized that my version of Java was outdated. Being a security expert, I always religiously patch my apps, so I could have sworn it was already up to date. If you are surprised by the results you found after running the HealthCheck, let us know below, and Happy Patching!
