Detect and Install Software Updates Using Secunia Personal Software Inspector (PSI)
Although large vendors such as Microsoft and Apple have an established infrastructure in place to alert users about patches and to install them, few other vendors have such a mechanism. This makes it necessary to regularly visit all the Web sites of all the installed software on a system to stay current on all software updates. To make the process more manageable, online software scanners were created that can compare all applications on a computer with a list of known patches from the different software vendors and then alert the user to any applications that are not properly patched, even providing links to the vendor’s Web site to download and install the patches. Now online software scanners can even automatically install the patches when a missing patch is detected. The Secunia Personal Software Inspector (PSI) can take an inventory of the applications and version numbers running on a computer and then compare them with the Secunia site several times a day to see if a new patch has been released; if it has, the patch is silently downloaded and installed. In this project, you will use Secunia’s PSI to identify and patch any applications that have not been updated.
