Understanding The Different 'Types' Of Patches Within Protect

Version 3



    The purpose of this document is to provide more information about the different patch types offered within Protect.



    There are 5 different patch types within Protect, they are as follows

    • Security Patch
      • A Security patch addresses a specific security vulnerability. They are accompanied by a Security Bulletin.
    • Non-Security Patch
      • This is a non-critical update released by vendors to enhance functionality and/or include minor changes to the application.
    • Security Tools
      • Security tool patches are patches for Malware tools and Microsoft Security Advisories. Security Advisories are a way for Microsoft to communicate security information to customers about issues that may not be classified as vulnerabilities and may not require a security bulletin. Each advisory is accompanied by a Microsoft Knowledge Base Article to provide additional information about any changes or updates being delivered with the advisory’s release.
    • Software Distribution
      • A software distribution patch is a full installer of an application. Only supported applications have a software distribution patch.
    • Custom Action
      • Enables you to perform custom actions even if you are already fully patched. It does this by scanning for a specific QNumber and patch (QSK2745, MSST-001) that will always show as missing on any target system. The process uses the temporary file Nullpatch.exe, which was specifically designed by Shavlik to run without making any changes.
