Users should also note the “Package Details” tab, which allows users to see how KBs are connected, and which KBs replace previous ones.

This searchable resource provides information about KBs and allows users to download KBs as well. Users can learn which KBs are mapped to which Windows Version via the Microsoft Support resource. Here, users can connect all KBs related to a specific Windows Version.Users can learn which KBs are mapped to which Windows Version via the Microsoft Support resource. This resource helps users learn more details about specific KBs, in this case below, the November 2021 Monthly Rollup.

WINDOWS CRITICAL UPDATES UPDATE

Microsoft’s Security Update Guide information, including a KB article and CVE. From here you can download an Excel spreadsheet containing this information. Users can download the guide and map affected products to articles (KBs) and understand the impact of vulnerabilities, their severity as determined by Microsoft, and the CVE (Common Vulnerabilities and Exposures) number.

MSRC (Microsoft Security Response Center)Įvery Patch Tuesday, the MSRC publishes a Security Update Guide where users can find release notes for the KBs. The following resources are available from Microsoft, and were useful during our research as we tried to understand the relationships between specific CVEs and the KBs that remediate or mitigate them. Windows Version – a reference to a specific Windows operating system, service pack, and build: Each Monthly Rollup addresses new security issues for a specific product and will include updates that were previously released.īelow is an illustration of KBs for Windows Server 2012 R2 showing connections between Monthly Rollups and Security-Only Updates. Monthly Rollups (MR) are cumulative security and reliability updates. Security-Only Updates (SO) contain security updates for the month in which they are released, and each update is product-specific. There are two main types of updates (as explained in Microsoft Docs): KBs can be found using the systeminfo command on a Windows machine:

Updates are enumerated “KB123…” and are not sequential, which can lead to confusion when trying to determine patch levels and completeness.Įxample for non-sequential KBs (Here, in Windows 10 build 19044). Security updates start with the letters KB and refer to a specific Knowledge Base article each KB contains a number of updates and patches.

Knowledge Base (KB) – Microsoft KBs are a repository of articles describing issues affecting Windows and other Microsoft products. This predictable update cycle has been the centerpiece of vulnerability management programs for almost 20 years, allowing users to build routines around patching Microsoft vulnerabilities. Patch Tuesday – Since October 2003, Microsoft has published security updates across its product lines on the second Tuesday of every month, known as Patch Tuesday. Glossaryīefore we dig into the specifics of what we found, it’s important to understand some terminology. We will describe these challenges and walk through the journey of collecting data from different sources, building a dependency flow of updates, and eventually listing all remaining vulnerabilities on a host based on the list of installed updates. In other words, to determine which vulnerabilities are resolved given a list of installed patches.ĭuring our research we found this task difficult because of different complexities in the Microsoft update process. In these cases, IT administrators will still want to know based on the installed updates on a host, what vulnerabilities remain unpatched. For example, industrial networks are often not managed, and are isolated from the online update services, meaning that many computers are left unpatched and vulnerable. However, there are many environments in which that is not the case. That means most users are safe because they have an up-to-date version of Windows. Microsoft uses its monthly Patch Tuesday updates to automatically secure many Windows devices from those vulnerabilities. That makes Microsoft’s Windows operating system - the leading desktop operating system by market share - a high-profile target, with a constant stream of vulnerabilities published regularly. This happens at an even faster pace in popular platforms that are appealing to researchers and attackers alike.

Security vulnerabilities are regularly published by the dozens, and software vendors are in a constant race to issue updates that patch or mitigate them.
