Pros And Cons Of Patching With WSUS

Windows Server Update Services (WSUS) is a widely used tool that helps businesses automate their Windows patching process. Distributed by Microsoft, WSUS was designed to alleviate the pain and difficulty of patching manually.

For Windows environments, WSUS seemed like a simple solution to the patching process, however it has been plagued with usability issues since it was introduced. As organizations grow more complex (work from home, cloud, BYOD) and have more functionality needs from their patching solution, WSUS can become an outdated solution. So what are the pros and cons of patching with WSUS?

Pros of WSUS

Cost: WSUS is a free tool that is installed as a role on Windows Server, so businesses of any size can take advantage of its features. For smaller companies who aren’t able to utilize Microsoft’s System Center Configuration Manager (SCCM), WSUS provides some patching automation capabilities at no upfront cost. However, companies evaluating WSUS should keep in mind the hidden costs of the system, such as time spent on troubleshooting and cost to acquire and use other tools for non-Windows operating systems and third party applications.

Works with Windows Systems: Since WSUS is built by Microsoft, it will not have conflicts with Windows systems and, when configured correctly, can patch these systems semi-automatically. For those with Microsoft-only infrastructure, WSUS reduces the manual labor behind patching and tracks updates so SysAdmins can see what updates have been applied to each machine.

Cons of WSUS

Difficult to setup and configure: The initial setup of WSUS can be time-consuming as there are multiple system requirements that have to be met before it is installed, and configuring the system to automatically check for and apply updates can be both time consuming and complex. WSUS sometimes fails to sync on certain machines, leaving technicians to spend hours identifying the root cause of the problem and resolving it.

Update Issues: There have been long-standing reports of WSUS failing to properly update on patch status for all workstations and servers. Updates may not be installed consistently across an infrastructure, and some machines will report being 100% up to date on patches when they are still missing critical updates. If SysAdmins are not vigilant in tracking patch status and failed updates, WSUS will leave you vulnerable when you think you’re patched.

Doesn’t work with mixed-OS environments: WSUS is by design a Windows-only solution, which limits its usefulness as infrastructures increasingly include non-Windows operating systems.

Limited Ability to Patch Third-Party Applications: Third-party software, such as Java and Adobe, are easy targets for hackers as they often include vulnerabilities which have not been patched. WSUS only allows for patching of these applications through complex workarounds, and the update catalogs are not intuitive.

Lack of reporting: Infrastructure visibility is increasingly important as attacks become more costly and compliance becomes stricter. WSUS fails to provide adequate reporting on network-wide vulnerabilities, leaving SysAdmins to patch together reports from several sources and hope they have accounted for everything. This lack of reporting can lead to unpatched vulnerabilities going unnoticed and failed audits.
