If you have WSUS listed as an update source, you should plan to create an Automatic Approval rule for SCEP definitions.
While it's true that WSUS is mostly controlled by Configuration Manager, it will still function happily as a standalone WSUS instance for the purposes of making SCEP definition updates available. Updates distributed from WSUS Configuration Manager admins generally stay out of the WSUS console, except to periodically perform a WSUS cleanup or other maintenance.Updates distributed from Microsoft Malware Protection Center MMPC should always be last in your source list, as the payload from this location will be much larger.Of the two Microsoft hosted fallback locations, this is ideal as it results in the smallest payload delivered to the client. It is useful for clients that are off of your network for a while, unless you are set up to manage internet based clients or are using DirectAccess. Updates distributed from Microsoft Update This one sounds fairly obvious.Also, if out of date definitions are left on the UNC share, it can cause the clients to fail checking any further sources in the fallback list. A few drawbacks of this option are that the UNC file share is not populated automatically and it does not take advantage of binary delta differentials. This can leverage existing DFS infrastructure if it exists. Multiple UNC paths can be specified, as seen below. This option modifies both the FallbackOrder key and the DefinitionUpdateFileShareSources key. This can be seen a few screenshots above. Updates from UNC file shares If we select this option, we must also define the UNC paths in the definition updates section of the antimalware policy.Believe it or not, SCEP cannot use CM as an update source location for definitions, which is why this setting does not modify the FallBackOrder registry key. When this period expires, it will attempt to pull definitions from the order defined by policy and stored in the Fallback registry key. This value represents (in minutes) the amount of time the SCEP client will 'sleep' and wait for CM to bestow signatures upon it. You can modify this value in your Antimalware Policy. By default, this is set to 4,320 minutes, or 72 hours. Updates distributed from Configuration Manager Selecting this option sets a registry value called AuGracePeriod in HKLM\Software\Policies\Microsoft\Microsoft Antimalware\Signature Updates.If none of the sources have definitions available, the SCEP client will return an error. The SCEP client will check each update source in order until it locates a source that has available definitions. When the SCEP client definitions become too far out of date, or if the end user clicks Update in the UI, the SCEP client looks for a FallBackOrder registry key in HKLM\Software\Policies\Microsoft\Microsoft Antimalware\Signature Updates. You've got a few options here, so let's discuss what they actually do. You could have quite a few Antimalware policies, but I'll be working with the default policy in my screenshots today.Īt this point, those who are familiar with these settings may be ready to skip ahead. If you're not familiar with this, navigate to Assets and Compliance, Endpoint Protection, Antimalware Policies.

What happens if the CM Software Update Agent fails to install definitions? What happens if the end user forces an update by pressing the update button in the SCEP user interface? In these situations, we'll need to better understand the setting for definition update sources in the Antimalware Policy. Make Updates Available Outside of Configuration Manager This will certainly get the updates deployed, but there is more to consider.
In my observations, the most common solution that administrators use is to create an ADR (see below) and let it run on a schedule: If your company has deployed or is planning to deploy SCEP, you will certainly have to plan to deploy definition updates. Escalation Engineer, for helping me with this blog. Huge thanks to my colleague Jeramy Skidmore, Sr. For my first blog, I want to introduce you to updating System Center Endpoint Protection (SCEP) definition updates.
