System Center Endpoint Protection Definition Updates

Question

Hi can anyone advise deploying definitions via SCCM 2012 and selecting the source as being "Updates distributed from Configuration Manager" does that mean each client will go to the Primary Site to get updates? Or by using ADR will it ensure that
definitions come via distribution points?
Also another question, as sccm 2012 is not rolled out to all sites yet, and will be deploying unmanaged clients, when I deploy the SCEP client offline un-managed with a policy file, is there a way then later to change policy on the client by command line?

Answer 1

You could configure updating SCEP in many ways, including:
Updates distributed from Configuration Manager – This method uses Configuration Manager software updates to deliver definition and engine updates to computers in your hierarchy.
Updates distributed from Windows Server Update Services (WSUS) – This method uses your WSUS infrastructure to deliver definition and engine updates to computers.
Updates distributed from Microsoft Update – This method allows computers to connect directly to Microsoft Update in order to download definition and engine updates. This method can be useful for computers that are not often connected to the business network.
Updates distributed from Microsoft Malware Protection Center – This method will download definition updates from the Microsoft Malware Protection Center.
Updates from UNC file shares – With this method, you can save the latest definition and engine updates to a share on the network. Clients can then access the network to install the updates.
