Well, according to this Technet Page on Forefront Enterprise Protection (Which is the same product as SCEP, which is the same product as Security Essentials, etc., etc.), the following log locations exist for the product, which you could parse with some PowerShell for the information you seek:
%allusersprofile%\Microsoft\Microsoft Antimalware\Support
- Log files specific for the antimalware service
%allusersprofile%\Microsoft\Microsoft Security Client\Support
- Log files specific for the SCEP client software
%windir%\WindowsUpdate.log
- Windows Update log files, which include information about definition updates
%windir%\CCM\Logs\EndpointProtectionagent.log
- Shows Endpoint version and policies applied
%windir%\temp\MpCmdRun.log
- Activity when performing scans and signature updates
%windir%\temp\MpSigStub.log
- Update progress for signature and Engine updates
I also stumbled across the native cmdlets for SCEP, which you can list with: Get-Command -Module MpProvider
, but they wouldn't behave for me, I couldn't do an Update-Help
or find info about them on Microsoft sites... so I gave up. Maybe you'll have better luck - they seem to be basically the same as the cmdlets for Windows Defender.
