By being launched first by the kernel, ELAM ( Early Launch Antimalware) is ensured to be launched before any third-party software, and is therefore able to detect malware in the boot process and prevent it from initializing.
Check
The default behavior is for Early Launch Antimalware - Boot-Start Driver Initialization policy is to enforce "Good, unknown and bad but critical" (preventing "bad").
If the registry value name below does not exist, this a finding.
If it exists and is configured with a value of "7", this is a finding.
Possible values for this setting are: 8 - Good only 1 - Good and unknown 3 - Good, unknown and bad but critical 7 - All (which includes "Bad" and would be a finding)
Fix
Ensure that Early Launch Antimalware - Boot-Start Driver Initialization policy is set to enforce "Good, unknown and bad but critical" (preventing "bad").
If this needs to be corrected configure the policy value for Computer Configuration >> Administrative Templates >> System >> Early Launch Antimalware >> "Boot-Start Driver Initialization Policy" to "Enabled” with "Good, unknown and bad but critical" selected.
