Early Launch Antimalware
Another key security feature of Trusted Boot, supported by Microsoft Windows 10 and motherboards with an Unified Extensible Firmware Interface (UEFI), is Early Launch Antimalware (ELAM). Used in conjunction with Secure Boot, an ELAM driver can be registered as the first non-Microsoft driver that will be initialised on a workstation as part of the boot process, thus allowing it to verify all subsequent drivers before they are initialised. The ELAM driver is capable of allowing only known good drivers to initialise; known good and unknown drivers to initialise; known good, unknown and bad but critical drivers to initialise; or all drivers to initialise. To reduce the risk of malicious drivers, only known good and unknown drivers should be allowed to be initialised during the boot process.
The following Group Policy setting can be implemented to ensure only known good and unknown drivers will be initialised at boot time.
