T1177: LSASS Driver Mitigation
On Windows 8.1 and Server 2012 R2, enable LSA Protection by setting the Registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\RunAsPPL to dword:00000001. [1] LSA Protection ensures that LSA plug-ins and drivers are only loaded if they are digitally signed with a Microsoft signature and adhere to the Microsoft Security Development Lifecycle (SDL) process guidance.
On Windows 10 and Server 2016, enable Windows Defender Credential Guard [2] to run lsass.exe in an isolated virtualized environment without any device drivers. [3]
Ensure safe DLL search mode is enabled HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SafeDllSearchMode to mitigate risk that lsass.exe loads a malicious code library. [4]

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
