Summary
This rule aims to detect attempts to disable Protected Process Light (PPL) protection for the Local Security Authority (LSA) using the Windows Registry Editor (`reg.exe`). PPL is a security feature in Windows designed to enhance the protection of critical system processes such as LSA, which is responsible for enforcing security policies. Specific command-line activities involving `reg.exe` are monitored for indicator patterns suggesting an alteration of the LSA configuration by setting the `RunAsPPL` value to `0`. Detection is confirmed when the detection conditions, which include both the presence of the `reg.exe` executable and specific command-line arguments related to modifying the LSA settings, are met. The use of these command-line arguments to disable PPL could indicate unauthorized attempts to compromise the security of system processes.
