What is the difference between Intrusive Attaching and Non-Intrusive Attaching when debugging?

Question

In Core Debugger Concepts What is the difference between Intrusive Attaching and Non-Intrusive Attaching when debugging?

Answer 1

non invasive debugging has access to the process memory and can inspect state non invasive debuggine cannot perform execution controlling options like step , breakpoints etc. non invasive code flow is something like this

OpenProcess() , SuspendThread() , ReadProcessMemory() , ResumeThread() , CloseHandle()

Invasive debugging receives all the debugging events in the debuggee

CreateProcess (.,.,.,DEBUG_XXXXX,...,); so this can wait for all the DebugEvents
