استفسار بخصوص kernel mode

[mr.gedo]

السلام عليكم ورحمة الله وبركاته
 كنت حابب أسأل هل البرمجة أو التعامل مع الـ Kernel Mode آمن ولا فيه مخاطر؟
وهل حد هنا اشتغل أو جرب يبرمج على مستوى الـ Kernel قبل كده، زي كتابة Drivers مثلاً؟
ولو في، إيه أكتر مشاكل قابلتكم مقارنة بالـ User Mode؟

Kernel mode programming absolutely involves risk.  You can bluesreen the machine, or get
computer into a state where you must boot in safe mode to remove the driver before the 
OS will load again.

Kernel mode differs from user mode; the tools and design approach are different, but studying the kernel is essential these days.

Many anti-cheat programs for games and hardware emulators require access to the kernel.

However, ring 0 debuggers (like Windbg) are more austere than ring 3 debuggers (x64Dbg, etc.).
Regarding risks, there aren't really any; all kernel driver developers work with virtual machines.
