Problem Statement
What is the purpose of kernel patch protection (KPP) as implemented in some operating systems?
Explanation
Kernel Patch Protection (such as PatchGuard in 64-bit Windows) periodically checks critical system structures to detect unauthorized modifications of the kernel. If tampering is detected, the OS may trigger a bug check or shut down to protect integrity. This defense elevates OS security by blocking rootkits and kernel-level malware.
