KASPERSKY 2013 BLUE SCREEN WINDOWS 7 PATCH

Reliability issues resulting from multiple programs attempting to patch the same parts of the kernel.

Kernel Patch Protection protects against these negative effects, which include: Patching the kernel has never been supported by Microsoft because it can cause a number of negative effects. Since its creation in 2005, Microsoft has so far released two major updates to KPP, each designed to break known bypass techniques in previous versions. Periodic updates to KPP also make it a "moving target", as bypass techniques that may work for a while are likely to break with the next update.

With highly obfuscated code and misleading symbol names, KPP employs security through obscurity to hinder attempts to bypass it. KPP does however present a significant obstacle to successful kernel patching.

Ultimately, since device drivers have the same privilege level as the kernel itself, it is impossible to completely prevent drivers from bypassing Kernel Patch Protection and then patching the kernel.

KASPERSKY 2013 BLUE SCREEN WINDOWS 7 DRIVER

It does not offer any protection against one device driver patching another. Kernel Patch Protection only defends against device drivers modifying the kernel.

Modifying or patching code contained within the kernel itself, or the HAL or NDIS kernel libraries.

Using kernel stacks not allocated by the kernel.

Modifying the interrupt descriptor table.

Modifying system service descriptor tables.

The corresponding bugcheck number is 0x109, the bugcheck code is CRITICAL_STRUCTURE_CORRUPTION. If a modification is detected, then Windows will initiate a bug check and shut down the system, with a blue screen and/or reboot. It works by periodically checking to make sure that protected system structures in the kernel have not been modified. Kernel Patch Protection is the technology that enforces these restrictions. In 圆4 editions of Windows, Microsoft began to enforce restrictions on what structures drivers can and cannot modify. As a result, some x86 software, notably certain security and antivirus programs, were designed to perform needed tasks through loading drivers that modify core kernel structures. However in x86 editions of Windows, Windows does not enforce this expectation. Device drivers are expected to not modify or patch core system structures within the kernel.

The Windows kernel is designed so that device drivers have the same privilege level as the kernel itself.

KASPERSKY 2013 BLUE SCREEN WINDOWS 7 SOFTWARE

Nevertheless, Kernel Patch Protection can still prevent problems of system stability, reliability, and performance caused by legitimate software patching the kernel in unsupported ways. This has led to criticism that since KPP is an imperfect defense, the problems caused to antivirus vendors outweigh the benefits because authors of malicious software will simply find ways around its defenses. However, because of the design of the Windows kernel, Kernel Patch Protection cannot completely prevent kernel patching. Because of this, Kernel Patch Protection resulted in antivirus makers having to redesign their software without using kernel patching techniques. These techniques will not work on computers running 圆4 editions of Windows. Since patching the kernel is possible in 32-bit (x86) editions of Windows, several antivirus software developers use kernel patching to implement antivirus and other security services. Although Microsoft does not recommend it, it is possible to patch the kernel on x86 editions of Windows however, with the 圆4 editions of Windows, Microsoft chose to implement additional protection and technical barriers to kernel patching. Such modification has never been supported by Microsoft because, according to Microsoft, it can greatly reduce system security, reliability, and performance. "Patching the kernel" refers to unsupported modification of the central component or kernel of the Windows operating system.

It was first introduced in 2005 with the 圆4 editions of Windows XP and Windows Server 2003 Service Pack 1. Kernel Patch Protection ( KPP), informally known as PatchGuard, is a feature of 64-bit ( 圆4) editions of Microsoft Windows that prevents patching the kernel. The kernel connects the application software to the hardware of a computer.
