Microsoft this week announced Kernel Data Protection, new technology that aims to protect the Windows kernel and drivers from data corruption attacks.

KDP builds upon the technology included by default in Secured-core PCs and adds another layer of protection for configuration data.

In Windows 10, KDP is implemented in two parts, namely static KDP, where software running in kernel mode can protect a section of its own image, and dynamic KDP, where kernel-mode software can "Allocate and release read-only memory from a 'secure pool'," Microsoft says.

Already included in the latest Windows 10 Insider Build, the KDP does not work with executable pages, since protection to those is provided by hypervisor-protected code integrity.

"These are just a few examples of how useful protecting kernel and driver memory as read-only can be for the security and integrity of the system. As KDP is adopted more broadly, we expect to be able to expand the scope of protection as we look to protect against data corruption attacks more broadly," Microsoft notes.
