Abstract
An endpoint has a tamper protection cache that identifies protected computing objects, along with a process cache that stores information for processes executing on the endpoint. By securing the tamper protection cache with reference to a trust authority external to the endpoint, or the operating system for the endpoint, computing objects listed in the tamper protection cache can be protected against unauthorized modifications from malware or other malicious or otherwise potentially unsafe code.
