Abstract
Systems, apparatuses and methods may provide for detecting an attempt by an operating system (OS) to access a non-OS managed resource and injecting, in response to the attempt, an access event into a platform security component via a guest kernel associated with the OS. Additionally, a response to the attempt may be made based on a policy response from the platform security component. In one example, the attempt is detected with respect to one or more extended page table (EPT) permissions set by a security virtual machine monitor (SVMM). Moreover, injecting the access event into the platform security component may include invoking a previously registered policy callback.
