ABSTRACT:
A secure process may be created which does not allow code to be injected into it, does not allow modification of its memory or inspection of its memory. The resources protected in a secure process include all the internal state and threads running in the secure process. Once a secure process is created, the secure process is protected from access by non-secure processes. Process creation occurs atomically in kernel mode. Creating the infrastructure of a process in kernel mode enables security features to be applied that are difficult or impossible to apply in user mode. By moving setup actions previously occurring in user mode such as creating the initial thread, allocating the stack, initialization of the parameter block, environment block and context record into kernel mode, the need of the caller for full access fights to the created process is removed.
