A data processing system (DPS) uses platform protection technology (PPT) to protect some or all of the code and data belonging to certain software modules. The PPT may include a virtual machine monitor (VMM) to enable an untrusted application and a trusted application to run on top of a single operating system (OS), while preventing the untrusted application from accessing memory used by the trusted application. The VMM may use a first extended page table (EPT) to translate a guest physical address (GPA) into a first host physical address (HPA) for the untrusted application. The VMM may use a second EPT to translate the GPA into a second HPA for the trusted application. The first and second EPTs may map the same GPA to different HPAs. Other embodiments are described and claimed.
