The privilege level assigned to an application determines its access rights to certain data and capabilities to perform security-relevant operations. The number and specific use of privilege levels are architecture-specific, but most architectures support a minimum of two privilege levels (e.g. machine and user).
Security used to be about systems and software. As threats evolve, hardware engineers also have to familiarize themselves with trust and security terms and acronyms. If you are a hardware engineer interested in hardware trust and security, be sure to bookmark this page. If you spot a mistake or have ideas for enhancements, please get in touch.
