## FAQs
### Q: What is hardware security?
A: Hardware security is a discipline within computer security that focuses on protecting systems through hardware design and related controls. It covers topics such as access control, secure key storage, ensuring code authenticity, and securing the product supply chain.

### Q: Is hardware security part of computer security?
A: Yes. Hardware security is classified as a subclass of computer security and also as a subclass of security.

### Q: What areas does hardware security cover?
A: Hardware security involves hardware design and access control, and it includes secure multi-party computation and secure key storage. It also includes ensuring code authenticity and measures to ensure the supply chain that built the product is secure.

### Q: Why does the supply chain matter in hardware security?
A: Hardware security explicitly includes measures to ensure that the supply chain that built the product is secure. This treats the integrity of how hardware is produced and delivered as part of the security discipline.

## Why It Matters
Hardware security matters because it addresses security at the level of hardware design and the physical and production foundations of computing systems. As a part of computer security, it expands protection beyond software-only concerns by including access control mechanisms tied to hardware, secure key storage, and ensuring code authenticity. It also explicitly includes measures to ensure that the supply chain that built the product is secure, recognizing that security risks can arise during manufacturing, assembly, and delivery—not only during system operation. By covering secure multi-party computation alongside hardware design and key storage, hardware security spans both foundational system components and security-relevant computation. In practice, this discipline is relevant wherever trust in a computing product depends on the integrity of its hardware, the authenticity of the code it runs, and the security of the processes that produced it.

## Notable For
- Being explicitly defined as a discipline involving **hardware design** as a core security focus.
- Including **secure key storage** as a named area within its scope.
- Including **ensuring code authenticity** as a named area within its scope.
- Treating **supply chain security** (“the supply chain that built the product”) as part of the discipline.
- Being classified as both a **subclass of security** and a **subclass of computer security**.

## Body
### Classification and Position in Security
