What is hardware security?

Hardware security refers to the protection of physical devices and components, such as computers, servers, and embedded systems, from attacks and unauthorized access. This field involves securing hardware against threats like tampering, cloning, side-channel attacks, and hardware Trojans. Hardware security specialists use techniques such as secure hardware design, cryptographic modules, and physical security measures to ensure device integrity and data protection. It is essential for industries where sensitive information is stored or processed, including finance, healthcare, and defense.
