Hardware refers to the physical components of a computer system or electronic device, such as processors, memory chips, hard drives, network cards, and peripherals. In cybersecurity, hardware plays a critical role in protecting digital assets by providing a foundation for secure operations. Specialized hardware, like firewalls, hardware security modules (HSMs), and trusted platform modules (TPMs), can be used to enforce security policies, isolate sensitive processes, and protect cryptographic keys. Hardware-based isolation is a security technique that uses dedicated physical devices to separate and protect networks or systems from external threats, reducing the risk of unauthorized access and malware attacks. Unlike software solutions, hardware-based security is less vulnerable to tampering, making it essential for high-assurance environments.
