Hardware security is known as a vulnerability protection which in form of physical device instead of an installed software on hardware of a computer system. From a cybersecurity perspective, hardware security has been considered as the most trusted security solution for digital system. Computer manufacturers have been trying to enable hardware security chip set on their products, and it is still on the early stage.
Hardware security provides several benefits; however, hardware carries similar risks as software due to advanced threats which can result in losing value information such as:
- Hardware failure – is the result of defective parts or physical damages, and your devices may stop working at any time without notice.
- Theft – can be lost easily due to careless use or stolen (USB, hard drive).
- Hardware Trojan – is a chip that is not part of the original board designs which causes an integrated circuit (IC) change functional behaviour.
- Incompatibility – rely on computer system which may or may not support after a period of time, and it is more difficult to upgrade the hardware than purchase a newer device.
- Meltdown/Spectre – are both very recent threat that exploit critical vulnerabilities in modern processors and allow program to steal data on computer.
Hardware attack requires to have extensive knowledge of the hardware and tools; moreover, it is harder than software attack. Adversary is more delicate and sensitive information is priceless for some reason. Therefore, it is necessary to design and develop more secure computer hardware.
