Computer security compromised by hardware failure

Computer security compromised by hardware failure is a branch of computer security applied to hardware.The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. Such secret information could be retrieved by different ways. This article focus on the retrieval of data thanks to misused hardware or hardware failure.
