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.

Unavoidable actions employ security measures that cannot be prevented or neutralized. This strategy is based on the assumption that the system has been penetrated, but an intruder cannot prevent the defensive mechanism from being employed. Examples of this strategy include rebooting, using physical unclonable functions, and using a security switch.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
In computer security, a threat is a potential negative action or event enabled by a vulnerability that results in an unwanted impact to a computer system or application.. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility ...
The following outline is provided as an overview of and topical guide to computer security: . Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the ...
Although attention to security can reduce the risk of attack, achieving perfect security for a complex system is impossible, and many security measures have unacceptable cost or usability downsides. [30] For example, reducing the complexity and functionality of the system is effective at reducing the attack surface. [31]
A cyberattack is any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system.
Some security experts feel that including the "Discoverability" element as the last D rewards security through obscurity, so some organizations have either moved to a DREAD-D "DREAD minus D" scale (which omits Discoverability) or always assume that Discoverability is at its maximum rating.
