Computer security hardware includes locks, cables, authenticators, dongles, and software that protect physical components or data. Locks and cables prevent theft, while dongles and authenticators prevent unauthorized access to programs. Internal components can also be used as security hardware with specific software.
There are many different types of computer security hardware, although they are typically designed to protect the physical components of a computer or the data on that computer. Some of the more common forms of security hardware are locks and cables used to secure computer components to a desk or cart to prevent theft. There are also security devices such as authenticators and dongles that can be used with a computer to help prevent unauthorized access to certain programs or data. The internal components of a computer can also be used as security hardware by some programs which can be used to make data available only on a particular system.
Computer security hardware refers to physical devices and products used to enhance or enhance computer security. There are cables and padlocks, for example, to physically secure a computer and its components within a given environment. Metal cables can be used to keep a laptop connected to a desk or cart, preventing others from stealing the laptop. There are also padlocks that can be used as security hardware, often to secure wire cables or prevent access to a computer’s internal components without a key.
Some computer security hardware is more specialized in nature and is designed to prevent access to a computer system or a program on that computer. Security dongles, for example, are devices that can be easily plugged into a computer, often through a universal serial bus (USB) port, to allow access to that computer. Someone who doesn’t have the dongle is unable to access the data on that system. There are also authenticators that can be used as computer security hardware, which are typically tied to a particular program and prevent unauthorized access to those programs.
It is also possible for the physical components inside a computer case or tower to be used as security hardware. This typically requires particular software, however, which can essentially be used to link software or data on a computer to information derived from components in that computer. When someone wants to access data protected in this way, the software checks for such components and provides the data only if such components are found. This type of computer security hardware prevents someone from copying data or programs from one computer system and accessing them on another system.
