Computer security is a branch of computer technology which can be known as information security too. This is applied to computers and networks. Computer security objective is the protection of information and corruption, property from theft or natural disaster while also allowing the information and property to remain productive to its actual intended users.

The collective processes and mechanisms by which the valuable information and services are protected from publication and which are protected from tampering and or collapse by the unauthorized activities by untrustworthy individuals. Computer security strategies often will differ from most other computer technologies because of its objective of preventing unwanted computer behaviour instead of enabling wanted computer behaviour.

Logic is what most technologies of computer security is based on. Security is not necessarily the primary goal of most computer applications. When a program is designed with security in mind this will often restrict the programís behaviour.

Computer security refers to technology to implement a secure operating system for the computer. Most of this kind of technology is based upon science which was developed in the 1980s and used to produce what may be some of the most impenetrable operating systems ever. The technology is in limited use today, although it is still valid. The main reason for this is because it imposes some changes to the system management and also because it is not widely understood. An example of such a computer security policy is the Bell-LaPadula model. An ultra-strong secure operating system are based on a technology called operating system kernel. This can guarantee that certain computer security policies are enforced in an operating system. The Bell-LaPadula model is based on a strategy on a coupling of special microprocessor hardware features. This would often involve the memory management unit, to a special correctly implemented operating system kernel. This will form a foundation for a secure computer security operating system which, if any critical part are implemented and designed correctly can ensure the absolute impossibility of any penetration by any hostile elements trying to break into the computer security. This is only enabled because the configuration not only imposes a security policy but it actually completely protects itself also from corruption from any other means. This is where ordinary operating systems lack the features of this kind of maximal level of computer security. This is where the design method needs to be precise, logical and deterministic.

Hardware based computer security or assisted computer security offers an alternative to software only computer security. Such devices like dongles may be considered more secure due to the physical access required in order to be compromised by using them.

Computer security is very much critical in almost any technology driven industry we are in now which operates on computer systems. Computer security can also be known and referred to as computer security. There are issues of computer based systems and addressing their countless vulnerabilities are an integral part of maintaining an operational industry.
