The objective behind the concept of computer security actually varies quite a bit depending on the use of the computer. Computer security may include the protection of specific information from corruption or theft, for example. In general this can impose specific requirements on computers in addition to most standard system requirements. There are a number of different typical approaches that can be taken when it comes to improving computer security, including the following:

- Physically limiting the access to a computer so that computer security will not be compromised by those who are granted access to use it.

- Utilizing hardware mechanisms that can create and impose rules for specific computer programs, allowing computer security to be imposed without requiring individual programs to implement it.

- Implementing operating system or OS mechanisms that are capable of creating and imposing rules that avoid having to trust programs on the computer.

- Implementing programming strategies that allow subversion to be resisted and make computer programs more dependable.

In most cases, the computer security devices that are put into place are dependent upon the application uses the computer is created for. Different computer systems require different levels of security, as the level of privacy or protection needed is going to vary significantly. Computer systems under government control, for example, require a much higher level of security than computers used by students in a university setting. The level of required computer security, then, along with what forms of security are implemented, are going to vary significantly as well.

Implementing computer security may include creating or utilizing secure operating systems, though much of the science associated with this form of security was developed several decades ago. Security architecture is another option, and involves describing how specific security countermeasures and controls are positioned to protect the information technology. Firewalls are an example of security meant to protect computers from threats that travel via the internet or peer to peer connections. Chain of trust techniques are techniques that are used to ensure that all software on a computer is certified as authentic directly from the designers of the system. Access control is used to ensure the separation of privileges, ensuring that only specified people have the right capabilities on a computer system.

There are also cryptographic techniques which transform information into something that is meant to be indecipherable by anyone but approved persons. Information can also be secured for computer security purposes using backup files which allow important files to be protected by creating copies should they ever become corrupted or destroyed.

Essentially, the primary focus of the computer security field of information technology is to protect the integrity of computers, the data contained within them, and any information that may require restricted access. Some level of computer security is needed by anyone who owns a computer, including student computers in a university setting, computers owned and operated by the government, and even the laptop that you use to check your e-mail at night.
