The terms information security, computer security and information assurance are frequently incorrectly used interchangeably. These fields are interrelated often and share the common goals of protecting the confidentiality, integrity and availability of information; however, there are some subtle differences between them.

Computer security can focus on ensuring the availability and correct operation of a computer system without concern for the information stored or processed by the computer.
