Definition of Computer Security The NIST Computer Security Handbook [NIST95] defines the term computer security as follows: Computer Security: The protection afforded to an automated information system in order to attain the applicable objectives of preserving the integrity, availability,and confidentiality of information system resources (includes hardware, software, firmware, information/data, and telecommunications).   This definition introduces three key objectives that are at the heart of computer  security: Confidentiality: This term covers two related concepts:             Data confidentiality: Assures that private or confidential information is not made available or disclosed to unauthorized individuals.      Privacy: Assures that individuals control or influence what information related to them may be collected and stored and by whom and to whom that information may be disclosed.   Integrity: This term covers two related concepts:      Data integrity: Assures that information
