Abstract: | A strong factor in the early development of computers was security – the computations that motivated their development, such
as decrypting intercepted messages, generating gunnery tables, and developing weapons, had military applications. But the
computers themselves were so big and so few that they were relatively easy to protect simply by limiting physical access to
them to their programmers and operators. Today, computers have shrunk so that a web server can be hidden in a matchbox and
have become so common that few people can give an accurate count of the number they have in their homes and automobiles, much
less the number they use in the course of a day. Computers constantly communicate with one another; an isolated computer is
crippled. The meaning and implications of “computer security” have changed over the years as well. This paper reviews major
concepts and principles of computer security as it stands today. It strives not to delve deeply into specific technical areas
such as operating system security, access control, network security, intrusion detection, and so on, but to paint the topic
with a broad brush.
