Data security

Abstract

The need for computer security has grown every year since the creation of computer systems, but yet with such a high demand, there are many systems that are, by no means, adecuetly protected.This paper will discuss the three classes of vulnerabilities of security. The three classes are: those that threaten the physical integrity of the computer installation and its data, those that threaten the loss or compromise of the data from outside the computersite, and those that threaten loss or compromise of data from inside the computer site.The chief physical risk to a computer site is fire, acts of sabotage, industrial accidents, natural disasters, and mechanical or electrial malfunction of the computer system. Outside threats are those people who do not work for a particular firm, but yet wish to gain information about it that is not readily accessible to them. Inside threats come from employees who wish to compromise the computer system weither for gain, accident, or past time. Each one of these topics will be dealt withThe next part of the paper deals with the subject of setting up a security program. The first step in this subject is the study to access the probability of an event occuring, and determining it as either fatal to the business, very serious, moderately serious, relatively unimportant, or seriousness unknown. Some of the security techniques of checks and tests on the system are then discused.
