Computer security is a term that we hear increasingly nowadays. With the arrival of home PCs, computers have become household electronic gadgets that are used for a variety of purposes such as word processing, music, e-mail, and gaming etc. Since the PCs also hold significant amounts of personal data (credit card numbers and bank account details etc.) they have become enticing targets for the hackers. This is a primary reason behind an explosive growth in the computer security discipline within the larger context of the Information Technology (IT) domain. An accelerated growth in the Information and Communication Technologies (ICT) has brought the computer security issues into the limelight. The term ‘computer security’ may be defined as:
An effort to create a secure computing platform, designed in such a way that the agents (users or programs) can only perform some limited/allowed actions. This involves specifying and implementing a stringent security policy that includes protection of information assets through the use of technology, processes, and training. It also includes the various measures and controls to ensure the security and availability of the information that is processed, stored, and transmitted by a computer system over a network.
