section Summary
 
 
In this age of universal electronic connectivity of viruses and hackers, of electronic Eavesdropping and electronic fraud, there is indeed no time at which security does not matter. The explosive growth in computer systems and their interconnections via network has increased the dependence of both organizations and individuals on the information stored and communicated using these systems. This, in turn, has led to a heightened awareness of the need to protect the data and messages, and to protect systems from network based attacks. As we tend towards a more and more computer centric world, the concept of data security has attained a paramount importance. Though present day security systems offer a good level of protection, they are incapable of providing a "trust worthy" environment and are vulnerable to unexpected attacks. The generic name for the collection of tools design to protect data and to thwart hackers is computer security.
