Unformatted text preview: 1999, and to over 24 million by 2001 [6]. 1999, In the US, in 1993, Marc Andreesen, an In undergraduate student at the University of Illinois at Urbana-Champaigne, and his team, while working on a National Center for Supercomputing Applications (NCSA), developed another graphic user interface browser they named Mosaic. Mosaic The graphic user interface (GUI) popularized the user and fueled the growth of the world wide web to bring it to the point where it is today. web The Emergence of the Social and Ethical Problems in Computing The Emergence of Computer Crimes – The known history of computer crimes is not as old as computing is. The – One can perhaps say that the history of computer crimes started with the One invention of the computer virus. invention – The term virus is derived from a Latin word virus which means poison. For The virus virus generations, even before the birth of modern medicine, the term had remained mostly in medical circles, meaning a foreign agent injecting itself in a living body, feeding on it to grow and multiply. – As it reproduces itself in the new environment, it spreads throughout the As victim's body slowly disabling the body’s natural resistance to foreign objects, weakening the body’s ability to perform needed life functions and eventually causing serious, sometimes fatal effects to the body. – A computer virus, defined as a self-propagating computer program designed computer to alter or destroy a computer system resource, follows almost the same pattern but instead of using the living body, it uses software to attach itself, grow, reproduce and spread in the new environment. – As it spreads in the new environment, it attacks major system resources that As include the surrogate software itself, data, and sometimes hardware weakening the capacity of these resources to perform the needed functions and eventually bringing the system down. – – The word virus was first assigned a non-biological meaning in The the 1972 science fiction stories about the G.O.D. machine, that were compiled in a book When Harly was One by David Gerrod When ( Ballantine Books, First Edition, New York, NY, 1972). The term was first used to describe a piece of unwanted computer code. – Later association of the term with a real world computer program Later was done by Fred Cohen, then a graduate student at the University of Southern California. – Cohen first presented his ideas to a graduate seminar class in Cohen information security in 1983. His seminar advisor, Len Adleman, was the first to assign the term "virus" to Cohen's concept. – As part of these experiments, Cohen wrote five programs, As actually viruses, to run on a VAX 11/750 running Unix, not to alter or destroy any computer resources but for class demonstration. During the demonstration, each virus obtained full control of the system within an hour [8]. full – From that simple beginning, computer viruses, and hence From computer crimes have been...
