Cyber Threats: Executive Summary
It is important to note, from the onset, that even before the personal computer became as popular and as widely used as it is today, vandals still compromised computerized phone systems either for fun or for economic benefit. During the very early decades of IT, computer attacks were mostly committed by insiders, i.e. disgruntled employees of an entity (de Leeuw and Bergstra, 2007). The said attacks in this case were largely limited to physical damage to computing devices. At the time, "the systems were not networked with other systems…" (de Leeuw and Bergstra, 2007, p. 706). This was, however, until vandals discovered new ways of making use of computer systems to turn a profit or register protests. During these early days of technology, criminals would commonly modify data after subverting security systems via mostly authorized access. With the spread of telecommunications technology during the 1960s, computer criminals started learning how penetrate networks and systems. Vandals would often subvert phone systems with their intention being theft of services or just for amusement purposes.
The appearance of ARPANET, defined by de Leeuw and Bergstra (2007, p. 706) as "the world's first packet switching network," is seen by many as having set the stage for cyber attacks. In linking computers in numerous universities and other companies, ARPANET effectively "linked hackers all over the country…" leading to the emergence of more sophisticated cyber attacks (de Leeuw and Bergstra, 2007, p. 706). It was, however, not until the 1980s that vandals with varying levels of programming expertise begun to write malicious software designed to self-replicate and interfere with the normal functioning of personal computers.
The early 1990s, as Casey (2011) notes, saw the introduction of the World Wide Web and hence greater connectivity across the world. With the increased utilization of the internet, computer criminals developed ways of gaining unauthorized access to systems that were poorly protected. The motivation for this was in most cases financial or political. As the decade progressed, penetration as well as subversion of computing devices became a common avenue for the perpetration of crimes of a financial nature. With operating systems being strengthened further in the mid 90s so as to limit the occurrence of...
