Introduction In the past decade, computer and networking technology has seen enormous growth. This growth however, has not come without a price. With the advent of the "Information Highway", as it\'s coined, a new methodology in crime has been created. Electronic crime has been responsible for some of the most financially devastating victimizations in society.
In the recent past, society has seen malicious editing of the Justice Department web page (1), unauthorized access into classified government computer files, phone card and credit card fraud, and electronic embezzlement. All these crimes are committed in the name of "free speech." These new breed of criminals claim that information should not be suppressed or protected and that the crimes they commit are really not crimes at all. What they choose to deny is that the nature of their actions are slowly consuming the fabric of our country\'s moral and ethical trust in the information age.
Federal law enforcement agencies, as well as commercial computer companies, have been scrambling around in an attempt to "educate" the public on how to prevent computer crime from happening to them. They inform us whenever there is an attack, provide us with mostly ineffective anti-virus software, and we are left feeling isolated and vulnerable. I do not feel that this defensive posture is effective because it is not pro-active. Society is still being attacked by highly skilled computer criminals of which we know very little about them, their motives, and their tools of the trade. Therefore, to be effective in defense, we must understand how these attacks take place from a technical stand-point. To some degree, we must learn to become a computer criminal. Then we will be in a better position to defend against these victimizations that affect us on both the financial and emotional level. In this paper, we will explore these areas of which we know so little, and will also see that computers are really extensions of people. An attack on a computer\'s vulnerabilities are really an attack on peoples\' vulnerabilities.
Today, computer systems are under attack from a multitude of sources. These range from malicious code, such as viruses and worms, to human threats, such as hackers and phone "phreaks." These attacks target different characteristics of a system. This leads to the possibility that a particular system is more susceptible to certain kinds of attacks.
Malicious code, such as viruses and worms, attack a system in one of two ways, either internally or externally. Traditionally, the virus has been an internal threat (an attack from within the company), while the worm, to a large extent, has been a threat from an external source (a person attacking from the outside via modem or connecting network).
Human threats are perpetrated by individuals or groups of individuals that attempt to penetrate systems through computer networks, public switched telephone networks or other sources. These attacks generally target known security vulnerabilities of systems. Many of these vulnerabilities are simply due to configuration errors.
Malicious Code Viruses and worms are related classes of malicious code; as a result they are often confused. Both share the primary objective of replication. However, they are distinctly different with respect to the techniques they use and their host system requirements. This distinction is due to the disjoint sets of host systems they attack. Viruses have been almost exclusively restricted to personal computers, while worms have attacked only multi-user systems.
A careful examination of the histories of viruses and worms can highlight the differences and similarities between these classes of malicious code. The characteristics shown by these histories can be used to explain the differences between the environments in which they are found. Viruses and worms have very different functional requirements; currently no class of systems simultaneously meets the needs of both.
A review of the development of personal computers and multi-tasking workstations will show that the gap in functionality between these classes of systems is narrowing rapidly. In the future, a single system may meet all of the requirements necessary to support both worms and viruses. This implies that worms and viruses may begin to appear in new classes of systems. A knowledge of the histories of viruses and worms may make it possible to predict how malicious code will cause problems in the future.
Computer CrimeComputer Crime Computer crimes need to be prevented and halted thought increased computer network security measures as well as tougher laws and enforcement of those laws in cyberspace: Computer crime is generally defined as any crime accomplished through special knowledge of computer technology. All that is required is a personal computer, a modem, and a phone line. Increasing instances of white-collar crime involve computers as more businesses automate and information becomes an important asset
Computer Crime In The 1990'sComputer Crime In The 1990\'s We\'re being ushered into the digital frontier. It\'s a cyberland with incredible promise and untold dangers. Are we prepared ? It\'s a battle between modern day computer cops and digital hackers. Essentially just think what is controlled by computer systems, virtually everything. By programming a telephone voice mail to repeat the word yes over and over again a hacker has beaten the system. The hacker of the 1990\'s is increasingly becoming more organized very clea
Hacking to PeacesHacking to Peaces The Information Superhighway possesses common traits with a regular highway. People travel on it daily and attempt to get to a predetermined destination. There are evil criminals who want to violate citizens in any way possible. A reckless driver who runs another off the road is like a good hacker. Hacking is the way to torment people on the Internet. Most of the mainstream hacking community feel that it is their right to confuse others for their entertainment. Simply stated,

Computer CrimeComputer Crime Computer crime is a very broad term. It could mean anything from a total invasion by a hacker into the federal government or just the simple fact of one person letting another borrow a copy of his favorite flying game. Computers are defined in the dictionary as a machine that computes (WBD vol. 23). But to most people it is a machine that\'s helps us do a task easier. As we move into the 21th century though one thing is for sure, the computer will help crime become more prevalent.
