Computer Crime And Cyber Crime

ABSTRACT

The growing danger from crimes committed against computers, or against information oncomputers, is beginning to claim attention in national capitals. In most countries around theworld, however, existing laws are likely to be unenforceable against such crimes. National governments should examine their currentstatus to determine whether they are sufficient to combat the kinds of crimes discussed in thisreport. Where gaps exist, governments should draw on best practices from other countries andwork closely with industry to enact enforceable legal protections against these new crimes. The emergence of new types of crime as well as the commission of traditional crimes by meansof new technologies that we called “Cyber crime”. Moreover,

When computer viruses are used on a large scale, like with bank, government or hospital networks, these actions may be categorized as cyberterrorism. Computer hackers also engage inphishing scams, like asking for bank account numbers, and credit card theft. Computer crime refers to criminal activity involving a computer. The computer may be used in the commission of a crime or it may be the target. Net-crime refers to criminal use of the Internet. Cyber-crimes are essentially a combination of these two elements and can be best defined as "Offences that are committed against individuals or groups of individuals with a criminal motive to intentionally harm the reputation of the victim or cause physical or mental harm to the victim directly or indirectly using modern telecommunication networks such as the

It’s not a virus, although it usually behaves in a similar manner. It is stealthily inserted into the program where it lies dormant until specified conditions are met. Malicious software such as viruses and worms often contain logic bombs which are triggered at a specific payload or at a predefined time. The payload of a logic bomb is unknown to the user of the software, and the task that it executes unwanted. Program codes that are scheduled to execute at a particular time are known as “time-bombs”. For example, the infamous “Friday the 13th” virus which attacked the host systems only on specific dates; it “exploded” (duplicated itself) every Friday that happened to be the thirteenth of a month, thus causing system slowdowns.

4. Denial-of-Service attack

A Denial-of-Service (DoS) attack is an explicit attempt by attackers to deny service to intended users of that service. This causes the resource (e.g. a web server) to crash or slow down significantly so that no one can access it. Using this technique, the attacker can render a web site inoperable by sending massive amounts of traffic to the targeted site. A site may temporarily malfunction or crash completely, in any case resulting in inability of the system to communicate adequately. DoS attacks violate the acceptable use policies of virtually all
