Computer Fraud and Crimes

In the world of computers, computer fraud and computer crime are very prevalent issues facing every computer user. This ranges from system administrators to personal computer users who do work in the office or at home. Computers without any means of security are vulnerable to attacks from viruses, worms, and illegal computer hackers. If the proper steps are not taken, safe computing may become a thing of the past. Many security measures are being implemented to protect against illegalities.

Companies are becoming more aware and threatened by the fact that their computers are prone to attack. Virus scanners are becoming necessities on all machines. Installing and monitoring these virus scanners takes many man hours and a lot of money for site licenses. Many server programs are coming equipped with a program called "netlog." This is a program that monitors the computer use of the employees in a company on the network. The program monitors memory and file usage. A qualified system administrator should be able to tell by the amounts of memory being used and the file usage if something is going on that should not be. If a virus is found, system administrators can pinpoint the user who put the virus into the network and investigate whether or not there was any malice intended.

One computer application that is becoming more widely used and, therefore, more widely abused, is the use of electronic mail or email. In the present day, illegal hackers can read email going through a server fairly easily. Email consists of not only personal transactions, but business and financial transactions. There are not many encryption procedures out for email yet. As
Gates describes, soon email encryption will become a regular addition to email just as a hard disk drive has become a regular addition to a computer (Gates
p.97-98).

Encrypting email can be done with two prime numbers used as keys. The public key will be listed on the Internet or in an email message. The second key will be private, which only the user will have. The sender will encrypt the message with the public key, send it to the recipient, who will then decipher it again with his or her private key. This method is not foolproof, but it is not easy to unlock either. The numbers being used will probably be over 60 digits in length
(Gates p.98-99).

The Internet also poses more problems to users. This problem faces the home user more than the business user. When a person logs onto the Internet, he or she may download a file corrupted with a virus.

  • The Statute of Frauds and the Uniform Commercial Code

    820 Words  | 2 Pages

    The primary purpose of the “Statute of Frauds” (SOF) is to protect the interests of parties once they are involved in litigating a contract dispute (Spagnola, 2008). The relevant statutes are reliant upon state jurisdictions to determine whether the contract falls under the SOF, and whether the writing of the contract satisfies the requirements of the statute of frauds (Spagnola, 2008). However, all contracts are not covered under the SOF. In essence, for a contract to be deemed as legal by definition of the SOF, there must be verification of the following requirements for formation of the contract, which are as follows: (1) There must be least two parties to the contract, (2) There must be a mutual agreement and acceptance on the price to pay for goods and services offered, (3) The subject matter or reason for entering the contract, must be clearly understood by all parties to the contract, (4) and there must be a stipulated time for performance of duties under the contractual obligations (Spagnola, 2008). Lastly, there are five categories of contracts that are covered under the SOF, which are as follows: (1) The transfer of real property interests, (2) Contracts that are not performable within one year, (3) Contracts in consideration of marriage, (4) Surtees and guarantees (answering to the debt of another), and (5) Uniform Commercial Code (U.C.C.) provisions regarding the sale of goods or services, legally valued over five hundred dollars ($500.00) (Spagnola, 2008).

    The Computer Fraud and Abuse Act (CFAA) of 1986 is a foundational piece of legislation that has shaped computer crime laws for the United States.

    In America, simply having a job is not enough. Nowadays, jobs are hard to find and most only offer part-time employment. It is near impossible to afford the cost of living while earning entry-level wages. The job market has become hostile, and it has gotten to the point that one must have formal training or a marketable education in order to obtain a stable position that offers decent wages. With this realization, many people have decided to go to college. Those that are in the market for a college education face many choices. The most common: community colleges, which do not make a profit, and technical schools or online schools, which are in the business to make a profit. These schools are called for-profit schools. Many people do not realize how important it is to shop around when debating which school to attend. Nowadays, one must get an education about their education.
