Fight against computer hackers
Ø 1) Read the headings of the texts 7.24; 7.30 and 7.31, and make a supposition what topic they are devoted to. Ø 2) Name “the signal words” which help the author to back up the idea of computer security with examples. Ø 3) Read the text and say whether the questions of losses to the business due to computer breaking are covered in it.
Most companies think hackers would never break into their computer systems and fail to take even the most basic security precautions. Firms wishing to does business on the Internet will have to ensure transactions are absolutely secure in order to win over consumer confidence. According to one recent survey, authored by Mr. Simple, two thirds of top Irish companies do not have a contingency plan for a breach in computer security. More than half have detected or been infected by a computer virus. The most important thing managers can do is improve their understanding of what the risks are. Often, a high-tech firewall may be less effective than a thorough review of who has, and should not have, access to the company computer system. When hackers break into a system, they always try to find the default log-on name and password, and then invent several innocuous-looking log-ons for them to ensure permanent access to the system. Managers should erase the default log-on once the system is up and running. While many companies have a general fear of a break-in by hackers - and are unclear how to prevent such an attack - they are in fact more likely to suffer at the hands of unwitting or malevolent insiders. Analysts in the United States, where the rate of computerisation is far higher than in Europe, say computer security can only become more essential to business as an increasing number of transactions take place over the Internet. Already, the FBI estimates an annual loss of $7.5 billion as a result of electronic attack. One survey revealed that the US Department of Defense discovered 88 per cent of their computers are penetrable. In 96 per cent of the cases where hackers got in, their intrusions went undetected, according to the report. In one celebrated case, a Russian computer hacker successfully breached a large number of a major bank’s corporate accounts, stole $400, 000, and illegally transferred another $11.6 million. In 1994, the US Secret Service uncovered a $50 billion telephone card scam in which many accounts of AT& T, MCI and Sprint cardholders were regularly abused. Companies should undertake some measures to secure for customers sending their credit card information down the phone line. The system would use high-speed telephone lines and firewalls to protect the information in the base, while customers will use a special computer programme to send financial information. The programme encrypts credit card numbers and sends them in separate batches. There have been cases of people breaking through the SSL 40-bit encryption. But there are easier ways to get credit card numbers. In some companies there are hacker-turned-corporate advisors whose responsibility is computer security, telling business executives how to avoid being a victim.
