This includes the malicious introduction of a virus, the malicious modification of email or the vandalism of Web pages. This is a now a popular activity amongst hackers and I consider it to be a real problem for anyone doing business on the Internet. As we shall see in the second article, businesses often fail to implement even the most basic password and access controls. This involves an employee using the computer system for his or her own purposes. Employees can write personal letters or run businesses from their employer's computers.
Employees can use email systems and the Internet for private purposes.
Of particular concern to business must be the explosive growth of and ready access to Internet pornography combined with the increasing tendency of employers to allow staff unrestricted Internet access. An equally serious risk is the increased possibility of virus infection from unauthorised files downloaded from the Internet. I hope that what I have already said will be sufficient to persuade even the most relaxed business owner that there are some areas of concern. I think that all businesses need to assess the adequacy of their protection against computer fraud, even those that do not currently do business on the Internet. For example, the insertion of a virus may take a matter of minutes but wipe out all the data that the business has collected from its inception.
