From the Paper
"Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time."
