The Internet is a great way to communicate and a tremendous source of information. Newspapers, magazines, and television programs flood us with the Web addresses of companies offering products and services.
Retailers post catalogs and accept orders online.
Stockbrokers, insurance companies, and banks offer account information online and many of their customers conduct their business on their Web sites. As interest in this technology continues to grow, so do questions about security. Computer security is a serious concern, especially when sensitive information such as personal financial data is involved. Left unprotected, data traveling over the Internet can be read by an outside third party. However, there are technologies available that can protect sensitive data even on the public Internet.
