Security and privacy on the Internet
There are a lot of benefits from an open system like the Internet, but we are also exposed to hackers who break into computer systems just for fun, as well as to steal information or propagate
viruses. So how do you go about making online transactions secure? Security on the Web
The question of security is crucial when sending confidential information such as credit card numbers. For example, consider the process of buying a book on the Web. You have to type
your credit card number into an order form which passes from computer to computer on its way to the online bookstore. If one of the intermediary computers is illustrated by hackers, your data can
be copied. It is difficult to say how often this happens, but its technically possible.
To avoid risks, you should set all security alerts to high on your Web browser. Netscape Communicator and Internet Explorer display a lock when the Web page is secure and allow you to
disable or delete cookies. If you use online bank services, make sure your bank uses digital certificates. A popular
security standard is SET secure electronic transactions. E-mail privacy Similarly, as your e-mail message travels across the net, it is copied
temporarily on many computers in between. This means it can be read by unscrupulous people who illegally enter computer systems.
