While it is well known that letters can be intercepted and phone lines can be tapped, it is not so well known that even e-mails can be easily read. In fact it is commonly believed that the login password provides privacy and security.
This is not actually so!




Any employee of the Internet Service Provider (ISP) that you you use, can tap into your e-mail at your end or that of the recipient with the use of fairly basic equipment. Tapping can also be done by anyone who links up to the dozens of Internet routers through which your message passes.
The mail can even be accessed by someone at the phone company's office or a hacker who taps in through them.

There are also a number of more sophisticated methods and a wide range of equipment by which all electronic communication can be intercepted. These are used primarily by government agencies, but can also be employed by business rivals and competitors.

Such agencies can also use specially designed software that can automatically search all e-mails and faxes passing through a particular phone network for keywords, or analyze phone calls digitally. So even if you are using unlisted numbers, or public call offices and cyber cafés, your communication can be traced and intercepted by picking up commonly used terms or phrases.
