Information Security

The incredible growth of the Internet has excited businesses and consumers with its promise of changing the way we live and work. But a major concern has been just how secure the Internet is especially when you are sending sensitive information through it.

Information security is provided on computers and over the Internet by a variety of methods. A simple but straightforward security method is to only keep sensitive information on storage media. But the most popular forms of security all rely on encryption in such a way that only the person (or computer) with the key can decode it.

Computer encryption is based on the science of cryptography. Before the digital age, the biggest users of cryptography were governments, particularly for military purposes. But most recent forms of cryptography rely on computers, simply because a human-based code is too easy for a computer to crack.

Another process is authentication used to verify that the information comes from a trusted source. Basically, if information is “authentic”, you know who created it and you know that it has not been altered in any way since that person created it. These two processes, encryption and authentication, work hand-in-hand to create a secure environment.

There are several ways to authenticate a person or information on a computer: passwords, pass cards and digital signatures.
