Technology, as defined in the New Lexicon Webster's Dictionary of English Language, is "the science of technical processes in a wide, though related field of knowledge". The technology of the 21st Century is the Internet or cyber space. The Internet was invented in the late 1960s. Back then, the Department of Defence called it ARPAnet (Advanced Research Projects Agency network) and it was intended to link research facilities, defence contractors, and government agencies. Today there are millions of computers o

There are further more tools used by hackers/crackers/phreakers against which we have to maintain our safeguards. Having a firewall system on our machine is vaccine enough against applications like Trojan Horses, Password Sniffers, Worms and Backdoors/ Trap Door. A Trojan horse is a program, which hides itself in another apparently benign program. When the victim runs the apparently benign program he or she also ends up running the hidden Trojan program. A worm is an autonomous agent capable of propagating itself without the use of another program or any action by a person. Worm attacks are rare, but it is still a method used by hackers when a new bug is found on an OS. This has the "advantage" of being able to hack a lot of sites in little time. A trap door is an entry point into a computer system that bypasses the normal security measures, hidden software or hardware mechanism that permits system protection mechanisms to be circumvented.

n the Internet. With this increase in number the challenges for the security industry are growing. Business institutions have both the technical concerns, such as the security of a credit card number and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users pose a new type of challenge. Also ensuring public authentication, and maintaining user detail privacy is one of the biggest concerns for security insurers the world over.

To understand the Internet requires one to view it not as a one-way street, but as a two-way road. It is a two way street because you get what you want and they get what they want - information. It is disturbing to know that one can be tracked all over the World Wide Web just from their mouse clicks thus eliminating user privacy. Our browser alone simply gives us away from the computer we are coming from, the software and hardware we are using, the details of the link we clicked on to possibly even our email address.
