Network Security

Understanding Network Security Threats - What is network security and how to learn network security technology is the main thing we are talking about today.
To understand, in part, why we are where we are today, you only have to remember that PC is the acronym for personal computer. The PC was born and, for many years, evolved as the tool of the individual. In fact, much of the early interest and growth came as a rebellion to what appeared as exclusionary attitudes and many restrictions of early data-processing departments. Admittedly, many PCs were tethered to company networks, but even then there was often considerable flexibility in software selection, settings preferences, and even sharing of resources such as folders and printers.
As a result, a huge industry of producers developed and sold devices, software, and services targeted at meeting user interests and needs, often with little or no thought about security. Prior to the Internet, a person could keep their computer resources safe simply by being careful about shared floppy disks.
Today, even the PCs of most individuals routinely connect to the largest network in the world (the Internet) to expand the user's reach and abilities. As the computing world grew, and skills and technology proliferated, people with less than honorable intentions discovered new and more powerful ways to apply their craft. Just as a gun makes a robber a greater threat, computers give the scam artist, terrorist, thief, or pervert the opportunity to reach out and hurt others in greater numbers and from longer distances.
