In the last 30 years occurred a colossal growth in the communications area. At this moment here are data and information been transmited in network from anywhere in the earth (even from space) in a very efficient way. Tecnology of communication brought a immense opportunity for the criminal activity. Who are the criminals in the cyberspace? Organized groups, likethe mafiaand others. What is the focus of those criminals? Surely the financial activity. They found a new way of administrate their financial resources (among other things). People are involved with espionage activities through the use of communication systems. Usually they act for governments, armys, and through computers transmite the product of their thievery, that are commercial secrets, projects, formulas, etc.Even the data inside your personal computer are not safe and is a potential target for these thieves. If you control your finances by your PC, your personal information are at danger.Think about it. Why this happens? Can´t we be part of this communication system and still being completely safe? Why? Think about it. Despite all security and precautions in banks, houses, aeroplanes and business we still can´t trust completely in the comunications system. There are still robberies, kidnapped airplanes and business being defrauded. Almost nothing is really secure. If someone wants to focus its efforts and objectives on something, think about informational security, because is almost certain that someone will get from you what they want. We can´t wait for the cyberspace to become secure from the night to day, we should be on constant alert. Why? Because people can get into your house andworkplace, and they can cause irrecoverable damages, without even being there.
