ICT have become targets of malevolence (theft of computers or data, hijacking of resources ...) or means to commit unlawful acts (blackmail, embezzlement, money laundering money ...). The Internet facilitates traditional crimes, especially those associated with economic crime, and gives rise to new forms of crime (computer fraud, software piracy ...).
Dematerialisation services and transactions, tools for linking and communication, the ability to act at a distance and under false names or identities usurped to go through many intermediate technology (servers, access providers, etc..) and from different countries: this allows all forms of organization, trade and criminal activity very profitable under the investment required and the risk involved.
Furthermore, in cyberspace, anyone can contact anyone, anytime, anywhere. Users - children, elderly or other people without stories - rub shoulders with virtually all kinds of malicious actors (pedophiles, terrorists, criminals, delinquents, professional criminals, etc..). Internet is therefore an area where risk of arson data is structural, pervasive and permanent.
Beyond their interest for people, infrastructures and telecommunications are also important strategic resources for organizations or States. They are the target of cyber threats on their availability, integrity or confidentiality. They can also be used to manipulate opinion (indoctrination, spreading rumors ...), for espionage, surveillance and social control, or to destabilize an economy or a state. The Internet is certainly a wonderful communication tool, but it is also an instrument of power and a weapon of war.
The democratization of access to computers and more precisely to the Internet and the globalization of networks are associated with the development of cybercrime. It is a broad term that includes "all criminal offenses likely to commit on or through a computer system usually connected to a network. "
This is a new form of crime and delinquency that differs from traditional forms in that it is in a virtual space called cyberspace. In recent years the democratization of access to information technology and globalization networks were key factors for the development of cybercrime.
