Cyber warfare, a new aspect of modern warfare
Cyber warfare nowadays is a new and very important concept of the modern world. After land, sea, air and space, the war has entered the fifth dimension: cyberspace. Some computer glitches or attacks paralyze military e-mail systems, refineries and pipelines explode, air traffic control systems collapse, trains derail, financial data gets misdirected, power grids damaged, satellites go out of control. Worst of all, the identity of the aggressor remains a mystery. The effects of a cyber war are similar to those of a nuclear attack. This requires protective measures and security for the information that circulates in these communication systems and networks and constitutes one of the challenges of today’s time. Threats to communication and information systems have made cyber defense in the field of homeland security an element that must be taken into consideration.
