What is Cyberwarfare?

Cyberspace has become another important dimension of warfare, where nations can carry out conflicts without the clashes of traditional troops and machines. This allows countries with minimal military presence to be as strong as other nations in cyberspace. Cyberwarfare is an Internet-based conflict that involves the penetration of computer systems and networks of other nations. These attackers have the resources and expertise to launch massive Internet-based attacks against other nations to cause damage or disrupt services, such as shutting down a power grid.
An example of a state-sponsored attack involved the Stuxnet malware that was designed to damage Iran’s nuclear enrichment plant. Stuxnet malware did not hijack targeted computers to steal information. It was designed to damage physical equipment that was controlled by computers. It used modular coding that was programmed to perform a specific task within the malware. It used stolen digital certificates so the attack appeared legitimate to the system.
