Definition - What does Netwar mean?
The war is waged through decentralized and flexible network structures. It essentially refers to the conflict being waged over the Internet and networked systems such as information mobilization, hackings and counter-hackings, and, to a lesser extent, even very simple heated arguments over random topics between groups or cells.
Techopedia explains Netwar
Networked actors are a collection of people and groups without a clear hierarchy of command and who communicate through "all points" of communication channels with considerable aggregate bandwidth and have a global reach through the Internet. In contrast, highly institutionalized organizations such as the police and the armed forces communicate in highly hierarchical and centralized channels. As a point of comparison, cyberwar often revolves around a militaristic use of networked interfaces such as espionage and sabotage, whereas netwar is characterized more by massive information drives designed to enlighten the general public of specific information usually held secret by larger institutions.
