Information warfare (IW) (different from cyberwarfare that attacks computers, software, and command control systems) is a concept involving the battlespace use and management of information and communication technology (ICT) in pursuit of a competitive advantage over an opponent. Information warfare is the manipulation of information trusted by a target without the target's awareness so that the target will make decisions against their interest but in the interest of the one conducting information warfare. As a result, it is not clear when information warfare begins, ends, and how strong or destructive it is. Information warfare may involve the collection of tactical information, assurance(s) that one's information is valid, spreading of propaganda or disinformation to demoralize or manipulate the enemy and the public, undermining the quality of the opposing force's information, and denial of information-collection opportunities to opposing forces. Information warfare is closely linked to psychological warfare.
The United States Armed Forces' use of the term favors technology and hence tends to extend into the realms of electronic warfare, cyberwarfare, information assurance and computer network operations, attack, and defense. Other militaries use the much broader term Information Operations (IO) which, although making use of technology, focuses on the more human-related aspects of information use, including (amongst many others) social network analysis, decision analysis, and the human aspects of command and control.
Information warfare has been described as "the use of information to achieve our national objectives." According to NATO, "Information war is an operation conducted in order to gain an information advantage over the opponent."
Information warfare can take many forms:
Television, internet and radio transmission(s) can be jammed to disrupt communications, or hijacked for a disinformation campaign.
Logistics networks can be disabled.
Enemy communications networks can be disabled or spoofed, especially online social communities in modern days.
