Information warfare (IW) 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 own 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.Group specific: Information warfare (IW) is a concept involving the battlespace use and management of information and communication technology (ICT) in pursuit of a competitive advantage over an opponent.

The United States military focus tends to favor technology, and hence tends to extend into the realms of electronic warfare, cyberwarfare, information assurance and computer network operations, attack and defense. Most of the rest of the world use the much broader term of 'Information Operations' 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.
