Information warfare is a broad, contested term for using information and information-related capabilities to influence, disrupt or protect decision-making. It has no single definition established by the official sources discussed here. For practical detection, organizations should look beyond whether a claim is true or false: assess who may be acting, how activity is coordinated, what content is being spread, its scale and reach, and its likely effects. Treat indicators as leads to verify—not proof of hostile intent or attribution.
What does “information warfare” mean?
The phrase is used differently in military doctrine, government policy, academic work and journalism. NATO’s 2024 policy uses the more specific term information threats for intentional, harmful, manipulative and coordinated activity by state or non-state actors in the information environment that has, or could have, a negative impact. NATO’s category includes information operations, foreign information manipulation and interference, and disinformation. It is an institutional policy definition, not a universal definition of information warfare.
Military doctrine uses information operations in a narrower context. The NIST CSRC glossary records the CNSSI 4009-2022 definition, sourced to U.S. Department of Defense Joint Publication 3-13: “The integrated employment, during military operations, of information-related capabilities in concert with other lines of operation to influence, disrupt, corrupt, or usurp the decision-making of adversaries and potential adversaries while protecting our own.” That definition describes military operations; it should not automatically be substituted for every use of information warfare.
NATO doctrine also has a defined operational context. The UK Ministry of Defence describes Allied Joint Publication 10.1 as NATO doctrine for the operational level, applicable in peace, crisis and conflict, and intended to coordinate information activities and support understanding of the information environment. The UK page identifies Edition A, Version 1, with UK national elements, and was last updated on 31 July 2023.

How is information warfare different from misinformation?
In NATO’s terminology, misinformation is false or inaccurate information shared without malicious intent. NATO’s defined category of information threats focuses on intentional, harmful, manipulative and coordinated activity, although misinformation can still cause harm. These distinctions are useful within NATO’s policy framework; they are not a universal rule for every organization or research discipline.
Disinformation concerns deliberate manipulation in NATO’s explanation. But an inaccurate, inflammatory or widely shared post does not, by itself, establish that a coordinated campaign exists or reveal who is behind it. Attribution requires evidence about behavior and connections. The U.S. Government Accountability Office’s 2024 report on foreign disinformation focuses mainly on foreign-government activity because that was the emphasis of the agencies and work it reviewed.
How can an organization detect a possible campaign?
NATO’s 2024 approach describes monitoring and assessing information threats as the basis for informed responses. Its ABCDE approach examines the actor, behavior, content, degree and effect. Used together, those dimensions help analysts distinguish a potentially coordinated effort from a single false claim or ordinary disagreement.
- Define the scope and the harm that matters. Identify the organizational assets, audiences and decisions that need protection, and specify what impact would justify investigation. Set boundaries that distinguish suspected manipulation from criticism, legitimate disagreement, isolated inaccuracies and false claims shared without malicious intent. NATO says its framework respects freedom of expression, pluralism, democracy and the rule of law.
- Monitor relevant sources within appropriate boundaries. NATO describes drawing on broad data sources to build an integrated view, supported by people, processes and technology. In its 2024 report, GAO says the U.S. State Department, Department of Homeland Security’s Office of Intelligence and Analysis, and Department of Defense use public and nonpublic sources; State and DHS I&A analyze social media to identify disinformation and actors. Those government practices are examples, not a blanket instruction or legal authorization for private companies to collect the same information.
- Assess the actor, behavior and content together. Check who appears to be participating, whether operators or affiliations are concealed, what narratives or claims are being shared, and whether activity shows recurring tactics or suspicious coordination. GAO describes fake accounts and websites with hidden operators or hidden foreign-government connections as tactics used to spread disinformation. A single signal does not prove who is responsible.
- Estimate degree and effect. Consider the scale and reach of the activity, the audiences it targets and the decisions or events it may affect. Examine whether online activity appears connected to cyber-enabled operations or physical events. Record what is observed separately from what remains an inference so that reach or timing is not mistaken for proof of impact.
- Use automated tools as aids, not arbiters. NATO says AI-enabled tools can support monitoring, analysis and assessment, while audience research can add empirical insights. It also notes that AI and deepfakes can be used to amplify manipulation and create confusion. Review automated flags against provenance, context and behavior; the cited sources do not establish an AI detector as a definitive test of falsity or hostile intent.
- Verify and route findings. Preserve relevant evidence, check provenance and context, assess likely impact, and bring the issue to the appropriate security, communications, legal or leadership roles. NATO emphasizes interoperability, structured information sharing and timely, actionable assessments. Use only data collection and response practices that are appropriate under the rules applicable to your organization and jurisdiction.
- Respond proportionately and learn from the outcome. NATO describes four response functions: understand; prevent; contain and mitigate; and recover. Depending on the evidence and likely harm, possible measures include early warning, proactive communication, awareness and resilience work, coordinated public statements, corrections, debunking and countering hostile narratives. Assess vulnerabilities exploited during an incident. Avoid giving a low-reach claim unnecessary visibility simply by repeating it.
What evidence should analysts look for?
A useful assessment separates observations from conclusions and records the basis for each. For example, several accounts posting similar material at similar times may be an observable pattern; a conclusion about who coordinated them requires further evidence. NATO’s framework emphasizes tactics, techniques and procedures, patterns of behavior, effects and the wider hybrid-threat environment rather than treating an isolated message as decisive.
Rank #3
- Actor: What is known about the accounts, organizations or operators involved? Is there evidence of concealed control or affiliation?
- Behavior: Does activity show repeated tactics, synchronized posting or other coordination? Is there evidence connecting it to cyber-enabled activity or events outside the information environment?
- Content: What is being communicated, and what can be established about its provenance and accuracy? Is the content part of a wider pattern?
- Degree: How extensive is the activity, and which audiences or channels does it reach?
- Effect: What decision, audience or organizational function may be affected, and what evidence supports that assessment?
These questions organize an inquiry; they do not turn any one answer into proof of a hostile campaign. Conclusions about intent and attribution should reflect the strength and limits of the available evidence.
How should organizations compare detection approaches?
There is no single tool or monitoring setup established by the cited sources as right for every organization. When evaluating an approach—whether internal or supported by technology—compare what it can actually do and how its findings lead to decisions.
| What to assess | Questions to ask |
|---|---|
| Coverage and access | Which sources can it assess, and are they appropriate and lawfully accessible for the organization’s purpose? |
| Coordination and content | Can it identify patterns of actor behavior as well as analyze individual claims or items of content? |
| Scale and impact | Can analysts assess degree, audience reach and potential effects rather than relying on volume alone? |
| Context and review | Can a human reviewer inspect provenance, behavior and context behind an alert? |
| Actionability | Do findings reach responsible decision-makers in time, and can relevant information be shared in a structured way? |
| Response and recovery | Does the organization have a defined path from assessment to proportionate response and post-incident learning? |
NATO’s approach identifies broad data sources, integration of people, processes and technology, interoperability and actionable insights as elements of effective assessment. Those principles can inform an organizational review without implying that every organization needs the same sources, systems or staffing.

Government detection practices are not a ready-made compliance manual for private organizations. Before collecting information or acting on findings, an organization should check the privacy, employment, election, security and speech rules that apply in its jurisdiction. The sources described here do not establish jurisdiction-specific legal advice.
Best Value
Terminology also matters. When discussing a suspected incident, name the framework being used—such as NATO’s information-threat terminology or the U.S. military definition of information operations—and describe what the evidence supports. This avoids presenting a contested phrase as though it had one settled meaning across policy, military doctrine and public discussion.
