Legal personhood is the attribution of certain legal rights and responsibilities to entities other than natural human beings. In cybersecurity and law, this concept allows corporations, organizations, and potentially artificial intelligence systems to be recognized as 'persons' in the eyes of the law. This recognition enables these entities to own property, enter contracts, sue or be sued, and be held liable for actions. The extension of legal personhood to non-human entities raises important questions in cybersecurity, especially regarding accountability, liability, and the ethical use of AI. Understanding legal personhood is crucial when considering who is responsible for cyber incidents involving automated or organizational actors.
