International Humanitarian Law (IHL), also known as the law of armed conflict or the law of war, is a set of rules that seek to limit the effects of armed conflict for humanitarian reasons. It protects people who are not participating in the hostilities, such as civilians, medical personnel, and aid workers, and restricts the means and methods of warfare. IHL is primarily composed of the Geneva Conventions and their Additional Protocols, as well as other international treaties and customary law. In the context of cybersecurity, IHL is increasingly relevant as cyber operations become part of modern warfare, raising questions about the protection of civilian infrastructure and the application of existing legal norms to digital attacks.
