Cyber warfare and the laws of war

The use of cyberspace as an operational domain to wage war emerged with the development of the internet in the latter part of the twentieth century. An increased reliance on the internet as the primary information infrastructure to undertake both civilian and defence affairs has made it more attractive as a target and as a domain to carry out attacks. Cyber warfare ceased to be science fiction even in the twentieth century, with suspected cyber-attacks taking place in the 1990s. Dr Heather Harrison Dinniss presents readers with a wellresearched work in her book Cyber Warfare and the Laws of War, about the changing landscape of conflict, where ‘cyber-bullets’ are found to have a more lethal effect than a conventional rocket fired from a launcher, with battles raging in cyberspace. Dinniss’ book seeks to contribute to the debate on the subject, by presenting a systematic analysis of the laws of armed conflict – both jus ad bellum and jus in bello – as they relate to cyber warfare.
