This work attempts to find out if existing international laws and practices can shed light and provide solutions to the existing issues arising from cyber warfare. This work consists of two parts. The first part deals with notions and definitions, which even now do not have a uniform understanding, among scholars and States alike. It also briefly touches upon attribution and technical difficulties, solving which would greatly enhance the situation with tracing and tracking cyber attacks. The second part is concerned with specific legal issues, firstly can current international laws accommodate cyber warfare within their framework, and secondly questions relating to self-defense against a cyber attack and combatancy are going to be answered. This part also deals with future prospects for cyber warfare regulation via an international cyber treaty.
