The main aim of the state is to maintain its cyberspace free from espionage and other malicious activities. USA, China, Russia are some of those countries whose cyberspace is well protected then any other countries round the globe. In these countries the reliance of military units is very high which gives the possibility of invention of fifth dimension for war. The cyber operations today holds the greatest importance of any other matter, because being dynamic in nature it aims at directly disrupting the infrastructures and many other vital elements of the state. The hackers in Estonia and Georgia made great use of the opportunities given to them, and a simple looking cyber-operation resulted in armed conflict situation, that is why the concept of these cyber operations is now rapidly changing to cyber-warfare activities. There is now the need for more effective and efficient cyberspace so that the strike of future cyber-warfare and its impact could be minimized. International Law is still in its growing prospect. Many elements of international law lies in ambiguity, how it can be developed is the main aim of this article. In some instances the Cyberspace setup has really out bounded the hackers and other malicious activities, but that are really low in count. The concept of 'armed attack' and 'force' present in UN Charter creates really the vague concept of these terms in context to the International law.The legal implications that will follow the cyber-attack are really important that could only be understood when observed in relation to international law. This article focuses on the relationship between the international law and cyber-warfare. The legal lessons that have been learned by cyberspace authorities and legal bodies in relation to case studies. The nature and criterion of these cyber-warfare are all discussed thoroughly in this article. The standing of international law in this context is also analytically discussed by me.
