This paper gives a close look to the very important aspect of human security in today’s world of globalization and information cyber security. The role of social media, cyber security and cyber terrorism are dealt in the paper. We are witnessing a worldwide technological boom, wherein highly sensitive Government data to minute details of everyday life is digitally handled. Rules of warfare are changing and there is no longer a need for well-equipped brigade of foot soldiers to wage a war. Modern warriors, also known as hackers have the ability to hack into computer systems that can collapse networks and cause both human and infrastructural loss. Social media is a great facilitator. It has not only brought people together. But since the number of internet users in world is growing, no doubt, the number of social media users is also on the increase. It was revealed that Social networking sites permit for information to spread very quickly amongst the public. One of the biggest threat of technological warfare is that no one can really predict the time and source of the miscreant activity. It can be remotely initiated, and a lot of times the repercussion of the infringement is only realized after a considerable damage. Although, respective Government of world’s nation are spending a great deal of resources and effort to protect their data and information from falling into wrong hands, the onslaught of social media porches namely Facebook, Twitter, YouTube and emergence of non-profit media organizations such as the WikiLeaks, who have a track record of exposing undisclosed Government information on public domain are making such efforts difficult. These trends are posing a threat to human security, and there is a need for greater Government security and awareness amongst citizens to safeguard their information on the World Wide Web.
