Security means to provide protection from any danger, security, crime or loss that can be inflicted. Security measures are taken everywhere, to keep the resources and arrangement orderly and in place. Providing security at events is a way of being proactive to deal with any kind of mishaps. Security deals with concepts such as safety, continuity and reliability. In simple terms, the condition or state of being secure is called security. Security is a means of reducing risk, apprehension and care. National security is the duty of the defence personnel and forces always at the border, fighting for the nation and protecting it from immigrants. Barrack Obama had remarked, “When we think of the major threats to our national security, the first to come to mind are nuclear proliferation, rogue states and global terrorism. But another kind of threat lurks beyond our shores, one from nature, not humans - an avian flu pandemic.”
