Today we are living in a global village. We have facilities like science, technology which have developed inter-connecting bonds among different countries on the globe. The science is working in the direction of making human life more comfortable and better than last decades. The technology has made life smoother, faster, and simpler. Through it, the single bit of information can be easily transmitted within seconds from one computer system to another around whole of the world. Gone are the days when we tried to communicate through post letters, fax machines and telephones. Now we have achieved our dreams. We have various facilities such as video chat, telemedicine, movies on demand, relay chat rooms, various e-business models which reminds us that distance and time barriers of communications are no more these days. One can enjoy all these benefits but this bright has dark side as well too. There are lots of threats which are dangerous for information security on the computer network such as phishers, hackers, viruses etc. A large portion of our system experts’ efforts, their systems’ energies, time, and investments are consumed by these security threats and their fixation. We are continuously working for the development of strong information security system with minimum amount of wastage for the efforts made. The objective of this paper is to discuss about the information security and the defense mechanisms used by it against security threats.
