In past few years due to the increase in access of malicious data over the Internet resources the security becomes a necessary component. Swarm intelligence is an emerging and new biological field of optimization. The researchers have already developed many algorithms by studying the behavior of different swarms of incest such as Ants Bees etc. After the success of swarm intelligence in other areas researchers now started work in the field of security too. In this survey paper we tried to find out the reason of network security and how swarm intelligence method have been used to make system efficient in term of performance by providing network security.. Keywords: Network Security, Swarm Intelligence, Ant Colony Optimization (ACO), Particle Swarm Optimization (PSO), Ant Colony Clustering (ACC), Survey 1. INTRODUCTION The use of computer and Internet is increasing day by day and they both can bring significant changes in the quality of life style of many people. In the last few years, different techniques were proposed and successfully deployed to secure the computer systems from unauthorized use. Such techniques include additional software and hardware systems like anti- virus software, firewall, secured network protocols, password protection, message encryption, M.S. Iftikhar and M. R.
