Abstract: Wireless sensor networks usually comprise of a large number of nodes which are geographically dis- tributed and are not physically connected. These nodes are frequently used to sense private data and can be necessary to transmit confidential and critical data. Hence it is important to provide security for wireless sensor networks. Research is still ongoing in this field and many models have been proposed for providing security. Looking into the symbiotic nature of biological systems can give us valuable in- sights for computer networks. Because of the analo- gies between network security and how the biotic components react to perceived threats in their sur- roundings, Bio-inspired approaches for providing se- curity in networks are interesting to evaluate . Many theories from nature such as swarm intelligence, ant colony optimisation (ACO), web spider defence, bird flocking, human immune system and so forth have been used to tackle various problems in the network- ing domain. In this paper, we intend to outline and categorize the various security attacks we encounter in a wireless sensor network and review the proposed conventional security mechanisms for them and also compare it with an alternative novel approach, i.e bio-inspired approach
