An intrusion detection system (IDS) could be a device or software application that observes a network for malicious activity or policy violations. Any malicious activity or violation is often reported or collected centrally employing a security information and event management system. Some IDS’s are proficient of responding to detected intrusion upon discovery. These are classified as intrusion prevention systems (IPS). A system that analyzes incoming network traffic is thought as Network intrusion detection system (NIDS). A system that monitors important software files is understood as Host intrusion detection system (HIDS). Wireless sensor networks (WSNs) are vulnerable to different kinds of security threats which will degenrate the performance of the entire network; that may lead to fatal problems like denial of service (DoS) attacks, direction attacks, Sybil attack etc. Key management protocols, authentication protocols and secure routing cannot provide security to WSNs for these varieties of attacks. Intrusion detection system (IDS) could be a solution to the present problem. It analyzes the network by collecting sufficient amount of knowledge and detects abnormal behavior of sensor node(s).
