Security Analysis of Wireless Sensor Networks Using SIEM and Multi-agent Approach

The paper addresses the issue of providing information security to wireless sensor networks using Security Information and Event Management (SIEM) methodology along with multi-agent approach. The concept of wireless sensor networks and providing their information security, including construction of SIEM system architecture, SIEM analysis methodologies and its main features, are considered. The proposed approach is to integrate SIEM system methodology with a multi-agent architecture which includes data collecting agents, coordinating agent (supervisor) and local Intrusion Detection Systems (IDSs) based on artificial immune system mechanisms. Each IDS is used as an agent that performs a primary analysis and sends information about suspicious activity to the server. The server performs correlation analysis, identifies the most significant incidents, and helps to prioritize the incident response. The presented results of computational experiments confirm the effectiveness of the proposed approach.
