Total System Assurance (TSA) deals with assuring the security of all system components by considering all potential risks. This comprehensive approach to system assurance tackles security from multiple points of views, thus ensuring the highest possible level of assurance. In this paper, the authors illustrate the TSA approach by considering a complex system running a Mobile Agent-based Wireless Sensor Network (MA-WSN). Security in WSNs has been addressed extensively in the literature, however a comprehensive and integrative system security and assurance has not been considered. Total assurance in MAWSN applications relies on the security of the mobile agents, and the mobile agent platform, in addition to the security of the wireless sensors and the application servers.
