Network Intrusion Detection System Embedded on a Smart Sensor

This paper proposes a Network Intrusion Detection System (NIDS) embedded in a smart-sensor-inspired device under a service-oriented architecture (SOA) approach which is able to operate independently as an anomaly-based NIDS, or integrated transparently in a Distributed Intrusion Detection System (DIDS). The proposal is innovative because it combines the advantages of the smart sensor approach and the subsequent offering of the NIDS functionality as a service with the SOA use to achieve their integration with other DIDS components. The main goal of this paper is to reduce the huge volume of management tasks inherent to this type of network services, as well as facilitating the design of DIDS whose managing complexity could be restricted within well-defined margins. This paper also addresses the construction of a physical sensor prototype. This prototype was used to carry out the tests that has demonstrated the proposal´s validity, providing detection and performance ratios similar to those of existing intrusion detection systems (IDS), but with the advantage of a zero-maintenance approach.
