A performance model to Cooperative Itinerant Agents (CIA): a security scheme to IDS

Abstract

Intrusion detection systems (IDS) based on autonomous agents are important security tools to protect distributed networks and they can be considered critical systems. For this reason; we have proposed a security scheme to verify the entities' integrity inside the IDS architecture named cooperative itinerant agent (CIA). The proposal includes software watermarking and fingerprinting techniques. Moreover, in this paper we infer a formula to calculate the time consumed by a CIA to perform entities' verification in a determined level of the infrastructure in order to evaluate the agent's scalability. The parameters of this formula are the network's throughput and delay
