Collaborative Intrusion Detection Scheme for Network-Attached Storage Based on Agents

According to the various and complex intrusions in the network, this paper proposed a new collaborative intrusion detection scheme for Network-Attached Storage (NAS) based on agents. The new scheme utilizes the static agents and mobile agents to collect intrusion alerts which are generated by the single-node Intrusion Detection System. These intrusion alerts can be associated to build scenarios which represent the course and purpose of the hacker attacks. The experimental results demonstrate that the new scheme can protect the network storage devices efficiently with a little extra network traffic.
