Client honeypots are security devices designed to find servers that attack clients. High-interaction client honeypots (HICHPs) classify potentially malicious Web pages by driving a dedicated vulnerable Web browser to retrieve and classify these pages.

In this paper we propose a new architecture, which is composed of distributed cooperative agents to reduce the false alarm ratio of the intrusion detection systems (IDS) in a twofold contribution. The first contribution lies in reducing the false alarm rate of the attack detection in an agent-based architecture by using honeypot network as the closer level of investigation. The connection is retrieved...
To solve security problems of E-commerce system, this paper proposed a new trust model APR which is based on anticipative perceived risk. The concept of perceived risk was introduced into APR, many kinds of trust factor were taken to calculate the trust value among nodes, and an origination method was provided to integrate direct trust and recommendation trust.
