In recent years, distributed denial-of-service (DDoS) and denial-of-service (DoS) are the most dreadful network threats. Single-node IDS often suffers from losing its detection effectiveness and capability when processing enormous network traffic. To solve the drawbacks, we propose grid-based IDS, called grid intrusion detection system (GIDS), which uses(More)
Distributed denial-of-service (DDoS) and denial-of-service (DoS) are the most dreadful network threats in recent years. In this paper, we propose a grid-based IDS, called performance-based grid intrusion detection system (PGIDS), which exploits grid's abundant computing resources to detect enormous intrusion packets and improve the drawbacks of traditional(More)
Network-based intrusion detection system (NIDS) is developed to monitor network traffic in order to detect network intrusion. But it often lacks global cooperative capability. When facing attacks, e.g., DDoS, an intrusion detection system (IDS) needs an overall scheme to respond properly. Also, Internet consists of network management units (NMUs). It would(More)
In this article, we proposed an intrusion prevention system, named Cumulative-Sum-based Intrusion Prevention System (CSIPS) which detects malicious behaviors, attacks and distributed attacks launched to remote clients and local hosts based on the Cumulative Sum (CUSUM) algorithm. Experimental results show that CSIPSs in a united defense environment can(More)
In this article, we propose a fault-tolerant and grid-based IDS, named fault-tolerant grid intrusion detection system (FGIDS) which exploits grid's dynamic and abundant computing resources to detect malicious behaviors from a massive amount of network packets. In FGIDS, a detector can dynamically leave or join FGIDS anytime. A newly joined one is tested to(More)
Communication protocol is an important mechanism in mobile agent systems since agents need to communicate each other to clinch and achieve their joint goal In this research, we investigate communication issues between mobile agents, and propose a reliable communication protocol which integrates Session Initiation Protocol (SIP) as signaling protocol.
