Abstract

Denial-of-service (DoS) and distributed denial-of-service (DDoS) are two of the most serious and destructive network threats on the Internet. Hackers, exploiting all kinds of malicious packages to attack and usurp network hosts, servers and bandwidth, have seriously damaged enterprise, campus and government network systems. Many network administrators employ intrusion detection systems (IDSs) and/or firewalls to protect their systems. However, some systems lose most of their detection and/or protection capabilities when encountering a huge volume of attack packets. In addition, some detection resources may fail due to hardware and/or software faults. In this paper, we propose a Grid-based platform, named the dynamic grid-based intrusion detection environment (DGIDE), which exploits Grid's abundant computing resources to detect a massive amount of intrusion packets and to manage a dynamic environment. A detector, a node that detects attacks, can dynamically join or leave the DGIDE. A newly joined detector is tested so that we can obtain its key performance curves, which are used to balance detection workload among detectors. The DGIDE backs up network packets. When, for some reason, a detector cannot continue its detection thus leaving an unfinished detection task, the DGIDE allocates another available detector to take over. Therefore, the drawbacks of ordinary security systems as mentioned above can be avoided.
