Intrusion detection is the process of identifying suspicious activities on a target system or network. A lot of approaches have been proposed for building better Intrusion Detection Systems. Some of the approaches use signature based, some use anomaly based and some use both. Most of the real time systems use signature based techniques. Main problem with signature based technique is its vulnerability...
DDOS attacks generate flooding traffic from multiple sources towards selected nodes and cause obstruction in flow of legitimate information within a network. If the victim node is the server at ISP level requiring fast information processing, the entire network operation stops. We use various lines of honeypot based defense against such attacks. The first line of defense detects the presence of attacks...
High bandwidth DDoS attacks consume more resources and have direct impact at ISP level in contrast to low rate DDoS attacks leading to graceful degradation of network and being mostly undetectable. Although an array of detection schemes have been proposed, current requirement is a real time DDoS detection mechanism that adapts itself to varying network conditions to give minimum false alarms. We treat...
