Abstract
A system and method for performing source path isolation in a network. The system comprises an intrusion detection system (IDS), a source path isolation server (SS) and at least one router configured to operate as a source path isolation router (SR) operating within an autonomous system. When IDS detects a malicious packet, a message is sent to SS. SSin turn generates a query message (QM) containing at least a portion of the malicious packet. Then, QM is sent to participating routers located one hop away. SRuses the query message to determine if it has observed the malicious packet by comparing it with locally stored information about packets having passed through SR. SRsends a reply to SS, and SSuses the reply to identify the ingress point into the network of the malicious packet.
