Technique of detecting denial of service attacks |
摘要 |
The invention detects a denial of service attack at a node by monitoring the number of discarded packets in relationship to the number of inbound packets. When an attack is detected, relevant inbound packet information is collected during the attack to help characterize the attack and at least to pinpoint the source of the last hop to the attacked node.
