Abstract
Embodiments defend a node in a network, e.g., a server or website, against distributed denial of service (DDoS) attacks through use of a criterion of discrimination between messages that the defended network node considers important to receive, and all other messages addressed to the defended network node. The use of this new criterion upends the conventional approach to defense against DDoS attacks. Whereas the conventional defense methods attempt to identify attack packets in order to drop them, embodiments identify packets that comply with an indication of packets defined as important by the defending server, as determined by a verification performed using the criterion of discrimination, thus making sure the compliant packets are delivered to their destination, while providing functionality for all other packets (those not identified as compliant) to be dropped.
