Abstract: Apparatus for filtering transactions transmitted from a source to a protected entity, comprising: a transaction filter enforcer which receives a layer 7 transaction destined for a protected application prior to the transaction possibly being supplied to the protected entity; and an evaluator receiving the transaction from the enforcer; the enforcer routing the transaction to the protected entity when the transaction does not receive a determination as being malicious from the evaluator; the evaluator including at least a model that determines a score indicative of the maliciousness of the transaction based on input from at least one trained model, the transaction being supplied to each of the at least one trained model, each of which is a model from a set of model types, the model types including an anomaly model and an attack model; the enforcer operating in real-time and the evaluator operating in at least near real-time.

Abstract: A device and method for configuring a web application firewall (WAF) based on characterization of web attacks are provided. The method includes receiving a plurality of hypertext transfer protocol transactions (HTTP) entities; tokenizing the received plurality of HTTP entities based on at least one delimiter; analyzing statistical distribution of each of the at least one delimiter in the tokenized HTTP entities; training a model based on an analysis of the tokenized HTTP entities, when a sufficient number of HTTP entities have been analyzed; and configuring, based on the trained model, the WAF with at least one detection rule to detect at least malicious HTTP transactions.

Abstract: A system, and method therefor for disaggregated detection denial-of-service (DDoS) are provided. The system includes a plurality of detectors deployed on a plurality of network nodes, wherein each network node is connected to an edge network, wherein one detector of the plurality of detectors is deployed in each of the plurality of network nodes, wherein each of the plurality of detectors is configured to detect and characterize at least a DDoS attack by analyzing telemetries received by the respective network node in which the detector is deployed.
