An out-of-path defense platform protecting against excessive utilization of a cloud service providing a cloud hosted application comprising a controller communicatively coupled to a detector and a mitigator; wherein the detector receives telemetries from sources that are configured to collect telemetries related to the traffic between end user devices and an edge network that distributes traffic for the cloud hosted application, the telemetries being out-of-path information for traffic to and from the cloud-hosted application, wherein a portion of the telemetries relate to operation of a portion of a cloud computing platform hosting the cloud-hosted application, and detects, using the collected telemetries and a learned normal utilization behavior of each cloud service for the cloud-hosted application, excessive utilization of a cloud service by the cloud hosted application; and wherein the controller, upon detection of the excessive utilization, causes mitigation, by the mitigator, of the excessive utilization of each cloud service.

Techniques for protecting against excessive utilization of cloud services

A method and system for protecting cloud-hosted applications against application-layer slow DDoS attacks are provided. The system include a processing circuitry; and a memory connected to the processor, the memory contains instructions that when executed by the processing circuitry, configure the system to: collect telemetries from a plurality of sources deployed in a plurality of public cloud computing platforms, wherein each of the plurality of public cloud computing platforms hosts an instance of a protected cloud-hosted application; provide a set of rate-based and rate-invariant features based on the collected telemetries; evaluate each feature in the set of rate-based and rate-invariant features to determine whether a behavior of each feature and a behavior of the set of rate-based and rate-invariant features indicate a potential application-layer slow DDoS attack; and cause execution of a mitigation action, when an indication of a potential application-layer slow DDoS attack is determined.

Detection and mitigation of slow application layer DDoS attacks

A system and method for protecting cloud-hosted applications against hypertext transfer protocol (HTTP) flood distributed denial-of-service (DDoS) attacks are provided. The method includes collecting telemetries from a plurality of sources deployed in at least one cloud computing platform hosting a protected cloud-hosted application; providing at least one rate-based feature and at least one rate-invariant feature based on the collected telemetries, wherein the rate-based feature and the rate-invariant feature demonstrate behavior of at least HTTP traffic directed to the protected cloud-hosted application; evaluating the at least one rate-based feature and the at least one rate-invariant feature to determine whether the behavior of the at least HTTP traffic indicates a potential HTTP flood DDoS attack; and causing execution of a mitigation action when an indication of a potential HTTP flood DDoS attack is determined.

Detection and mitigation of flood type DDoS attacks against cloud-hosted applications

A defense platform for protecting a cloud-hosted application against distributed denial-of-services (DDoS) attacks, wherein the defense platform is deployed out-of-path of incoming traffic of the cloud-hosted application hosted in a plurality of cloud computing platforms, comprising: a detector; a mitigator; and a controller communicatively connected to the detector and the mitigator; wherein the detector is configured to: receive telemetries related to behavior of the cloud-hosted application from sources deployed in the plurality of cloud computing platforms; and detect, based on the telemetries, a potential DDoS attack; wherein, the controller, upon detection of a potential DDoS attack, is configured to: divert traffic directed to the cloud-hosted application to the mitigator; cause the mitigator to perform at least one mitigation action to remove malicious traffic from the diverted traffic; and cause injection of clean traffic to at least one of the plurality of cloud computing platforms hosting the cloud-hosted application.

Distributed denial of service (DDoS) defense techniques for applications hosted in cloud computing platforms

A method, system and a platform for protecting against excessive utilization of at least one cloud service for operation of a cloud-hosted application. The method comprising receiving, at a defense platform deployed out-of-path of traffic between a plurality of end user devices and the cloud-hosted application, telemetries from a plurality of sources, wherein each source is configured to collect telemetries related to at least one of the at least one cloud service; detecting, based on the collected telemetries and a learned normal utilization behavior for the cloud-hosted application, excessive utilization of at least one of the at least one cloud service by the cloud-hosted application; and causing mitigation, at the defense platform, of the excessive utilization of each cloud service upon detection of the excessive utilization of the at least one cloud service by the cloud-hosted application.

A method and system for protecting cloud-hosted applications against application-layer slow distributed denial-of-service (DDoS) attacks. The comprising collecting telemetries from a plurality of sources deployed in at least one cloud computing platform hosting a protected cloud-hosted application; providing a set of rate-based and rate-invariant features based on the collected telemetries; evaluating each feature in the set of rate-based and rate-invariant features to determine whether a behavior of each feature and a behavior of the set of rate-based and rate-invariant features indicate a potential application-layer slow DDoS attack; and causing execution of a mitigation action, when an indication of a potential application-layer slow DDoS attack is determined.
