Patent ID: 11991205

Abstract:
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.
