Abstract:
Systems and methods perform selective rate limiting with a distributed set of agents and a remote controller. An agent receives a packet from a client, and inspects the packet using different rules. Each rule may include at least one different (i) rule definition with traffic dimensions identifying a different attack, (ii) signal with which to identify attack traffic matching the rule definition, (iii) threshold specifying a condition, and (iv) action to implement based on the condition of the threshold being satisfied. The agent provides the signal in response to the packet matching the traffic dimensions from the rule definition of a particular rule. The controller updates a value linked to the signal and a client identifier of the client, and implements the action of the particular rule across the distributed set of agents in response to the value satisfying the condition for the particular rule threshold.
