MULTI-TIERED APPROACH TO DETECT AND MITIGATE ONLINE ELECTRONIC ATTACKS

摘要

A triaged approach is implemented to detect and prevent electronic attacks against online entities and to reduce latency. Transaction requests are classified into different tiers and are treated differently based on the tier status. For example, transaction requests to conduct transactions with an entity are received from a client system. Characteristics such as rate or amounts of transactions of the transaction requests are analyzed. The characteristics are compared against specified threshold limits to assess whether the specified threshold limits are exceeded. Based on an assessment that at least one of the specified threshold limits is exceeded, a set of computer instructions is selected from different sets of computer instructions for execution on the client system. A result of an execution is received from the client system. Based on the result of the execution, a determination is made whether the transaction requests appear to have originated from a machine-automated submission process.
