Dynamic balancing of security rules execution in a database protection system

Abstract:

A database protection system (DPS) is configured to dynamically-optimize security rule validation throughput based on evaluating resource consumption data collected from prior validations. In particular, the DPS analyzes collected resource consumption information and determines which security rules in a set should then be active. To this end, the DPS is configured with multiple security rules engines (SREs), and each is configured to evaluate the same set of security rules. When an SRE applies a validation (to a request or response flow), an associated collector collects and analyzes associated resource consumption data. This data is provided to an optimizer, which receives similar resource consumption data from other SREs. Based on the resource consumption data collected from the SRE collector(s), the optimizer dynamically optimizes security rules validation in real-time, e.g., by dynamically switching on or off given security rule(s) in the set of security rules at given one(s) of the SREs.
