US Patent 9344457 Automated feedback for proposed security rules

A computer determines a number of matches returned by a proposed security rule that result from application of the proposed security-rule to historical logged event data. The computer determines a predicted performance of the proposed security rule as part of a network security system based on the number of matches. The computer sends a message during a creation session of the proposed security-rule. The message includes a recommended change for a portion of the proposed security based on the predicted performance of the proposed security rule.
