Abstract
A computer-implemented method for transformation of security information and event management (SIEM) rules and deploying the SIEM rules in a network of event processors. A computer system or server converts the SIEM rules to formal representations. The computer system or server generates rule abstraction of the formal representations, by using an abstraction function. The computer system or server constructs a finite automaton based on the rule abstraction. The computer system or server eliminates irrelevant transitions in the finite automaton to generate an optimized finite automaton. The computer system or server generates optimized formal rules, based on the optimized finite automaton. The computer system or server converts the optimized formal rules to optimized SIEM rules. The computer or server deploys the optimized SIEM rules in the network of the event processors.
