A system and method for detecting a Denial of Service (DoS) attack. A number of evaluator elements (M) is determined for DoS analysis for network connection requests wherein each evaluator element is preferably associated with a component of the analyzed connection request. A DoS evaluator element score is determined for an evaluator element of the connection request by analyzing the evaluator element. DoS mitigation actions may be performed on the connection request if the determined evaluator element score is indicative of a DoS attack. An evaluator consolidated score (which may be weighted) is then calculated preferably consisting of one or more of the respective DoS evaluator element scores. Next, a determination is made as to whether each evaluator element of the M evaluator elements has been analyzed for determining a respective DoS evaluator element score. If no, a DoS evaluator element score for a succeeding evaluator element to be analyzed is then determined. And if yes, a determination is then made as to whether the value of the evaluator consolidated score is indicative of a DoS attack by the subject analyzed network connection request.
