Abstract: For managing denial of service situations at an application level in a communications network receiving message data, the message data are monitored in a sensor that sends an event message when detecting an alarm condition; a control logic detects a first analysis to be performed associated with the received event message and generates a request; an analysis module receives the request of analysis, performs the analysis and sends a result message; the control logic receives the result message and detects an action to be taken associated with the result message, the action being a countermeasure or a further analysis. For determining the analysis to be performed and the action to be taken, the control logic browses rules stored in a memory, each rule including a conditional clause and an associated action to be taken.
