ABSTRACT:
A method and system are provided for use in detecting and preventing attacks in a communications network. In one example, the method includes calculating first and second traffic volumes based on messages received at a first time and a second time, respectively. An average acceleration is calculated based on the first and second traffic volumes, and the method identifies whether the average acceleration has crossed a threshold. The messages are serviced only if the average acceleration has not crossed the threshold.
