Three-Level detection algorithm is provided to detect low-rate denial of service attacks. The networks abnormities are caught in the first level; In the second level the flooding and low-rate denial of service(DoS) are divided; And then the Low-Rate DoS is detected accurately using frequency transfer method in the third level. Considering the application of networks, Low-Rate DoS attacks are detected and confirmed in Three-Level detection algorithm. Comparing with single level detection method, the most complex procedure is left behind to reduce detecting overhead. The simulation results certificate the feasibility of the algorithm.
