WebIn this paper, we take advantage of the feature that the power spectral density (PSD) of LDoS attacks in low frequency band is higher than normal traffic’s to detect whether there are LDoS attacks. We put forward a detection method based on the Bartlett spectral estimation approach and discuss its feasibility from two aspects, the esti- mation … WebThe first parameter, µ, is the mean. The second parameter, σ, is the standard deviation. The standard normal distribution has zero mean and unit standard deviation. The normal …
