Abstract
A method for filtering attack streams targeting a connectivity module receiving a plurality of incoming connection streams includes: determining a plurality of aggregates; determining a plurality of first measurement vectors; determining another aggregate resulting from the combination of a plurality of incoming connection streams during another time period; determining another first measurement vector associated with the other aggregate; determining an abnormality score depending on the result of projecting the other first measurement vector and projecting the plurality of first measurement vectors and then, if the abnormality score is comprised in an area of doubt regarding the presence of an attack stream determining a plurality of second measurement vectors, each associated with one of the aggregates; determining another second measurement vector associated with the other aggregate; and detecting the presence or absence of an attack by analysing the other second measurement vector.
