Abstract
A malicious encrypted traffic detector connected to a computer network, the detector comprising: a Shannon entropy estimator; an entropy comparator; a store storing a reference measure of Shannon entropy of a portion of network traffic of a malicious encrypted network connection, wherein the estimator is adapted to estimate a measure of entropy for a corresponding portion of network traffic communicated over the computer network, and the entropy comparator is adapted to compare the estimated measure of entropy with the reference measure so as to determine if malicious encrypted network traffic is communicated over the network connection.
