Abstract
Discussed herein are devices, systems, and methods for detecting anomalous or malicious processes based on a network session. A method includes receiving a network session, implementing a stacked hierarchical agglomerative clustering (HAC) algorithm that operates multiple HAC algorithms to identify respective clusters to which the network session maps, each HAC algorithm of the StackHAC algorithm operates using a different linkage function and distance pair, appending the respective clusters from the multiple HAC algorithms to a feature vector representing the network session resulting in an augmented feature space, and determining, using a classifier or clustering model that operates using the augmented feature space as input, whether each of the network sessions is associated with a network intrusion.
