A computerized method is disclosed that includes operations of obtaining network traffic data between a source device and a destination device, performing a regularity assessment of a first metric of the network traffic data across communication sessions of the source device and the destination device over a given time period by: determining an average of the first metric for each of the communication sessions; establishing an upper bound and a lower bound for the averages of the first metric over the given time period; determining a difference between the upper bound and the lower bound; comparing the difference between the upper bound and the lower bound to a mean of the first metric for each of the communication sessions over the given time period, and determining whether beaconing transmissions are present within the network traffic data based on the regularity assessment of the first metric.
