1. A computer-implemented method of surveillance of a first plurality of packets of data in a distributed computer network of an organization, said method executing computer program instructions stored in a non-transitory storage medium and comprising the steps of:

  • (a) analyzing a protocol of said data;

    (b) analyzing a user-behavior of a user of said distributed computer network;

    (c) analyzing a content of each packet belonging to said first plurality of packets of said data by utilizing deep packet inspection (DPI);

    (d) establishing a baseline of said data by assigning said each packet to a cluster of said packets amongst a first plurality of clusters of said packets of said data;

    (e) computing an overall score of said each packet along axes comprising said protocol, said user-behavior and said content;

    (f) based on said overall score, computing an absolute distance between said each packet and a center of said cluster of said packets of said data;

    (g) performing said assigning by minimizing an objective function given by a value computed by squaring said absolute distance and summing said value across said first plurality of said packets of said data and further summing said value across said first plurality of said clusters of said packets of said data; and

    (h) performing steps (a) through (g) in a master device of said distributed computer network and communicating said baseline to an agent device of said distributed computer network.
