DeepCASE

This repository contains the code for DeepCASE by the authors of the IEEE S&P DeepCASE [1] paper [PDF]. Please cite DeepCASE when using it in academic publications. This main branch provides DeepCASE as an out of the box tool. For the original experiments from the paper, please checkout the sp branch.

Introduction

DeepCASE introduces a semi-supervised approach for the contextual analysis of security events. This approach automatically finds correlations in sequences of security events and clusters these correlated sequences. The clusters of correlated sequences are then shown to security operators who can set policies for each sequence. Such policies can ignore sequences of unimportant events, pass sequences to a human operator for further inspection, or (in the future) automatically trigger response mechanisms. The main contribution of this work is to reduce the number of manual inspection security operators have to perform on the vast amounts of security events that they receive.

Documentation

We provide an extensive documentation including installation instructions and reference at deepcase.readthedocs.io.

Dataset

This research uses two datasets for its evaluation:

Lastline dataset.
HDFS dataset.

NOTE

The Lastline dataset was obtained under an NDA and therefore, unfortunately, we cannot share the dataset.

For more details, please see the data directory of this repository.
