Dataset used for An Evaluation of Machine Learning Models for Autonomous Adversary Emulation

The dataset within this repository is released in order to facilitate research regarding autonomous adversary emulation. The dataset was gathered by running Lore scenarios against a emulated IT-environment. For full description, please see paper X. For seven action categories a number of (feature, reward) samples are recorded. The task is to predict the reward.

For any questions about the dataset, please contact blinded-author.

Directory structure

We use the following ActionCategory and better explained name in the paper:

The directory training include the samples that can be used for training ML models. The directory evaluation include data about the tests used to provide a secondary evaluation of the trained models on a different IT environment and using a different Lore scenario configuration.

File descriptions training

For each type of action category, there is an associated feature-space meaning that we essentially require different models for the different categories. The description of the feature-space is found in the feature_schema.json. A excerpt is explained below. The structure of the dataset_compressed_for_ml.json is also explained below.

NetworkScanning - feature_schema.json

A subset of the feature groups and features in the feature groups for the Network Scanning category is found below. There are integers (either categorical or regular), floats, booleans and arrays.

NetworkScanning - dataset_compressed_for_ml.json

Each dataset_compressed_for_ml.json has the same structure. A results key with a list of rewards and a feature key with the features. The features dict has the same structure as the feature_schema.json with the features as a list of values. The n:th feature of each list correspond to the n:th reward.

{
    "results": [ float, float, float, float, ... ],
    "features": {
        "ConcernedAbstractAction": {    <---- feature group
            "concerned_abstract_action": [0, 0, 4300, 0, ...],

        },
