CANtropy: Time Series Feature Extraction-Based Intrusion Detection Systems for Controller Area Networks

This repository provides the python implementation of CANtropy, a manual feature engineering-based lightweight CAN IDS. For each signal, CANtropy explores a comprehensive set of features from both temporal and statistical domains and selects only the effective subset of features in the detection pipeline to ensure scalability. Later, CANtropy uses a lightweight unsupervised anomaly detection model based on principal component analysis, to learn the mutual dependencies of the features and detect abnormal patterns in the sequence of CAN messages. The evaluation results on the advanced SynCAN dataset show that CANtropy provides a comprehensive defense against diverse types of cyberattacks.

Create Symbolic Link (Optional)

If you have the the datasets downloaded (or want to download) outside of the repo, you can create a symbolic link to show the those dataset folders wihtin the repository. To create symbolic link from the repository's directory:

cd <directory_to_cantropy>
ln -s <directory_to_syncan_dataset>/ datasets/
ln -s <directory_to_road_dataset>/ datasets/

For example, if /home/workspace/can-ids-datasets/ folder contains the SynCAN and ROAD dataset, you can follow:

cd cantropy
ln -s /home/workspace/can-ids-datasets/syncan datasets
ln -s /home/workspace/can-ids-datasets/road datasets

Implementing cantropy

Feature Extraction

python run_feature_extraction.py --config-name <dataset_name> -m data_type=training,testing

• For Example:

  python run_feature_extraction.py --config-name syncan -m data_type=training,testing
  
  python run_feature_extraction.py --config-name road -m data_type=training,testing

Feature Analysis and Evaluation

python run_feature_analysis.py --config-name <dataset_name>

• For Example:

  python run_feature_analysis.py --config-name syncan
  
  python run_feature_analysis.py --config-name road

Unit Test

• To run the scripts on a smaller fraction of dataset add the argument fraction=<any fraction within 0.0 to 1.0>

• For instance, to run the scripts on the first 10% of the data points (both training and testing):

  python run_feature_extraction.py --config-name syncan -m data_type=training,testing fraction=0.10
  python run_feature_analysis.py fraction=0.10

  python run_feature_extraction.py --config-name road -m data_type=training,testing fraction=0.10
  python run_feature_analysis.py fraction=0.10

Visualization and Results

• The figures are saved in artificts/figures folder.
• The results are saved in artificts/results folder.
