Evaluation of anomaly detection in imbalanced authentication logs.

1. Create a conda virtual environment

   conda create --name imbalance-anomaly python=3.6

2. Activate the environment

   conda activate imbalance-anomaly

1. Clone this repository

   git clone https://github.com/studiawan/imbalance-anomaly.git

2. Go to the project directory. The rest of the instructions run in this directory

   cd imbalance-anomaly

3. In setup.py file, change tensorflow-gpu to tensorflow if you do not run on a GPU

4. Install this package in the activated virtual environment

   pip install -e .

1. Copy the datasets from imbalance-anomaly-gt repository to directory imbalance-anomaly/datasets. It is assumed that the directory of both repository are located in ~/Git. Please change according to your own directory structure

   cp ~/Git/imbalance-anomaly-gt/datasets/casper-rw/log.all.pickle ~/Git/imbalance-anomaly/datasets/casper-rw/log.all.pickle

   cp ~/Git/imbalance-anomaly-gt/datasets/dfrws-2009/log.all.pickle ~/Git/imbalance-anomaly/datasets/dfrws-2009/log.all.pickle

   cp ~/Git/imbalance-anomaly-gt/datasets/honeynet-challenge7/log.all.pickle ~/Git/imbalance-anomaly/datasets/honeynet-challenge7/log.all.pickle

2. Extract the Glove pre-trained embedding

   tar -xzvf glove/glove6B.50d.tar.gz --directory glove/

1. Run experiments for all methods from Keras library. Type dataset name and method name after the script. The supported datasets are casper-rw, dfrws-2009, and honeynet-challenge7. The supported methods are lstm and cnn.

   Command:

   python imbalance_anomaly/experiment/experiment_keras.py dataset_name method_name

   Example:

   python imbalance_anomaly/experiment/experiment_keras.py casper-rw lstm

2. The experimental results are located in imbalance_anomaly/datasets/$DATASET_NAME$/ where $DATASET_NAME$ is one of the datasets: casper-rw, dfrws-2009, and honeynet-challenge7. The file name format for experimental results is $METHOD_NAME$.evaluation.csv.

3. Pretty print the csv file of experimental results

   column -s, -t datasets/$DATASET_NAME$/$METHOD_NAME$.evaluation.csv
