AntiNex REST API¶

Automate training AI to defend applications with a Django 2.0+ REST Framework + Celery + Swagger + JWT using Keras and Tensorflow.

Now supports building the same highly accurate deep neural networks as the AntiNex Core (99.8% accuracy with Django, Flask, React + Redux, Vue and Spring). This repository is fully dockerized and after the django celery worker finishes processing, it will auto-push predictions to the core’s celery worker which is decoupled from django and the django database. The core’s celery worker stores pre-trained AI neural networks in memory for faster predictions and supports re-training models as needed.

For those wanting to scale up their processing speeds, AntiNex deploys on OpenShift Container Platform and Kubernetes with persistent database volumes for Postgres (Crunchy Data) and Redis (Bitnami)

Supported API Requests¶

This repository was built to help capture non-attack network traffic and to improve the accuracy of the Keras + Tensorflow Deep Neural Networks by providing them a simple multi-tenant REST API that has Swagger + JWT authentication baked into a single web application. By default, all created Deep Neural Networks are automatically saved as JSON including model weights. It also does not require a database (unless you want to set it up), and will be scaled out with Celery Connectors in the future. Please refer to the Network Pipeline repository for more details. This Django application server also comes with a functional Celery worker for running heavyweight, time-intensive tasks required for asynchronous use cases. This is good for when you are trying to train a deep net that takes a few minutes, and you do not want your HTTP client to time out.

I plan to automate the tests in a loop and then release the captured HTTP traffic to compile the first non-attack dataset for pairing up with the OWASP attack data which is already recorded and available in:

https://github.com/jay-johnson/network-pipeline-datasets

Update: 2018-02-25 - These merged datasets and accuracies are now available in the repository:

https://github.com/jay-johnson/antinex-datasets

Watch Getting Started¶

Assuming your host has the pips already cached locally this takes about a minute.

Install¶

Tested on Ubuntu 17.10, Ubuntu 18.04 and works on OpenShift Container Platform with Kubernetes.

mkdir -p -m 777 /opt/antinex
git clone https://github.com/jay-johnson/train-ai-with-django-swagger-jwt.git /opt/antinex/api
cd /opt/antinex/api
./install.sh

Getting Started With Docker¶

You can run without these optional steps and just use the default SQLite database. If you want to use docker and download all the containers, you can use the compose.yml file to start all of the containers and download the latest ai-core docker image which is ~2.5 GB on disk (built with Dockerfile and stored on Docker Hub).

To start all run:

# if you do not have docker compose installed, you can try installing it with:
# pip install docker-compose
./run-all.sh

Verify the containers started

Register the Postgres server
1. Right click on “Servers” and then “Create Server”
2. On the “General” tab enter a name like “webapp”
3. On the “Connection” tab enter:
  
  Host: postgres
  
  Username: postgres
  
  Password: postgres
4. Click “Save password?” check box
5. Click the “Save” button
6. Navigate down the tree:
  
  Servers > webapp (or the name you entered) > Databases > webapp > Schemas > public > Tables
7. Confirm there’s database tables with names like:
```
pipeline_mljob
pipeline_mljobresult
pipeline_mlprepare
```

Start¶

By default, this project uses gunicorn to start, but you can change to uwsgi by running export APP_SERVER=uwsgi before starting. Both app servers should work just fine.

Note: if you are running the docker “full stack” please make sure to run: export USE_ENV=drf-dev before starting the django application, or you can use run-django.sh which should do the same as start.sh.

./start.sh

Create a Highly Accurate Deep Neural Network for Protecting Django¶

This is the same API request the core uses to build the Django DNN with an accuracy of 99.8%:

https://github.com/jay-johnson/antinex-core#accuracy-and-prediction-report

with Notebook:

https://github.com/jay-johnson/antinex-core/blob/master/docker/notebooks/AntiNex-Protecting-Django.ipynb

./create-keras-dnn.py -f ./scaler-full-django-antinex-simple.json

Train and Predict with just a Dictionary List of Records¶

This will send a list of records to the API to train and make predictions. This mimics the live-prediction capability in the core for reusing pre-trained DNNs to make predictions faster. I use it to send the newest records to predict, so I do not have to generate lots of csv files everywhere + all-the-time.

./create-keras-dnn.py -f ./predict-rows-scaler-full-django.json

Train and Predict using the AntiNex Core¶

This will train and cache a deep neural network using the AntiNex Core. Once trained, the core can make future predictions with the same API call without having to retrain. This makes predictions much faster.

./create-keras-dnn.py -f only-publish-scaler-full-django.json

The core trains a deep neural network and persists it in a dictionary that uses the label value on the request to store the trained model. Future predictions must continue to reuse the same label value on the request to avoid waiting for a retraining cycle. Here is the label value used in the previous request which is:

"label": "Full-Django-AntiNex-Simple-Scaler-DNN"

Make Predictions for a List of Records¶

If you have a list of records the API, Worker and Core support making predictions for each record in a list.

Predict using the AntiNex Worker:

./create-keras-dnn.py -f predict-rows-scaler-full-django.json

Predict using the AntiNex Core:

./create-keras-dnn.py -f only-publish-predict-rows-simple.json

Advanced Naming for Multi-Tenant Environments¶

Problems will happen if multiple users are sharing the same host’s /tmp/ directory with the default naming conventions. To prevent issues, it is recommended to change the output dataset directory to separate directories per user and to make sure the directories are accessible by the Django server processes. Here’s an example of changing the output directory to my user which triggers the custom name detection. This detection means I will see logs for the training command to run with my newly generated dataset and metadata files:

mkdir /opt/jay
export OUTPUT_DIR=/opt/jay/
./build-new-dataset.py

...

Train a Neural Network with:
./create-keras-dnn.py /opt/jay/cleaned_attack_scans.csv /opt/jay/cleaned_metadata.json

If changing the output directory is not possible, then users will need to make sure the file names are unique before running. Here’s an example naming strategy for the csv datasets and metadata files to prevent collisions. The build-new-dataset.py script will also suggest the training command to run when you activate custom names:

Prepare a Named Dataset¶

./build-new-dataset.py /tmp/<MyFirstName>_$(date +"%Y-%m-%d-%H-%m-%N")_full.csv /tmp/<MyFirstName>_$(date +"%Y-%m-%d-%H-%m-%N")_readytouse.csv

Example that shows the suggested training command to run using the named dataset files on disk:

./build-new-dataset.py /tmp/jay_$(date +"%Y-%m-%d-%H-%m-%N")_full.csv /tmp/jay_$(date +"%Y-%m-%d-%H-%m-%N")_readytouse.csv

...

Train a Neural Network with:
./create-keras-dnn.py /tmp/jay_2018-02-05-21-02-274468596_readytouse.csv /tmp/cleaned_meta-54525d8da8a54e9d9005a29c63f2918b.json

Confirm the files were created:

ls -lrth /tmp/jay_2018-02-05-21-02-274468596_readytouse.csv /tmp/cleaned_meta-54525d8da8a54e9d9005a29c63f2918b.json
-rw-rw-r-- 1 jay jay 143K Feb  5 21:23 /tmp/jay_2018-02-05-21-02-274468596_readytouse.csv

Please note, if you use filenames and set the OUTPUT_DIR environment variable, the environment variable takes priority (even if you specify /path/to/some/dir/uniquename.csv). The dataset and metadata files will be stored in the OUTPUT_DIR directory:

echo $OUTPUT_DIR
/opt/jay/

./build-new-dataset.py jay_$(date +"%Y-%m-%d-%H-%m-%N")_full.csv jay_$(date +"%Y-%m-%d-%H-%m-%N")_readytouse.csv

Prototyping with a List of Records

I use this script to convert a configurable number of records from the bottom of a csv file which helps build these type of prediction json files:

https://github.com/jay-johnson/antinex-core/blob/master/antinex_core/scripts/convert_bottom_rows_to_json.py

Verify the Celery Worker Processes a Task without Django¶

I find the first time I integrate Celery + Django + Redis can be painful. So I try to validate Celery tasks work before connecting Celery to Django over a message broker (like Redis). Here is a test tool for helping debug this integration with the celery-loaders project. It’s also nice not having to click through the browser to debug a new task.

Run the task test script

./run-celery-task.py -t drf_network_pipeline.users.tasks.task_get_user -f tests/celery/task_get_user.json
2018-06-05 22:41:39,426 - run-celery-task - INFO - start - run-celery-task
2018-06-05 22:41:39,426 - run-celery-task - INFO - connecting Celery=run-celery-task broker=redis://localhost:6379/9 backend=redis://localhost:6379/10 tasks=['drf_network_pipeline.users.tasks']

2018-06-05 22:41:39,549 - run-celery-task - INFO - end - run-celery-task

Verify the Celery Worker Processed the Task

If Redis and Celery are working as expected, the logs should print something similar to the following:

2018-06-06 05:41:39,535 - celery.worker.strategy - INFO - Received task: drf_network_pipeline.users.tasks.task_get_user[4931e1fc-3610-4259-8ccd-5724a1c50c79]

Additional Legacy Client API Tools¶

These tools and examples were created before the AntiNex Python Client was released. Please use that for official API examples.

Get a Prepared Dataset¶

export PREPARE_JOB_ID=1
./get-a-prepared-dataset.py

Get an ML Job¶

Any trained Keras Deep Neural Network models are saved as an ML Job.

export JOB_ID=1
./get-a-job.py

Get an ML Job Result¶

export JOB_RESULT_ID=1
./get-a-result.py

Get Recent Prepared Datasets¶

./get-recent-datasets.py

Get Recent ML Jobs¶

./get-recent-jobs.py

Get Recent ML Job Results¶

This is nice for reviewing historical accuracy as your tune your models.

./get-recent-results.py

Run Tests¶

The unit tests can be run:

./run-tests.sh

...

PASSED - unit tests

Or run a single test

source envs/dev.env; cd webapp; source ~/.venvs/venvdrfpipeline/bin/activate
python manage.py test drf_network_pipeline.tests.test_ml.MLJobTest

Multi-Tenant Simulations¶

Simulations run from the ./tests/ directory.

cd tests

Run the default user1 simulation in a new terminal:

./run-user-sim.py

In a new terminal start user2 simulation:

./run-user-sim.py user2

In a new terminal start user3 simulation:

./run-user-sim.py user3

Want to check how many threads each process is using?¶

It appears that either Keras or Tensorflow are using quite a bit of threads behind the scenes. On Ubuntu you can view the number of threads used by gunicorn or uwsgi with these commands:

ps -o nlwp $(ps awuwx | grep django | grep -v grep | awk '{print $2}')

If you’re running uwsgi instead of the gunicorn use:

ps -o nlwp $(ps awuwx | grep uwsgi | grep -v grep | awk '{print $2}')

Stop Full Stack¶

If you are running the “full stack”, then you can run this command to stop the docker containers:

./stop-stack.sh

Testing¶

Set up the Testing Runtime and Environment Variables

source ~/.venvs/venvdrfpipeline/bin/activate
source ./envs/dev.env

Change to the webapp directory

Tests need to run in the same directory as the manage.py
```
cd webapp
```
Run all Tests
```
python manage.py test
```

Run all Test Cases in a Test module

python manage.py test drf_network_pipeline.tests.test_ml

Run a Single Test Case

python manage.py test drf_network_pipeline.tests.test_ml.MLJobTest.test_ml_predict_helper_works

or

python manage.py test drf_network_pipeline.tests.test_user.AccountsTest.test_create_user_with_invalid_email

Linting¶

flake8 .

pycodestyle –exclude=.tox,.eggs,migrations
