autovul 1.0.2

minimum code implementation for our USENIX paper `On the Security Risks of AutoML`.

This project is a minimized runnable project cut from trojanzoo, which contains more datasets, models, attacks and defenses. This repo will not be maintained.

This is a minimum code implementation of our USENIX'22 paper On the Security Risks of AutoML.

Abstract

The artifact discovers the vulnerability gap between manual models and automl models against various kinds of attacks (adversarial, poison, backdoor, extraction and membership) in image classification domain. It implements all datasets, models, and attacks used in our paper.
We expect the artifact could support the paper's claim that automl models are more vulnerable than manual models against various kinds of attacks, which could be explained by their small gradient variance.

Checklist

• Binary: on pypi with any platform.
• Model: Our pretrained models are available on Google Drive (link). Follow the model path style {model_dir}/image/{dataset}/{model}.pth to place them in correct location.
• Data set: CIFAR10, CIFAR100 and ImageNet32.
  Use --download flag to download them automatically at first running.
  ImageNet32 requires manual set-up at their website due to legality.
• Run-time environment:
  At any platform (Windows and Ubuntu tested).
  Pytorch and torchvision required. (CUDA 11.3 recommended)
  adversarial-robustness-toolbox required for extraction attack and membership attack.
• Hardware: GPU with CUDA support is recommended.
• Execution: Model training and backdoor attack would be time-consuming. It would cost more than half day on a Nvidia Quodro RTX6000.
• Metrics: Model accuracy, attack success rate, clean accuracy drop and cross entropy.
• Output: console output and saved model files (.pth).
• Experiments: OS scripts. Recommend to run scripts 3-5 times to reduce the randomness of experiments.
• How much disk space is required (approximately):
  less than 5GB.
• How much time is needed to prepare workflow (approximately): within 1 hour.
• How much time is needed to complete experiments (approximately): 3-4 days.
• Publicly available: on GitHub.
• Code licenses: GPL-3.
• Archived: GitHub commit ff315234561602203615d11166f8f346b4f29dd4.

Description

How to access

• GitHub
  pip install -e .
• PYPI
  pip install autovul
• Docker Hub
  docker pull local0state/autovul
• GitHub Packages
  docker pull ghcr.io/ain-soph/autovul

Hardware Dependencies

Recommend to use GPU with CUDA 11.3 and CUDNN 8.0.
Less than 5GB disk space is needed.

Software Dependencies

You need to install python==3.9, pytorch==1.10.x, torchvision==0.11.x manually.

ART (IBM) is required for extraction attack and membership attack.
pip install adversarial-robustness-toolbox

Data set

We use CIFAR10, CIFAR100 and ImageNet32 datasets.
Use --download flag to download them automatically at first running.
ImageNet32 requires manual set-up at their website due to legality.

Models

Our pretrained models are available on Google Drive (link). Follow the model path style {model_dir}/image/{dataset}/{model}.pth to place them in correct location.

Installation

• GitHub
• PYPI
  pip install autovul
• Docker Hub
• GitHub Packages

(optional) Config Path

You can set the config files to customize data storage location and many other default settings. View /configs_example as an example config setting.
We support 3 configs (priority ascend):

• package:
  (DO NOT MODIFY)
  autovul/base/configs/*.yml
autovul/vision/configs/*.yml
• user:
  ~/.autovul/configs/base/*.yml
~/.autovul/configs/vision/*.yml
• workspace:
  ./configs/base/*.yml
./configs/vision/*.yml

Experiment Workflow

Bash Files

Check the bash files under /bash to reproduce our paper results.

Train Models

You need to first run /bash/train.sh to get pretrained models.
If you run it for the first time, please run with --download flag to download the dataset:
bash ./bash/train.sh "--download"

It takes a relatively long time to train all models, here we provide our pretrained models on Google Drive (link). Follow the model path style {model_dir}/image/{dataset}/{model}.pth to place them in correct location.

Run Attacks

/bash/adv_attack.sh
/bash/poison.sh
/bash/backdoor.sh
/bash/extraction.sh
/bash/membership.sh

Run Other Exps

/bash/grad_var.sh
/bash/mitigation_backdoor.sh
/bash/mitigation_extraction.sh

For mitigation experiments, the architecture names in our paper map to:

• darts-i: diy_deep
• darts-ii: diy_no_skip
• darts-iii: diy_deep_noskip

These are the 3 options for --model_arch {arch} (with --model darts)

Evaluation and Expected Result

Our paper claims that automl models are more vulnerable than manual models against various kinds of attacks, which could be explained by low gradient variance.

Training

Most models around 96%-97% accuracy on CIFAR10.

Attack

For automl models on CIFAR10,

• adversarial
  higher success rate around 10% (±4%).
• poison
  lower accuracy drop around 5% (±2%).
• backdoor
  higher success rate around 2% (±1%) lower accuracy drop around 1% (±1%).
• extraction
  lower inference cross entropy around 0.3 (±0.1%).
• membership
  higher auc around 0.04 (±0.01%).

Others

• gradient variance
  automl with lower gradient variance (around 2.2).
• mitigation architecture
  deep architectures (darts-i, darts-iii) have larger cross entropy for extraction attack (around 0.5), and higher accuracy drop for poisoning attack (around 7%).
