Following our recent updates on Adversarial AI attack generation, the AIAS consortium is excited to continue informing the public about our work and unveil our cutting-edge research on Detection and Mitigation Techniques against adversarial AI threats.
Current State-of-the-Art (SotA): AI-based methods have proven highly effective in detecting traditional cyberattacks, with techniques such as Support Vector Machines, Deep Neural Networks, and other supervised learning models leading the way. However, AI-based detection systems themselves are vulnerable to adversarial AI attacks. While progress has been made, defense strategies are still in their early stages.
Key SotA Detection Approaches:
- MagNet Framework: Distinguishes adversarial samples by learning the normal sample manifold and detecting deviations.
- Generative Adversarial Networks (GANs): Used to detect adversarial AI attacks through sample analysis.
- Regression-Based Detectors: Combining linear regression and neural networks to identify adversarial samples.
- ART Tool: A comprehensive environment for testing AI models against adversarial attacks and employing defense modules.
Key SotA Mitigation Approaches:
- Data Modification Techniques: Adversarial training, gradient hiding, data compression, and transferability blocking.
- Model Modification Techniques: Regularization, defensive distillation, and feature squeezing.
- Auxiliary Tools: Defense-GAN, representation-guided denoisers, and platforms like CALDERA and Atomic Red Team, which emulate cyberattacks for system evaluation.
- Industry Frameworks: MITRE ATT&CK, CIS, and SCF offer guidelines for general cybersecurity, though they lack adversarial AI-specific classifications.
Beyond SotA: AIAS is advancing detection and mitigation strategies through innovative methodologies that surpass the current state of the art:
- Attack-Agnostic Detection Module:
- Capable of identifying both poisoning and evasion attacks.
- Powered by a life-long reinforcement learning model continuously trained with high-quality data from AIAS’s adversarial AI engine and deception components (e.g., digital twins, high-interaction honeypots).
- Advanced feature selection techniques, such as PCA, Mutual Information, and Chi-Square, will optimize data pre-processing.
- GAN-based mimic models will be developed to replicate system behavior and enhance the detection process.
- Two-Stage Mitigation Model:
- Precursor Step: Tailor-made algorithms will recommend a suite of mitigation techniques (e.g., defensive distillation, feature squeezing, model generalization improvement) suitable for defending against adversarial AI attacks.
- Successor Step: The effectiveness of each technique will be evaluated, with XAI methods (e.g., SHAP) providing transparent explanations for the proposed security actions.
- User-centric design ensuring efficiency, security, privacy, flexibility, and accountability – all while being transparent and understandable for security managers.
A Unified Platform: Unlike existing platforms, AIAS will integrate detection, mitigation, and explainability into a cohesive solution, enabling organizations to:
- Detect adversarial AI attacks proactively.
- Receive tailored mitigation strategies.
- Understand the rationale behind each security recommendation.
- Strengthen AI system resilience while preserving user privacy and maintaining ease of use.
As the AIAS project continues to push the boundaries of AI security research, we remain committed to empowering organizations with cutting-edge solutions to defend their AI-powered ecosystems.
Stay updated as we advance towards securing the future of AI systems!
