AI Model Security Defense System: Combating Adversarial Attacks and Generative AI Cyber Threats

Secure-AI-Model-Defense-System is an open-source project focused on detecting adversarial attacks, enhancing AI model robustness, and preventing prompt exploitation in generative AI. It integrates AI and cybersecurity technologies to address the new challenge of AI systems becoming targets of attacks.

With the widespread application of AI technology, AI systems have become important targets of cyberattacks. Adversarial attacks deceive models through tiny perturbations, while generative AI brings new threats such as prompt injection. This project develops a comprehensive defense solution targeting these challenges, integrating AI and cybersecurity, which has practical significance.

Adversarial attacks cause models to output errors through tiny perturbations, threatening various AI applications. The project studies classic attack mechanisms such as FGSM, PGD, and C&W, establishes attack detection capabilities, and uses defense methods like adversarial training, input preprocessing, and feature compression to enhance model robustness.

Generative AI faces threats such as prompt injection and model jailbreaking. The project develops mechanisms like semantic structure analysis, injection pattern recognition, and interception/purification to balance convenience and security, protecting AI applications in production environments.

The system adopts a modular architecture. Its core modules include a threat detection engine, risk assessment module, response decision system, and log audit component. It can be flexibly configured as an independent gateway or integrated into existing AI services. Using modern machine learning frameworks, the code is clear and the documentation is comprehensive.

The system has millisecond-level real-time threat detection and response capabilities, emphasizing instant attack disposal. It implements a monitoring and alert mechanism to help operations teams understand the security status; log auditing supports post-incident traceability and continuous model improvement.

It is suitable for scenarios such as image recognition and content moderation, providing additional protection in high-security demand fields like financial risk control and medical diagnosis. Enterprise-level deployment can integrate with existing security infrastructure to form a deep defense system.

The project is open-source, and community contributions are welcome. In the future, it will support more AI models, enhance defense against new types of attacks, and improve usability. It provides a learning and practice reference for AI security developers and researchers.
