Title: AWS re:Inforce 2024 - Enhance AppSec: Generative AI integration in AWS testing (APS301)

Insights:

• Generative AI in Security Testing: Generative AI is revolutionizing application security by introducing new security challenges and opportunities for enhanced security testing.
• Three-Tiered Security Model: AWS employs a three-tiered model for generative AI security testing, focusing on infrastructure, tools, and application layers.
  • Infrastructure Layer: Emphasizes data protection, container runtime security, and strict access control.
  • Tools Layer: Focuses on code vulnerabilities, malicious tool manipulation, and application logic testing.
  • Application Layer: Concerns data leakage, model exploitation, and prompt-based testing.
• Threat Modeling: AWS uses threat modeling as a mental exercise to identify potential threats and compensating controls, forming the basis for penetration testing.
• Container Security: Ensuring container runtime security and proper isolation to protect customer data and prevent unauthorized access.
• Model Formats: SafeTensors is recommended over Pickle and H5 formats due to its memory safety and lack of code serialization.
• Agentic Behavior: Introducing agency in models allows them to interact with the outside world, but it also introduces new security risks such as indirect prompt injections.
• Universal and Transferable Attacks (UNT): These attacks can bypass model guardrails and are transferable across different models due to similar training data.
• Guardrails and Filters: Implementing guardrails and topical filters can help mitigate the impact of prompt injections and other malicious activities.
• Emerging Threat Landscape: The threat landscape for generative AI is rapidly evolving, necessitating continuous updates to security practices and threat models.

Quotes:

• "Generative AI is transforming the application security space."
• "At AWS, security is everyone's priority. It is our number one priority."
• "We have developed a framework that is largely guided by OWASP's LLM top 10."
• "Large language models are statistical. They're mathematical models."
• "Universal and transferable attacks were discovered to be universal and they were discovered to be transferable to other models that they'd never been tested on before with high degrees of accuracy."
• "The barrier of entry is rather low. Like I said, 1,000, maybe 5,000 queries on the upper limit. With a good algorithm, you can discover one of these."
• "You need to be agile and prioritize what is important for your mission and how to protect that mission."
