Building enterprise-ready AI requires ensuring users can only augment prompts with data they're authorized to access. Relationship-based access control (ReBAC) is particularly well-suited for fine-grained authorization in Retrieval-Augmented Generation (RAG) because it makes decisions based on relationships between objects, offering more precise control compared to traditional models like RBAC and ABAC.
This talk covers how ReBAC systems can safeguard sensitive data in RAG pipelines. We'll start with why Authorization is critical for RAG pipelines, and how Google Zanzibar achieves this with ReBAC. We'll then illustrate how pre-filtering vector database queries with a list of authorized object IDs can improve efficiency & security. The talk will also include a demo implementing fine-grained authorization for RAG using Pinecone, Langchain, OpenAI, and SpiceDB.

![Are We Ready For The Next Cyber Security Crisis Like Log4Shell? - Soroosh Khodami
#VoxxedDaysCERN26
AI era is bright, but full of terrors!
In a world where vulnerabilities like Log4Shell, Spring4Shell, and the XZ Backdoor make headlines, securing our software ecosystem has never been more critical. In this session, Soroosh, a hands-on architect with experience working on security platform services for large enterprises like Rabobank, will share practical strategies and best practices for securing the software development process, applicable to both small startups and large organizations.
Key takeaways and questions that will be answered in this session:
[Live Demo] What is a Supply Chain Attack, and how dangerous can it be?
An example of lateral movement that begins with a basic SQL injection attack and escalates to gaining root access to a Kubernetes cluster
Exploring new attack vectors in the AI era and the defense strategies to detect, prevent and mitigate them
Most effective practices to secure your CI/CD process
Practical strategies on how Software Bill of Materials (SBOM) help us prepare for the next Log4Shell crisis?
