Learn how to implement SPIFFE workload identity beyond initial setup in this 26-minute conference talk from fwd:cloudsec. Discover practical strategies for replacing legacy authentication mechanisms like long-lived shared secrets with cryptographic workload identities in existing infrastructure. Explore authentication and authorization options using SPIFFE, examine real-world examples of implementing SPIFFE-based authentication between legacy services and cloud APIs, and understand organizational rollout strategies based on experience with large-scale deployments. Gain insights into moving from basic SPIFFE and SPIRE implementation to production-ready workload identity systems that enhance security and scalability in constantly evolving architectures.
