Explore the concept of service identity as the foundation for Zero Trust security in a service mesh environment through this conference talk. Delve into the principles of service identity, including SPIFFE, and examine how various mesh technologies implement these concepts to provide seamless mTLS between workloads. Gain insights into the architecture of service mesh technologies and their role in identity-based security. Learn how Platform and Security teams can leverage service identity within and beyond the mesh, and understand its potential interoperability with enterprise PKI infrastructure. Cover topics such as traditional network security, cloud network security, mutual TLS, and Open Service Mesh. Benefit from the expertise of Matthew Bates and Joshua Van Leeuwen from Jetstack as they guide you through this critical aspect of modern cloud-native security.
