Explore data security and storage hardening techniques in Rook and Ceph in this 18-minute conference talk from KubeCon + CloudNativeCon Europe 2022. Delve into the security model exposed by Rook with Ceph, the leading open-source software-defined storage platform. Examine various hardening options suitable for different threat profiles, including threat modeling, implementing separate security zones to limit attack blast radius, encryption at rest and in-flight using FIPS 140-2 validated ciphers, hardened builds and default configurations, user access controls, and key management. Learn about data retention, secure deletion, and the additional security benefits provided by containerization. Discover how Rook simplifies the application of hardening options through simple .yaml file modifications. Cover topics such as network security zones, encryption and key management, control plane security, identity and access management, auditing, and infrastructure hardening.
