Day 2: Security and Backup
Section titled “Day 2: Security and Backup”Module 4: Security Configuration
- TLS for transport and HTTP layers
- Native realm, LDAP, SAML, and OIDC authentication
- Role-based access control (RBAC)
- Field-level and document-level security
- Hands-on: Configure TLS, RBAC, and audit logging
Module 5: Backup and Disaster Recovery
- Snapshot repositories — S3, GCS, Azure, NFS
- Snapshot policies and SLM
- Restore operations and partial restores
- Cross-cluster replication (CCR)
- Hands-on: Set up automated snapshots and test restore
Module 6: Upgrades and Maintenance
