How do you secure a production Redis deployment?

Q: How do you secure a production Redis deployment?

Bind to localhost or private interface (bind 127.0.0.1) Enable requirepass / ACLs (Redis 6+) with fine-grained command/key permissions Use TLS (tls-port, tls-cert-file) for in-transit encryption Disable dangerous commands: rename-command FLUSHALL "", rename-command CONFIG "" Run Redis in a dedicated network namespace / VPC subnet Enable protected-mode yes
