Redis is an in-memory key-value store that requires proper security configuration. Install Redis from Ubuntu repositories, configure systemd supervision, bind to localhost only (127.0.0.1 ::1), set a strong password with requirepass, and rename or disable dangerous commands like FLUSHALL, CONFIG, and SHUTDOWN. Test connectivity with redis-cli ping and verify authentication works. Configure persistence with RDB snapshots or AOF logging based on durability needs. Never expose Redis port 6379 to the internet; use SSH tunnels or VPNs for remote access.
