How to Secure Redis: IP Binding, Strong Passwords, and Command Renaming
This guide explains how to secure Redis by configuring trusted IP bindings, enabling strong password authentication, and renaming or disabling dangerous commands, while also emphasizing the need for external safeguards such as firewalls and avoiding default ports.
Redis was designed with simplicity in mind, so it lacks complex built-in security settings.
Therefore, Redis must be deployed in a secure environment, e.g., avoid the default port, use firewalls, and perform security checks in web applications that access Redis.
1. Trusted IP binding
Specify which IP addresses may connect to Redis to block external access.
Configuration: edit bind 192.168.1.100 10.0.0.1 in redis.conf (remove the leading “#”).
2. Authentication
Require a password for client connections. Use a strong password (32 + characters) because Redis can handle up to 150 000 password attempts per second.
Configuration: set requirepass your_password in redis.conf (uncomment the line).
3. Command renaming
Rename or disable dangerous commands so that only trusted personnel know the new names.
Example: rename CONFIG to a random string: rename-command CONFIG b840fc02 To completely disable a command, rename it to an empty string: rename-command CONFIG "" Note: In a master‑slave setup, renamed commands are sent to slaves; if the slave does not have the same renaming, errors will occur.
