List of some best practices to harden Redis for DevSecOps

Disable the CONFIG command

redis-cli config set config-command " "

Disable the FLUSHDB and FLUSHALL commands

redis-cli config set stop-writes-on-bgsave-error yes

Enable authentication

Set a password in the Redis configuration file (redis.conf) using the requirepass directive. Restart Redis service to apply changes.

Bind Redis to a specific IP address

Edit the bind directive in the Redis configuration file to specify a specific IP address.

Enable SSL/TLS encryption

Edit the redis.conf file to specify SSL/TLS options and certificate files. Restart Redis service to apply changes.

Disable unused Redis modules

Edit the redis.conf file to disable modules that are not needed. Use the module-load and module-unload directives to control modules.

Set limits for memory and connections

Edit the maxmemory and maxclients directives in the redis.conf file to set limits for Redis memory and connections.

Monitor Redis logs

Regularly check Redis logs for suspicious activities and errors. Use a log analyzer tool to help detect anomalies.

Regularly update Redis

Keep Redis up-to-date with the latest security patches and updates. Monitor vendor security advisories for any vulnerabilities that may affect Redis.
