How to Set up a Firewall for Redis using ufw

[Dave Johnson]

In this tutorial, I explain how to set up a firewall for a Redis server running on a Raspberry Pi using ufw, which simplifies the process of managing firewall rules on Debian-based systems. The guide covers installing ufw, configuring default rules to deny incoming traffic while allowing outgoing traffic, and specifically allowing connections for SSH, HTTP, Samba, and Redis. By creating application profiles and testing the firewall with tools like nmap, users can ensure their Redis server is securely accessible only to designated IP addresses, enhancing security against potential password attacks.
