Firewall Configuration Skill

Configure UFW firewall to control network traffic and minimize attack surface on VPS servers.

What This Skill Does

This skill helps AI agents configure UFW (Uncomplicated Firewall) on Ubuntu/Debian servers. Without a firewall, every port is potentially accessible to the internet. A properly configured firewall creates a security perimeter that only allows necessary traffic.

Key capabilities:

• Install and enable UFW firewall
• Set secure default policies (deny incoming, allow outgoing)
• Open specific ports for required services
• Configure application-specific rules
• Manage firewall rules and verify configuration
• Handle IPv4 and IPv6 traffic
