What problem does it solve?

Insecure VPS setups expose services and ports to the internet; this Skill guides you to deploy and configure a focused UFW firewall to restrict unwanted access.

Core Features & Use Cases

  • Install and enable the UFW firewall on Ubuntu/Debian systems
  • Set secure default policies (deny incoming, allow outgoing)
  • Open necessary ports for services (SSH, web, database as required)
  • Create and manage application-specific rules
  • Verify firewall status and support IPv4/IPv6 traffic
  • Use during initial hardening, ongoing security maintenance, and audits

Quick Start

Install and configure the UFW firewall on your Ubuntu/Debian VPS with a secure default-deny posture.
