SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides quick access to information about network ports and their associated protocols, crucial for understanding network services during security assessments.

Core Features & Use Cases

  • Port Identification: Quickly find the protocol and service associated with common TCP/UDP ports.
  • Service Enumeration Guidance: Offers command examples for enumerating services on discovered ports.
  • Attack Surface Mapping: Helps identify potential vulnerabilities by understanding running services.
  • Use Case: When investigating an unknown server, you can ask the assistant about port 80 to understand it's likely running HTTP and what further steps you might take.

Quick Start

Provide a reference for common network port numbers and their associated services.
