What this skill does
Uses nmap to detect open ports on a target host and collect service version and operating system information. Performs staged scanning from a fast top-port scan through detailed service version detection and OS fingerprinting, saving results in structured formats.
Important: This skill must only be used on systems where explicit written authorization has been obtained. Unauthorized port scanning is illegal in most jurisdictions and violates terms of service.
When to use
- Building a service inventory within a penetration testing scope
- Detecting unnecessarily exposed services
- Verifying service versions to map CVEs
- Periodically auditing network defense posture
