SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill helps security teams assess network infrastructure resilience by performing comprehensive scanning and enumeration of IP networks, DNS configurations, MITM risks, VLAN hopping, IPv6 behaviors, SMB/NetBIOS exposure, sniffing, and DoS vulnerability assessment.

Core Features & Use Cases

  • Comprehensive infrastructure assessment: port scanning, DNS assessment, MITM risk analysis, VLAN hopping checks, IPv6 evaluations, SMB/NetBIOS exposure, sniffing, and DoS testing in authorized scopes.
  • Reference-guided learning: includes structured reference materials to guide safe, repeatable testing and documentation of findings for audits or CTF-like exercises.
  • Real-world scenario: evaluate a corporate network segment to identify exposed services, misconfigurations, and defensible actions with evidence trails.

Quick Start

Run a full IP infrastructure assessment on your target network to identify open ports, services, and misconfigurations.

FAQPage Schema
What does a comprehensive network infrastructure assessment include?

A network infrastructure assessment includes port scanning, DNS analysis, MITM risk checks, VLAN hopping, IPv6 handling, SMB/NetBIOS exposure, sniffing, and DoS readiness testing in authorized scopes.

How do I test my network for VLAN hopping and MITM risks?

To test for VLAN hopping and MITM risks, run a guided infrastructure assessment that applies controlled scanning and analysis techniques to identify misconfigurations and defensive gaps with logged evidence.

Can I use this to evaluate SMB and NetBIOS exposure on a corporate network segment?

Yes, you can evaluate SMB and NetBIOS exposure on a corporate network segment by running the assessment to identify exposed services, misconfigurations, and defensible actions with comprehensive result logging.

What is the best way to document network pentest findings for audits?

The best way to document network pentest findings is using a repeatable, logged workflow that captures evidence trails during DNS analysis, port scanning, and vulnerability testing for audit compliance.

Does infrastructure testing work for IPv6 network evaluations?

Yes, infrastructure testing works for IPv6 network evaluations by assessing IPv6 behaviors alongside DNS configurations, sniffing, and DoS vulnerability checks within your authorized environment.

When should I avoid running active network vulnerability scans?

You should avoid running active network vulnerability scans in unauthorized environments, as infrastructure testing requires careful, policy-compliant execution to prevent DoS impacts or unauthorized access.
