SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill identifies and assesses risks associated with internet-facing services, open ports, and firewall rule gaps, helping to prevent unauthorized access and lateral movement.

Core Features & Use Cases

  • Port and Service Risk Assessment: Classifies the risk level of open ports and running services.
  • Firewall Rule Analysis: Evaluates firewall rules for weaknesses and misconfigurations.
  • Segmentation Review: Assesses network segmentation against best practices.
  • Use Case: A security architect can use this skill to scan their cloud environment's security groups and on-premise firewall rules to identify any accidentally exposed database ports or overly permissive access rules.

Quick Start

Run the network exposure tool to analyze your network configuration and output the findings in JSON format.

FAQPage Schema
How do I assess firewall rule gaps and identify network segmentation weaknesses?

To assess firewall rule gaps and segmentation weaknesses, analyze network scan data, firewall rule exports, and topology information to enumerate internet-facing services and open ports. This process identifies potential lateral movement enablers and misconfigurations in your security posture.

What is network exposure scoring and when do I need it for cloud security configuration reviews?

Network exposure scoring classifies the risk level of open ports and running services to evaluate infrastructure security posture. You need it during cloud security configuration reviews to detect accidentally exposed database ports or overly permissive access rules.

How do I analyze open ports and internet-facing services for potential lateral movement risks?

Analyzing open ports and internet-facing services requires enumerating running services and evaluating firewall rules for weaknesses. By mapping these against network topology information, you identify segmentation weaknesses that could enable unauthorized lateral movement.

Can I use network exposure analysis for both on-premise firewall rules and cloud security groups?

Yes, network exposure analysis applies to both on-premise and cloud environments. A security architect can scan cloud security groups and on-premise firewall rules simultaneously to identify exposed database ports and overly permissive access rules across the infrastructure.

What data inputs do I need to perform a comprehensive network exposure risk assessment?

Comprehensive network exposure risk assessment requires network scan data, firewall rule exports, and network topology information. These inputs allow the tool to enumerate internet-facing services, identify open ports, and detect segmentation weaknesses accurately.

What is the best way to identify accidentally exposed database ports in my infrastructure?

The best way to identify exposed database ports is to run an automated network exposure analysis against your security groups and firewall rules. This evaluates open ports and running services, classifying risk levels and flagging overly permissive access rules.
