SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill provides a comprehensive read-only audit framework for Google Cloud Platform VPC networks, enabling teams to assess architecture, firewall posture, NAT egress, and cross-project connectivity to enforce security and operability.

Core Features & Use Cases

  • VPC design evaluation for auto-mode vs custom-mode networks, subnets, Private Google Access, and VPC Flow Logs presence
  • Security posture assessment of firewall rules, hierarchical policies, and Shared VPC configurations
  • Connectivity and routing checks for Cloud Interconnect, Cloud VPN, and Cloud Router across regions and projects
  • Reporting and optimization guidance with findings, recommended mitigations, and governance artifacts

Quick Start

Run the read-only audit to generate a baseline GCP VPC network security report.

FAQPage Schema
How do I audit my GCP VPC network and firewall posture?▼

To audit your GCP VPC network, this skill runs read-only gcloud commands to document firewall rules, NAT egress, and interconnect topology, producing a structured report with findings and recommendations for governance.

What does a GCP VPC network security audit include?▼

A GCP VPC network security audit includes evaluating auto-mode vs custom-mode networks, assessing hierarchical firewall policies, checking Private Google Access, and verifying VPC Flow Logs presence.

Can I assess Shared VPC and cross-project connectivity configurations?▼

Yes, you can assess Shared VPC configurations and cross-project connectivity. The audit examines Cloud Interconnect, Cloud VPN, and Cloud Router setups across regions and projects to ensure operability.

How do I check if my GCP firewall rules are compliant?▼

You can check GCP firewall rule compliance by running this read-only audit. It evaluates security posture, identifies risks, and generates compliance-ready artifacts based on your current configurations.

Does the GCP network audit require write access to my project?▼

No, the GCP network audit does not require write access. It operates using strictly read-only gcloud commands to safely assess your architecture and generate a baseline report without modifying resources.

What is the best way to evaluate GCP Cloud Interconnect and NAT egress topology?▼

The best way to evaluate GCP Cloud Interconnect and NAT egress topology is using a structured audit skill that maps connectivity routing and documents configurations against a production-ready baseline.
