SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires google-cloud-securitycenter, google-cloud-asset, google-cloud-storage, google-cloud-compute, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a structured framework to audit Google Cloud Platform environments for IAM policy compliance, firewall exposure, and storage permissions using Forseti Security, Security Command Center, and the gcloud CLI.

Core Features & Use Cases

  • IAM policy auditing across organizations and projects to identify overly permissive bindings.
  • Network and firewall assessment to detect exposed ingress rules and misconfigurations.
  • Storage permissions and encryption checks to ensure buckets are not publicly accessible and use proper CMEK/uniform access.
  • Compliance alignment with CIS GCP Foundations and ongoing monitoring for multi-project environments.

Quick Start

Run the agent against your GCP organization to produce a security assessment report.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit GCP IAM permissions across multiple projects?

You can audit GCP IAM permissions across organizations and multiple projects by running assessment scripts with Forseti Security and gcloud CLI to identify overly permissive bindings and evaluate baseline compliance.

What is the best way to check GCP firewall rules for exposed ingress?

Checking GCP firewall rules for exposed ingress involves performing network and firewall assessments using Forseti Security and gcloud CLI to detect misconfigurations and evaluate network exposure across your environment.

How do I verify GCP storage bucket encryption and public access settings?

Verifying GCP storage bucket encryption involves running storage permission and encryption checks to ensure buckets are not publicly accessible and properly enforce CMEK or uniform access controls.

Do I need a GCP organization context to run a Forseti security assessment?

Yes, running a Forseti security assessment requires a GCP organization context, sufficient IAM permissions, and the gcloud CLI installed to execute the assessment scripts across your projects.

Can I align GCP security audits with CIS benchmarks using Security Command Center?

Yes, you can align GCP security audits with CIS GCP Foundations benchmarks by using Security Command Center and Forseti to assess IAM policies, network exposure, and storage encryption for ongoing compliance monitoring.

What are the limitations of using Forseti for GCP security assessments?

Forseti GCP security assessments are limited by the requirement of a GCP organization context and sufficient IAM permissions, meaning individual project-level accounts without organizational access cannot execute the full multi-project evaluation.
