content, and trimming would damage technical accuracy.\"\n---\n\n# Performing GCP Security Assessment with Forseti\n\n## When to Use\n\n- When conducting periodic security assessments of GCP organizations and projects\n- When onboarding new GCP projects and establishing security baselines\n- When compliance mandates CIS GCP Foundations Benchmark evaluation\n- When auditing IAM bindings, firewall rules, and storage ACLs across multiple GCP projects\n- When building continuous security monitoring for GCP infrastructure\n\n**Do not use** as a replacement for GCP Security Command Center Premium for real-time threat detection, for application-level vulnerability scanning (use Web Security Scanner), or for GKE-specific security (use GKE Security Posture).\n\n## Prerequisites\n\n- GCP Organization with Organization Admin or Security Admin IAM role\n- gcloud CLI authenticated with sufficient permissions (`roles\u002Fsecuritycenter.admin`, `roles\u002Fiam.securityReviewer`)\n- Security Command Center (SCC) enabled at the organization level\n- ScoutSuite installed for multi-cloud comparison (`pip install scoutsuite`)\n- Python 3.8+ for custom audit scripts using google-cloud-asset and google-cloud-securitycenter libraries\n\n## Workflow\n\n### Step 1: Enable Security Command Center and Asset Inventory\n\nEnable SCC and set up Cloud Asset Inventory for comprehensive resource visibility.\n\n```bash\n# Enable Security Command Center API\ngcloud services enable securitycenter.googleapis.com \\\n  --project=PROJECT_ID\n\n# Enable Cloud Asset API\ngcloud services enable cloudasset.googleapis.com \\\n  --project=PROJECT_ID\n\n# List all assets in the organization\ngcloud asset search-all-resources \\\n  --scope=organizations\u002FORG_ID \\\n  --asset-types=\"compute.googleapis.com\u002FInstance,storage.googleapis.com\u002FBucket,iam.googleapis.com\u002FServiceAccount\" \\\n  --format=\"table(name, assetType, location, project)\"\n\n# Export asset inventory to BigQuery for analysis\ngcloud asset export \\\n  --organization=ORG_ID \\\n  --output-bigquery-force \\\n  --output-bigquery-dataset=projects\u002FPROJECT_ID\u002Fdatasets\u002Fasset_inventory \\\n  --output-bigquery-table=resources \\\n  --content-type=resource\n```\n\n### Step 2: Audit IAM Policies and Bindings\n\nReview IAM policies across the organization for overly permissive bindings, primitive roles, and service account misuse.\n\n```bash\n# List all IAM policy bindings at org level\ngcloud organizations get-iam-policy ORG_ID \\\n  --format=json > org-iam-policy.json\n\n# Find all users with Owner or Editor roles across projects\ngcloud asset search-all-iam-policies \\\n  --scope=organizations\u002FORG_ID \\\n  --query=\"policy:roles\u002Fowner OR policy:roles\u002Feditor\" \\\n  --format=\"table(resource, policy.bindings.role, policy.bindings.members)\"\n\n# Identify service accounts with admin roles\ngcloud asset search-all-iam-policies \\\n  --scope=organizations\u002FORG_ID \\\n  --query=\"policy.bindings.members:serviceAccount AND policy:roles\u002Fowner\" \\\n  --format=json\n\n# Check for allUsers or allAuthenticatedUsers bindings (public access)\ngcloud asset search-all-iam-policies \\\n  --scope=organizations\u002FORG_ID \\\n  --query=\"policy:allUsers OR policy:allAuthenticatedUsers\" \\\n  --format=\"table(resource, policy.bindings.role, policy.bindings.members)\"\n\n# List service account keys older than 90 days\ngcloud iam service-accounts keys list \\\n  --iam-account=SA_EMAIL \\\n  --managed-by=user \\\n  --format=\"table(name,validAfterTime,validBeforeTime)\"\n```\n\n### Step 3: Assess Firewall Rules and Network Configuration\n\nAudit VPC firewall rules for overly permissive ingress rules, missing logging, and network exposure.\n\n```bash\n# List all firewall rules allowing ingress from 0.0.0.0\u002F0\ngcloud compute firewall-rules list \\\n  --filter=\"direction=INGRESS AND sourceRanges=0.0.0.0\u002F0\" \\\n  --format=\"table(name, network, allowed, sourceRanges, targetTags)\"\n\n# Find firewall rules allowing all protocols\u002Fports\ngcloud compute firewall-rules list \\\n  --filter=\"direction=INGRESS AND allowed[].IPProtocol=all\" \\\n  --format=\"table(name, network, sourceRanges, targetTags)\"\n\n# Check for SSH (22) and RDP (3389) open to internet\ngcloud compute firewall-rules list \\\n  --filter=\"direction=INGRESS AND sourceRanges=0.0.0.0\u002F0 AND (allowed[].ports=22 OR allowed[].ports=3389)\" \\\n  --format=\"table(name, network, allowed, sourceRanges)\"\n\n# Audit VPC flow log configuration\ngcloud compute networks subnets list \\\n  --format=\"table(name, region, enableFlowLogs, logConfig.aggregationInterval)\"\n```\n\n### Step 4: Audit Cloud Storage Bucket Permissions\n\nCheck for publicly accessible storage buckets and missing encryption configurations.\n\n```bash\n# List all buckets in a project\ngsutil ls -p PROJECT_ID\n\n# Check bucket IAM for public access\nfor bucket in $(gsutil ls -p PROJECT_ID); do\n  echo \"=== $bucket ===\"\n  gsutil iam get \"$bucket\" | grep -E \"allUsers|allAuthenticatedUsers\" && \\\n    echo \"  WARNING: PUBLIC ACCESS DETECTED\" || \\\n    echo \"  OK: No public access\"\ndone\n\n# Check bucket encryption configuration\nfor bucket in $(gsutil ls -p PROJECT_ID); do\n  echo \"=== $bucket ===\"\n  gsutil kms encryption \"$bucket\" 2>\u002Fdev\u002Fnull || echo \"  Using Google-managed encryption\"\ndone\n\n# Check uniform bucket-level access enforcement\nfor bucket in $(gsutil ls -p PROJECT_ID); do\n  gsutil uniformbucketlevelaccess get \"$bucket\"\ndone\n```\n\n### Step 5: Run ScoutSuite for Comprehensive Assessment\n\nExecute ScoutSuite for an automated multi-check security assessment of the GCP environment.\n\n```bash\n# Run ScoutSuite against GCP\npython3 -m ScoutSuite gcp \\\n  --user-account \\\n  --all-projects \\\n  --report-dir .\u002Fscoutsuite-gcp-report\n\n# Run with service account credentials\npython3 -m ScoutSuite gcp \\\n  --service-account

.\u002Fscoutsuite-gcp-report\u002Fgcp-report.html\n```\n\n### Step 6: Query Security Command Center Findings\n\nRetrieve and analyze SCC findings for vulnerabilities, misconfigurations, and threats.\n\n```bash\n# List active SCC findings\ngcloud scc findings list ORG_ID \\\n  --filter=\"state=\\\"ACTIVE\\\" AND severity=\\\"CRITICAL\\\"\" \\\n  --format=\"table(finding.category, finding.severity, finding.resourceName, finding.eventTime)\"\n\n# List findings by category\ngcloud scc findings list ORG_ID \\\n  --filter=\"state=\\\"ACTIVE\\\" AND category=\\\"PUBLIC_BUCKET_ACL\\\"\" \\\n  --format=json\n\n# Get finding statistics grouped by category\ngcloud scc findings group ORG_ID \\\n  --group-by=\"category\" \\\n  --filter=\"state=\\\"ACTIVE\\\"\"\n\n# List compliance violations from SCC\ngcloud scc findings list ORG_ID \\\n  --filter=\"state=\\\"ACTIVE\\\" AND sourceProperties.compliance_standard=\\\"CIS\\\"\" \\\n  --format=\"table(finding.category, finding.severity, finding.resourceName)\"\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|------------|\n| Security Command Center | GCP-native security and risk management platform that provides asset inventory, vulnerability detection, and threat monitoring |\n| Forseti Security | Open-source GCP security toolkit (now deprecated in favor of SCC) that provided inventory, scanning, enforcement, and notification capabilities |\n| Cloud Asset Inventory | GCP service that provides a complete inventory of cloud resources with metadata, IAM policies, and org policy configurations |\n| CIS GCP Foundations Benchmark | Security best practice guidelines from Center for Internet Security specific to Google Cloud Platform configuration |\n| Uniform Bucket-Level Access | GCP storage setting that disables legacy ACLs and enforces access exclusively through IAM policies for consistent access control |\n| Organization Policy | GCP constraint-based governance mechanism that restricts resource configurations across the organization hierarchy |\n\n## Tools & Systems\n\n- **Security Command Center**: GCP-native CSPM providing asset inventory, vulnerability findings, and compliance scoring\n- **ScoutSuite**: Multi-cloud security auditing tool with comprehensive GCP checks for IAM, compute, storage, and networking\n- **gcloud CLI**: Primary command-line interface for querying GCP resource configurations and security settings\n- **Cloud Asset Inventory**: API for searching and exporting resource metadata and IAM policies across GCP projects\n- **Forseti Security**: Legacy open-source GCP security toolkit, superseded by SCC but still referenced in compliance frameworks\n\n## Common Scenarios\n\n### Scenario: Assessing a Newly Acquired GCP Organization\n\n**Context**: After a company acquisition, the security team needs to assess the security posture of the acquired company's GCP organization with 30+ projects.\n\n**Approach**:\n1. Enable Cloud Asset API and export full resource inventory to BigQuery for analysis\n2. Run `gcloud asset search-all-iam-policies` to find all Owner\u002FEditor bindings and public access grants\n3. Audit firewall rules across all projects for overly permissive ingress from `0.0.0.0\u002F0`\n4. Check all storage buckets for public access using `gsutil iam get`\n5. Run ScoutSuite for a comprehensive automated assessment with HTML report\n6. Enable SCC and review all CRITICAL and HIGH findings\n7. Generate a risk-prioritized remediation roadmap for the integration team\n\n**Pitfalls**: GCP IAM bindings are inherited from organization to folder to project. A permissive binding at the organization level affects all downstream projects. Always audit IAM at every level of the hierarchy, not just at the project level.\n\n## Output Format\n\n```\nGCP Security Assessment Report\n=================================\nOrganization: acme-acquired-org (ORG_ID: 123456789)\nProjects Assessed: 34\nAssessment Date: 2026-02-23\nStandards: CIS GCP Foundations 2.0\n\nIAM FINDINGS:\n  Users with Owner role at org level:       3\n  Service accounts with Editor role:        12\n  Resources with allUsers binding:           5\n  Service account keys > 90 days:           18\n\nNETWORK FINDINGS:\n  Firewall rules allowing 0.0.0.0\u002F0:       14\n  SSH open to internet:                      7\n  RDP open to internet:                      2\n  Subnets without VPC flow logs:            22\n\nSTORAGE FINDINGS:\n  Publicly accessible buckets:               5\n  Buckets without CMEK encryption:          28\n  Buckets without uniform access:           15\n\nCRITICAL FINDINGS: 12\nHIGH FINDINGS: 34\nMEDIUM FINDINGS: 78\nLOW FINDINGS: 145\n\nTOP REMEDIATION PRIORITIES:\n  1.
