AWS → GCP: Key Differences

  • Security Command Center ≈ AWS Security Hub + GuardDuty.

  • Premium tier adds: Event Threat Detection (similar to GuardDuty), Container Threat Detection.

  • Built-in integration with all GCP services — no agents to deploy for most findings.

📌

Key Concepts to Know

  • 1

    Security Health Analytics: scans GCP configuration for misconfigurations (open firewall rules, public buckets).

  • 2

    Event Threat Detection: detects threats in Cloud Logging — cryptomining, data exfiltration, brute force.

  • 3

    Web Security Scanner: scans App Engine, Compute Engine, GKE for web vulnerabilities.

  • 4

    Findings: security issues surfaced with severity, asset, and remediation guidance.

💡

DCE Interview Tips

  • 'Security Command Center gives your security team a single dashboard showing all misconfigurations, vulnerabilities, and active threats across your entire GCP environment.'

  • 'Instead of checking each service manually, SCC automatically flags if a Cloud Storage bucket is public or if someone is mining crypto in your environment.'

⚠️

Common Gotchas

  • !

    Standard tier is free but has limited findings. Premium tier has the most value but costs significantly more.

  • !

    SCC is Organization-level — requires an Organization resource hierarchy.
