Exam Domains
The exam covers five critical security domains. Mastering each is essential for certification success.
| Domain | Key Focus |
|---|---|
| Configuring Access | IAM, service accounts, resource hierarchy |
| Managing Operations | Security monitoring, incident response |
| Configuring Network Security | VPC, firewalls, perimeter controls |
| Ensuring Compliance | Regulatory requirements, auditing |
| Managing Data Protection | Encryption, DLP, key management |
Domain 1: Configuring Access (Critical - IAM Focus)
Identity and Access Management is the heart of GCP security. You must master:
- Resource Hierarchy: Organization → Folder → Project → Resource policy inheritance
- IAM Roles: Predefined vs custom roles, least privilege principle
- Service Accounts: Types, key management, workload identity
- IAM Conditions: Time-based and attribute-based access control
- IAM Deny Policies: Explicit deny rules
- Workload Identity Federation: Keyless authentication for external workloads
- Organization Policies: Constraints and governance
Domain 2: Managing Operations
- Security Command Center (SCC) for threat detection
- Cloud Audit Logs configuration and analysis
- Incident response procedures
- Security monitoring and alerting
- Vulnerability scanning and management
- Chronicle SIEM integration
Domain 3: Configuring Network Security
VPC and network security is heavily tested:
- VPC Firewalls: Hierarchical rules, firewall policies
- VPC Service Controls: Prevent data exfiltration
- Private Google Access: Secure access to Google APIs
- Shared VPC: Centralized network management
- VPC Peering: Secure inter-VPC communication
- Cloud Armor: DDoS protection and WAF
- Identity-Aware Proxy (IAP): Zero-trust access
- Hybrid Connectivity: Securing VPN and Interconnect
Domain 4: Ensuring Compliance
- Compliance frameworks (HIPAA, PCI-DSS, SOC 2, ISO 27001)
- Assured Workloads for regulated industries
- Access Transparency and Access Approval
- Audit logging and retention
- Policy enforcement with Organization Policies
Domain 5: Managing Data Protection
- Cloud KMS: Key management and rotation
- Cloud HSM: Hardware security modules
- CMEK: Customer-managed encryption keys
- DLP API: Sensitive data discovery and masking
- Secret Manager: Secure secrets storage
- Encryption at rest and in transit
- Data classification and labeling
Key Security Services to Master
Identity & Access
- Cloud IAM: Identity and access management
- Cloud Identity: User and device management
- BeyondCorp Enterprise: Zero-trust access
- Identity-Aware Proxy: Context-aware access
- Workload Identity Federation: External identity
Security Operations
- Security Command Center: Unified security view
- Chronicle: SIEM and threat intelligence
- Cloud Armor: WAF and DDoS protection
- Binary Authorization: Container security

Study Strategy
- Master IAM deeply: This is the foundation of everything
- Understand VPC Service Controls: Critical for data protection
- Practice with Security Command Center: Hands-on experience essential
- Know compliance frameworks: HIPAA, PCI-DSS requirements
- Study network security: Firewalls, private connectivity
Important: Many questions are scenario-based. Focus on understanding when to use each security service, not just what they do.
