Google Cloud Platform

Google Cloud Platform (GCP) provides a comprehensive suite of cloud computing services built on Google's global infrastructure. Organizations leverage GCP for scalable compute resources, managed services, advanced data analytics, and machine learning capabilities while benefiting from Google's security expertise and infrastructure investments.

Security Architecture

GCP implements security through multiple layers, starting with physical security of data centers and extending through infrastructure security, service deployment, and data protection. The shared responsibility model defines clear boundaries between Google's security obligations and customer responsibilities for securing their applications and data.

Identity and Access Management (IAM) in GCP provides fine-grained access control through roles and permissions, enabling organizations to implement least-privilege access principles. Service accounts facilitate secure authentication between GCP services while organizational policies enforce security requirements across projects and resources.

Network Security

Virtual Private Cloud (VPC) networks provide isolated network environments with customizable IP addressing, subnetting, and routing. Cloud Firewall rules control traffic flow between resources, while Cloud Armor protects applications from DDoS attacks and web-based threats at the edge of Google's network.

Private Google Access enables resources without external IP addresses to access Google services securely, reducing exposure to internet-based threats. VPC Service Controls create security perimeters around GCP resources, preventing data exfiltration and unauthorized access to sensitive services.

Data Protection

GCP encrypts data at rest by default using AES-256 encryption, with options for customer-managed encryption keys (CMEK) when organizations require direct control over key material. Data in transit is protected through TLS encryption, with automatic encryption between Google data centers using Application Layer Transport Security (ALTS).

Cloud Key Management Service (KMS) provides centralized key management for encryption keys used across GCP services. Integration with Cloud HSM offers FIPS 140-2 Level 3 validated hardware security modules for organizations with stringent key protection requirements.
