Google Cloud IAM (Identity and Access Management)
Unified access control and security for Google Cloud resources
What is IAM?
Google Cloud Identity and Access Management (IAM) is a comprehensive system that enables organizations to manage access to Google Cloud resources securely and efficiently. IAM provides fine-grained control over who (users) can take what action (roles and permissions) on which resources, ensuring that only authorized individuals and services have the necessary access.
By unifying access control across all Google Cloud services, IAM simplifies security administration, supports compliance requirements, and reduces the risk of unauthorized access. IAM is foundational for implementing the principle of least privilege, enabling organizations to grant the minimum permissions required for users and services to perform their tasks.
Architecture
Key Components
Identities
Users, groups, and service accounts that request access to Google Cloud resources. Identities can be managed within Google Cloud or federated from external identity providers.
Roles
A collection of permissions that define what actions an identity can perform. Roles can be basic (Owner, Editor, Viewer), predefined, or custom to meet specific needs.
Policies
IAM policies bind identities to roles at various resource levels (project, folder, organization), controlling access to Google Cloud resources.
Key Capabilities
Fine-Grained Access Control
Grant permissions at the resource, project, folder, or organization level for precise access management.
Unified Security Model
Centralizes access control across all Google Cloud services, simplifying security and compliance management.
Custom Roles & Automation
Create custom roles and automate policy management to fit unique organizational requirements.
