How do ensure compliance and governance across Azure environments

Azure Policy:

• Automated Guardrails: Azure Policy is the cornerstone of compliance enforcement. It allows you to create, assign, and manage policies that enforce rules and effects over your Azure resources.

   

• Built-in Policies: Azure provides a vast library of built-in policies for common governance, security, and compliance requirements (e.g., "Require encryption on storage accounts," "Allowed locations," "Only allow certain VM sizes").

   

• Custom Policies: Create custom policies in JSON for specific organizational rules not covered by built-ins.

   

• Policy Initiatives (Sets): Group related policies into initiatives (like a single assignment for multiple rules) to simplify management and ensure comprehensive coverage for specific compliance standards (e.g., an "ISO 27001 compliance initiative").

   

• Effects: Policies can have various effects:

  • Audit: Reports non-compliance without blocking actions. Good for initial deployment and monitoring.

     

  • Deny: Prevents the creation or modification of non-compliant resources. Highly effective for strong enforcement.

     

  • DeployIfNotExists (DINE): Automatically deploys a resource or configuration if a non-compliant resource is detected (e.g., automatically deploys diagnostic settings).

  • Modify: Alters resource properties to enforce compliance (e.g., adding tags).

     

• Regulatory Compliance Dashboard: Azure Policy includes a regulatory compliance dashboard that maps built-in and custom policies to common industry standards, providing a clear overview of your compliance posture.

   

Azure Blueprints:

• Standardized Environments: Think of Azure Blueprints as a packaging service that allows you to define a repeatable set of Azure resources, along with policies, RBAC assignments, and ARM templates, into a single, deployable unit.

   

• Consistent Deployments: Blueprints ensure that new environments (e.g., for new projects or teams) are deployed consistently and in accordance with your organization's standards and compliance requirements from day one.

   

• Version Control: Blueprints support versioning, allowing you to track changes and push updates to multiple assigned environments.

   

• Resource Locking: Blueprints can apply resource locks to prevent tampering with foundational infrastructure after deployment.

   

Azure Role-Based Access Control (RBAC):

• Least Privilege: Implement the principle of least privilege, granting users and service principals only the necessary permissions to perform their tasks.

   

• Granular Control: Assign built-in roles (e.g., Contributor, Reader, Owner, specific service roles) or create custom roles to define granular permissions.

   

• Segregation of Duties: Use RBAC to enforce segregation of duties, ensuring no single user has excessive control over critical systems.

   

• Access Reviews: Regularly review and audit RBAC assignments to ensure they are still appropriate and remove stale access.
