Securing storage endpoints

This article explains how to secure your storage account endpoints using robust networking rules. By following these guidelines, you can control and restrict access to your storage resources, ensuring secure and efficient communication.

When you access the Networking blade in your storage account, you will observe that public network access is enabled by default. However, you have several options to enhance security:

• Restrict public access by selecting specific virtual networks or IP addresses.
• Disable public network access completely.
• Integrate your existing virtual networks or create new ones for communication through service endpoints.
• Add designated IP ranges from your organization to the firewall for precise access control.

Key Security Capabilities for Storage Accounts

Storage accounts are equipped with built-in security features that provide comprehensive protection:

• Encryption:
  All data stored in your storage account is encrypted by default using Storage Service Encryption (SSE). No additional configuration is required, ensuring data remains secure at rest.

• Authentication:
  Leveraging Azure Active Directory (Azure AD) and Role-Based Access Control (RBAC), you can authenticate requests and authorize access to your storage accounts with fine-grained control.

• Data in Transit:
  Data is protected during transfer through HTTPS, client-side encryption, and protocols such as SMB 3.0. Additionally, Azure Disk Encryption secures the operating system and data disks in both Linux and Windows virtual machines.

• Shared Access Signatures (SAS):
  SAS tokens provide granular control by defining which operations can be performed on your storage account, enhancing overall security and access management.
