Hi Kochan Sebastian,

Both Azure Blob Storage and Azure SQL Database offer robust security features, but they cater to different needs and use cases. Here's a comparison to help you decide which might be more secure for your specific requirements

The choice depends on your specific use case and data type. If you need to store and manage structured data with complex queries, Azure SQL Database might be more secure. For unstructured data storage with simpler access requirements, Azure Blob Storage could be the better option.

Azure Blob Storage (CSV)

Data Protection:

• Encryption: Data is encrypted at rest and in transit using AES-256 encryption.
• Soft Delete: Allows recovery of deleted blobs and containers.
• Versioning: Maintains previous versions of blobs to protect against accidental overwrites.

Access Management:

• Azure Active Directory: Supports role-based access control for fine-grained permissions.
• Shared Access Signatures: Provides temporary access to storage resources.

Threat Protection:

• Microsoft Defender for Storage: Detects unusual and potentially harmful attempts to access or exploit storage accounts.

Azure SQL Database

Data Protection:

• Encryption: Transparent Data Encryption for data at rest and Always Encrypted for sensitive data.
• Backup and Restore: Automated backups with point-in-time restore capabilities.

Access Management:

• AAD Integration: Supports multi-factor authentication and RBAC.
• Firewall Rules: IP-based and virtual network-based firewall rules to restrict access.

Threat Protection:

• Advanced Threat Protection: Monitors and detects anomalous activities indicating potential security threats.
• SQL Vulnerability Assessment: Provides a comprehensive security assessment report.

Additional information

Azure Blob Storage is ideal for unstructured data and offers strong encryption, access control, and threat detection features.

Azure SQL Database is better suited for structured data with advanced encryption, access management, and threat protection capabilities.
