Azure - Storage Account Security

Security Measures

1. Network Security:
   • Virtual Network (VNet) Integration: Use VNet service endpoints or private endpoints to restrict access to storage resources from specific VNets.
   • Firewalls and Virtual Networks: Configure firewall rules to allow access from specific IP addresses or ranges.
2. Encryption
   • Encryption at Rest: All data in Azure Storage is encrypted using Microsoft-managed keys by default. You can also use customer-managed keys stored in Azure Key Vault.
   • Encryption in Transit: Data is encrypted using HTTPS to protect data as it travels between the client and Azure Storage.
3. Access Control
   • Role-Based Access Control (RBAC): Assign Azure roles to users, groups, or applications to control access to storage resources.
   • Shared Access Signatures (SAS): Provide fine-grained, time-limited access to storage resources.
4. Advanced Threat Protection
   • Azure Defender for Storage: Provides threat detection and alerts for unusual and potentially harmful attempts to access or exploit storage accounts.
5. Data Redundancy Options
   • Locally Redundant Storage (LRS): Replicates data within a single datacenter.
   • Zone-Redundant Storage (ZRS): Replicates data across multiple datacenters within a region.
   • Geo-Redundant Storage (GRS): Replicates data to a secondary region for additional durability.
   • Read-Access Geo-Redundant Storage (RA-GRS): Allows read access to the replicated data in the secondary region.
6. Auditing and Monitoring
   • Storage Analytics: Provides logging and metrics to monitor storage account activity.
   • Azure Monitor: Integrates with Azure Monitor to provide detailed insights and alerts for storage account operations.
