Final answer:
Azure Backup encryption provides security by encrypting data at rest with Azure Storage Service Encryption or Azure Backup server encryption using 256-bit AES. It also ensures data is encrypted in transit using TLS, offers customer-managed keys through Azure Key Vault, provides granular permissions via RBAC, and stays compliant with industry standards.
Step-by-step explanation:
Azure Backup encryption is an essential feature for protecting data stored in the cloud. When using Azure Backup, your data is encrypted to ensure security during transmission and while it's stored in the Azure cloud. Here are some core features of Azure Backup encryption:
- Data Encryption at Rest: All data stored via Azure Backup is encrypted at rest using Azure Storage Service Encryption (SSE) or Azure Backup server encryption. The data is encrypted using 256-bit Advanced Encryption Standard (AES), ensuring that it is protected against unauthorized access.
- Encryption In Transit: Azure Backup also encrypts your data while it is in transit. This means that any data being sent to or from Azure is safeguarded using Transport Layer Security (TLS) to prevent interception by malicious actors.
- Customer-managed keys: Azure allows clients to control and manage their encryption keys for an additional layer of security. Clients can use the Azure Key Vault to maintain control over the encryption keys, which regulates access and maintains audit logs of key usage.
- Granular permissions: With Azure Backup, you can set granular access permissions to control who can access your backup data. Utilizing Role-Based Access Control (RBAC), you can ensure only authorized personnel have the ability to decrypt and manage the backups.
- Compliance: Azure Backup maintains compliance with various industry certifications and standards, which often require data to be encrypted at rest and in transit.
