Encryption in Use (Confidential Computing)
Encryption in use protects data while it is being processed. This is typically the hardest state to protect because data must be decrypted for processing. However, Azure offers services that provide the capability to encrypt sensitive data while in use:
- Azure Confidential Computing: This service offers a secure platform for data processing by isolating the computation in a Trusted Execution Environment (TEE), also known as an enclave. This can prevent unauthorized access or modification of applications and data while in use, thereby increasing security for sensitive data.
Key Management and Controls
The effectiveness of encryption is only as good as the management of the encryption keys. Azure provides robust key management through Azure Key Vault:
- Azure Key Vault: This is designed to safeguard cryptographic keys and secrets used by cloud applications and services. Key Vault streamlines the key management process and enables customers to maintain control of keys that encrypt their data.
- Bring Your Own Key (BYOK): Azure allows organizations to bring their own encryption keys for services like Azure Information Protection and Azure Disk Encryption. This offers greater control over the key lifecycle.
- Azure Dedicated HSM: For organizations that require dedicated Hardware Security Modules (HSMs) to manage keys, Azure offers the Azure Dedicated HSM service, which enables customers to manage their HSMs in the cloud.
Compliance and Certifications
Azure’s encryption capabilities align with various compliance protocols and certifications, helping organizations meet the requirements of various industry standards and regulations, such as GDPR, HIPAA, FedRAMP, and more.
Conclusion
In summary, Azure’s data encryption options are part of a multi-layered security approach that defends against a spectrum of threats and vulnerabilities. Whether an organization is storing simple files, hosting web applications, or running complex databases, Azure provides encryption tools to secure sensitive data and uphold the trust of stakeholders and customers alike. The effectiveness of these tools is amplified when coupled with other Azure security features, such as network security and identity management, making Azure a formidable platform for data protection.
