In today’s security-conscious world, data encryption is no longer optional—it's a critical requirement. VMware's vSAN Encryption Services provide robust security for data both at rest and in transit, ensuring compliance with organizational and regulatory standards. Here's a closer look at how VMware's latest offerings can protect your infrastructure.
-
Data-at-Rest Encryption:
Protects all data stored on vSAN clusters, encrypting it at the final stage of I/O processing. -
Data-in-Transit Encryption:
Safeguards data transmitted across vSAN hosts without requiring a Key Management Server (KMS).
These services are enabled on a per-cluster basis, offering flexibility depending on your needs.
-
Original Storage Architecture (OSA):
Supports both encryption and space-saving features like deduplication and compression. -
Express Storage Architecture (ESA):
Encrypts data efficiently at the upper layers of the storage stack, minimizing CPU and network overhead.
Organizations can manage encryption keys using either an External Key Management Server (KMS) or the vSphere Native Key Provider (NKP). For enhanced security, VMware recommends using Trusted Platform Modules (TPM) to store keys locally on hosts.
-
Performance Impact:
Encryption is optimized to minimize performance overhead by utilizing advanced AES-NI CPU instructions. -
Rekeying and Secure Wiping:
Both shallow and deep rekey operations are supported, allowing administrators to rotate encryption keys without disrupting operations. Additionally, VMware offers secure device wiping options compliant with NIST standards.
- Enable both data-at-rest and data-in-transit encryption for comprehensive protection.
- Ensure proper DNS configurations for KMS to avoid connectivity issues.
- Implement TPM on all vSAN hosts to improve key persistence and recovery processes.
VMware's vSAN Encryption Services provide scalable and flexible security solutions, helping organizations meet their data protection goals with minimal complexity. Secure your infrastructure today with VMware vSAN!
