![]() Then, vCenter Server will pass the KMS connection data to the vSAN host.You will do this by exchanging administrative certificates between your KMS and vCenter Server to establish trust.Then, you will need to set up a domain of trust between vCenter Server, your KMS, and your vSAN host.First, install and configure your key management server (such as our Alliance Key Manager) and add its network address and port information to the vCenter KMS Cluster.To prove the point, here is a quick guide to getting encryption up and running for your vSAN clusters: This means that securing your sensitive data with AES encryption is not a time-intensive task. VSAN encryption is easy to enable and use. Only a ESXi host with the key ID information for that VM can properly locate the encryption key for decryption. Once you encrypt a virtual machine, you cannot relocate the VM to a host that does not have the key ID information.If you change the name of the KMS cluster (one that is in use), the ESXi host will be unable to find the KMS and a VM that is encrypted with a key encryption key (KEK) from that KMS will be unable to be decrypted. Once you name your key management server (KMS) cluster, do not rename it.If your primary key server goes down with no failover key server in place, your encrypted VMs will be unable to be decrypted. Always designate a high availability failover key manager in your KMS cluster.Your changes may make the VM unrecoverable. Do not edit either VMX files or VMDK descriptor files as they contain the encryption bundle.These are vital to the functioning of VMware and should never be encrypted. Do not encrypt any vCenter Server Appliance VMs.This means that getting encryption right the first time is paramount.Īs you begin your VM encryption project, keep these in mind to avoid some of the more common pitfalls: Because of this, organizations typically have mission-critical information in VMs. VMs are a powerful tool that helps you realize greater IT efficiencies, reduced operating costs, and achieve unmatched flexibility. ^Back to Top vSphere VM Encryption Best Practices This way, your encrypted data stays safe even if you lose a backup or a hacker accesses your VMware environment. Instead, vCenter Server stores the KEK ID for future reference. The KEK is safely stored in Alliance Key Manager.ESXi then uses the KEK to encrypt the DEK and only the encrypted DEK is stored locally on the disk along with the KEK ID.The vCenter Server then requests a key from Alliance Key Manager.Then, when encrypting, the ESXi host generates internal DEKs to encrypt the VMs, files, and disks.vCenter will provision the encryption keys from the cluster you designate as the default. When you add a KMS cluster, vCenter will prompt you to make it the default.First, install and configure your KMIP compliant key management server (KMS), such as our Alliance Key Manager, and register it to the vSphere KMS Cluster.vSphere encryption allows you to encrypt existing virtual machines as well as encrypt new VMs right out of the box.Īdditionally, vSphere VM encryption not only protects your virtual machine but can also encrypt your other associated files. With vSphere 6.5 and above, you can now encrypt your VMs to help protect sensitive data-at-rest and to meet compliance regulations. If you’d like to first learn the fundamentals of encryption and key management before diving in, please view The Definitive Guide to Encryption Key Management Fundamentals. From there, we will look at best practices, compliance regulations, infrastructure considerations, and much more. To provide insight on how to best deploy encryption and encryption key management in VMware, this comprehensive guide will provide an overview of the powerful encryption capabilities for both VMs and vSAN and how to easily deploy them. We need strong encryption and key management solutions that run natively in our virtual environments and meet compliance regulations. In our increasingly insecure cyber world, VMware understands the critical nature of robust security solutions, including encryption capabilities. VMware’s desktop software runs on Microsoft Windows, Linux, and MacOS, while its enterprise software hypervisor for servers, VMware ESXi, is a bare-metal hypervisor that runs directly on server hardware without needing an additional underlying OS. Today VMware is a top-tier cloud computing and virtualization provider, and a popular solution for organizations moving to the cloud. Shortly thereafter, it was the first commercially successful company to virtualize x86 architecture. The VMware story began in 1998 when five forward-thinking technologists launched an innovative virtualized computing solution. ^Back to Top Introduction: VMware Encryption for Data-at-Rest ![]()
