Full-disk encryption and file encryption can help protect files and information that are stored at-rest on your system.To learn more, visit ASU's Get Protected website. Encryption plays a key role in keeping information safe by ensuring that it can't be obtained through theft or eavesdropping.Īdditionally, encryption is one of the 'Top 5 Critical Security Initiatives' at Arizona State University. Federal laws, state statutes, and industry standards apply civil penalties for failure to protect sensitive information adequately. Many ASU personnel routinely handle sensitive information including Personally Identifiable Information (PII), student records, health records, financial records, and research data. In order to be compliant with ASU policy, faculty and staff are required by the university to implement encryption and other standard security measures on all devices accessing the ASU network. Most often, those encrypted files can be seen in a file listing (such as in file explorer), but they can not be accessed for reading by unauthorized persons. Encrypting stored files prevents others from reading, copying, or deleting encrypted files. Encrypted files are usally stored locally and are encrypted and temporarily decrypted while being used and than encrypted again after the user is finished using them. File Encryption means providing security for files that reside on media, in a stored state, such as a hard drives, usb drive, SD Card, or any other type of digital storage medium.Basically, should your computer be lost or stolen, full-disk encryption will protect and secure any sensitive data, and keep any unauthorized persons from gaining access to it. It ensures that if your computer or device is stolen, all data on its disk will be unavailable to the thief. Endpoint encryption software is special software that makes all data on the system inaccessible without a key.If you want to create new node pools without the host-based encryption feature, you can do so by omitting the -enable-encryption-at-host parameter. az aks nodepool add -name hostencrypt -cluster-name myAKSCluster -resource-group myResourceGroup -s Standard_DS2_v2 -l westus2 -enable-encryption-at-host Configure a new node pool to use host-based encryption by using the -enable-encryption-at-host parameter. You can enable host-based encryption on existing clusters by adding a new node pool to your cluster. Use host-based encryption on existing clusters If you want to create clusters without host-based encryption, you can do so by omitting the -enable-encryption-at-host parameter. az aks create -name myAKSCluster -resource-group myResourceGroup -s Standard_DS2_v2 -l westus2 -enable-encryption-at-host Use host-based encryption on new clustersĬonfigure the cluster agent nodes to use host-based encryption when the cluster is created. Requires an AKS cluster and node pool based on Virtual Machine Scale Sets(VMSS) as VM set type.Can only be enabled in Azure regions that support server-side encryption of Azure managed disks and only with specific supported VM sizes.Ensure you have the CLI extension v2.23 or higher version installed. Host-based encryption is available in Azure regions that support server side encryption of Azure managed disks and only with specific supported VM sizes. This feature can only be set at cluster creation or node pool creation time. Host-based encryption uses the host of the VM to handle encryption before the data flows through Azure Storage. Azure-managed disks use Azure Storage to automatically encrypt data at rest when saving data. Host-based encryption is different than server-side encryption (SSE), which is used by Azure Storage. The cache for these disks will then also be encrypted using the key that you specify in this step. You can specify your own managed keys following Bring your own keys (BYOK) with Azure disks in Azure Kubernetes Service. The caches for these disks are also encrypted at rest with platform-managed keys. The cache of OS and data disks is encrypted at rest with either platform-managed keys or customer-managed keys depending on the encryption type set on those disks.īy default, when using AKS, OS and data disks use server-side encryption with platform-managed keys. This means the temp disks are encrypted at rest with platform-managed keys. With host-based encryption, the data stored on the VM host of your AKS agent nodes' VMs is encrypted at rest and flows encrypted to the Storage service.
