Feature enhancements to Azure Web Application Firewall (WAF)

Azure’s global Web Application Firewall (WAF) running on Azure Front Door, and Azure’s regional WAF running on Application Gateway, now support additional features that help organizations improve their security posture and make it easier to manage logging across resources:

• SQL injection (SQLi) and cross site scripting (XSS) detection queries: new Azure WAF analytics SQLi and XSS detection rule templates simplify the process of setting up automated detection and response with Microsoft’s security incident & event management (SIEM) service: Microsoft Sentinel.
• Azure policies for WAF logging: the regional WAF on Application Gateway and the global WAF running on Azure Front Door now have built-in Azure policies requiring resource logs and metrics. This allows organizations to enforce standards for WAF deployments to collect logs and metrics for further analysis and insights related to security events.

In addition, Azure regional WAF on Application Gateway now has:

• Increased exclusion limit: CRS 3.2 or greater ruleset now supports exclusions limit up to 200, a 5x increase from older versions; allowing for greater customization on how the WAF handles managed rulesets.
• Bot Manager ruleset exclusion rules: exclusions are extended to Bot Manager Rule Set 1.0. Learn more: WAF exclusions.
• Uppercase transform on custom rules: you can now handle case sensitivity when creating custom WAF rules using uppercase transform in addition to the lowercase transform.

Storage

Azure NetApp Files cross-zone replication (preview)

The cross-zone replication feature allows you to replicate your Azure NetApp Files volumes asynchronously from one Azure availability zone (AZ) to another in the same region. It uses a combination of the SnapMirror® technology used with cross-region replication and the new availability zone volume placement feature, to replicate data in-region; only changed blocks are sent over the network in a compressed, efficient format. It helps you protect your data from unforeseeable zone failures, without the need for host-based data replication. This feature minimizes the amount of data required to replicate across the zones, therefore limiting data transfers required and also shortens the replication time, so you can achieve a smaller restore point objective (RPO). Cross-zone replication doesn’t involve any network transfer costs, and hence it is highly cost-effective.

Storage

Azure File Sync agent v15.1

Improvements and issues that are fixed:

• Low disk space mode to prevent running out of disk space when using cloud tiering. Low disk space mode is designed to handle volumes with low free space more effectively. On a server endpoint with cloud tiering enabled, if the free space on the volume reaches below a threshold, Azure File Sync considers the volume to be in Low disk space mode. In this mode, files are tiered to the Azure file share more proactively and tiered files accessed by the user will not be persisted to the disk. To learn more, see the low disk space mode section in the Cloud tiering overview documentation.
• Fixed a cloud tiering issue that caused high CPU usage after v15.0 agent is installed.
• Miscellaneous reliability and telemetry improvements.

To obtain and install this update, configure your Azure File Sync agent to automatically update when a new version becomes available or manually download the update from the Microsoft Update Catalog.

More information about this release:

• This release is available for Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 and Windows Server 2022 installations.
• The agent version for this release is 15.1.0.0.
• Installation instructions are documented in KB5003883.

Immutable storage for Azure Data Lake Storage

Immutable storage for Azure Data Lake Storage is now generally available. Immutable storage provides the capability to store data in a write once, read many (WORM) state. Once data is written, the data becomes non-erasable and non-modifiable and you can set a retention period so that files can’t be deleted until after that period has elapsed. Additionally, legal holds can be placed on data to make that data non-erasable and non-modifiable until the hold is removed.

Improved Append Capability on Immutable Storage for Blob Storage

Immutable storage for Blob Storage on containers (which has been generally available since September 2018) now includes a new append capability. This capability, titled “Allow Protected Appends for Block and Append Blobs”, allows you to set up immutable policies for block and append blobs to keep already written data in a WORM state and continue to add new data. This capability is available for both legal holds and time-based retention policies.

Encrypt managed disks with cross-tenant customer-managed keys

Customers of service providers can now use cross-tenant customer-managed keys to manage encryption keys in their own Azure AD tenant and subscription using Azure Key Vault. As a result, they will have complete control of their customer-managed keys and their data.

Azure Dedicated Host support for Ultra Disk Storage

Virtual machines (VMs) running on Azure Dedicated Host support the use of standard and premium disks as data disks, and now there is also the support for ultra disks on dedicated host.

Azure unmanaged disks will be retired on 30 September 2025

Azure Managed Disks now have full capabilities of unmanaged disks and other advancements. Microsoft will begin deprecating unmanaged disks on September 30, 2022, and this functionality will be completely retired on September 30, 2025.

Encryption scopes on hierarchical namespace enabled storage accounts (preview)

Encryption scopes introduce the option to provision multiple encryption keys in a storage account with hierarchical namespace. Using encryption scopes, you now can provision multiple encryption keys and choose to apply the encryption scope either at the container level (as the default scope for blobs in that container) or at the blob level. The preview is available for REST, HDFS, NFSv3, and SFTP protocols in an Azure Blob / Data Lake Gen2 storage account. The key that protects an encryption scope may be either a Microsoft-managed key or a customer-managed key in Azure Key Vault. You can choose to enable automatic rotation of a customer-managed key that protects an encryption scope. When you generate a new version of the key in your Key Vault, Azure Storage will automatically update the version of the key that is protecting the encryption scope, within a day.

Customer initiated storage account conversion (preview)

The self-service option to convert storage accounts from non-zonal redundancy (LRS/GRS) to zonal redundancy (ZRS/GZRS) is available. This allows you to initiate the conversion of storage accounts via the Azure portal without the necessity of creating a support ticket.
