Preparing for the Deprecation of TLS 1.0 and 1.1 in Azure Databases
Microsoft announced the retirement of TLS 1.0 and TLS 1.1 for Azure Services, including Azure SQL Database, Azure SQL Managed Instance, Cosmos DB, and Azure Database for MySQL by August 31, 2025. Customers are required to upgrade to a more secure minimum TLS protocol version of TLS 1.2 for client-server connections to safeguard data in transit and meet the latest security standards. The retirement of TLS 1.0 and 1.1 for Azure databases was originally scheduled for August 2024. To support customers in completing their upgrades, the deadline was extended to August 31, 2025. Starting August 31, 2025, we will force upgrade servers with minimum TLS 1.0 or 1.1 to TLS 1.2, and connections using TLS 1.0 or 1.1 will be disallowed, and connectivity will fail. To avoid potential service interruptions, we strongly recommend customers complete their migration to TLS 1.2 before August 31, 2025. Why TLS 1.0 and 1.1 Are Being Deprecated TLS (Transport Layer Security) protocols are vital in ensuring encrypted data transmission between clients and servers. However, TLS 1.0 and 1.1, introduced in 1999 and 2006 respectively, are now outdated and vulnerable to modern attack vectors. By retiring these versions, Microsoft is taking a proactive approach to enhance the security landscape for Azure services such as Azure databases. Security Benefits of Upgrading to TLS 1.2 Enhanced encryption algorithms: TLS 1.2 provides stronger cryptographic protocols, reducing the risk of exploitation. Protection against known vulnerabilities: Deprecated versions are susceptible to attacks such as BEAST, POODLE, and others TLS 1.2 addresses. Compliance with industry standards: Many regulations, including GDPR, PCI DSS, and HIPAA, mandate the use of secure, modern TLS versions. How to Verify and Update TLS Settings for Azure Database Services For instructions on how to verify your Azure database is configured with minimum TLS 1.2 or upgrade the minimum TLS setting to 1.2, follow the respective guide below for your database service. Azure SQL Database and Azure SQL Managed Instance The Azure SQL Database and SQL Managed Instance minimum TLS version setting allows customers to choose which version of TLS their database uses.

Upgrade to TLS 1.2 now to prepare for this change and maintain secure, compliant database connectivity settings.
Replication lag metric for Azure SQL DB is now in public preview
Azure SQL Database offers business continuity capabilities to recover quickly from regional disasters. Features such as active geo-replication and failover groups provide continuous replication of the data in your primary database to a secondary database in a different Azure region. In the event of a regional disruption, these features allow you to perform quick disaster recovery to your secondary database to meet your business' recovery time objective (RTO) and recovery point objective (RPO). RTO for Azure SQL Database is typically less than 60 seconds, but RPO depends on the amount of data changes before the disruptive event that have not been replicated. Consequently, monitoring the replication lag between the primary and secondary databases is critical in ensuring your RPO goals are met. Until now, the main way to measure the replication lag between the primary and secondary databases was with the replication_lag_sec column of the dynamic management view (DMV), sys.dm_geo_replication_link_status from your primary database. With the introduction of the Replication lag metric, you can now monitor lag with respect to RPO in near real time in the Azure portal in addition to using the DMV. Replication lag is a new Azure monitor metric that is emitted at a one-minute frequency and stored up to 93 days. You can visualize the metric in Azure monitor and set up alerts too. The replication lag metric measures the time span in seconds from the point of transaction commit on the primary database and acknowledgement by the secondary database that the transaction log update has been persisted. The replication lag metric is applicable for a database in DTU or vCore purchasing model and in all service tiers (Basic, Standard, Premium, General Purpose, Business Critical & Hyperscale). Both singleton and elastic pool deployments are supported. You can monitor the metric by adding Replication lag (preview) from your primary database in the portal as shown below: The metric provides three dimensions, Partner Database Name, Partner Server Name, and Partner Resource ID that you can use to further filter or split the data to view specific replication links. If your database is configured to send Metrics to Log Analytics under “Diagnostic settings”, you can also query the Replication lag metric data as shown below: Next Steps Learn more about monitoring geo-replication and other commonly used metrics in Azure SQL Database. See how you can achieve your business continuity goals with Azure SQL Database using Active geo-replication and Failover groups. Prepare for disasters with the Disaster recovery checklist Frequently Asked Questions What is the Replication lag and what does it measure? The Replication lag is a new metric in Azure monitor that measures the time span in seconds between the transactions committed on the primary and hardened to the transaction log on the secondary. How do you view the metric in the portal? In the Azure portal, select your primary SQL database and under "Monitoring", select "Metrics". In the "Metrics" dropdown, choose "Replication lag (preview)". What is the granularity of the Replication lag metric? One minute. What is the latency in displaying the Replication lag data in the Metrics screen? Typically, the latency to display the replication lag is less than three minutes. Are there dimensions available for the Replication lag metric? Yes, there are three dimensions available for the metric - Partner Database Name, Partner Server Name, and Partner Resource ID. These dimensions can be used for filtering and splitting the view in the Metrics screen for easier comparison of multiple secondary geo-replicas.
Breaking Limits: Full-Length SQL Audit Statements Now Supported for Azure SQL DB
We’re excited to announce a major enhancement to SQL auditing in Azure SQL Database, the removal of the 4,000-character truncation limit for audit records. What’s Changed? Previously, audit records were limited to storing 4,000 characters for fields like statement and data_sensitivity_information. Any content beyond that threshold was truncated, potentially leaving out critical details from lengthy queries or sensitive data traces. With this update, statements are no longer truncated. Audit logs now capture the entire content of auditable actions, ensuring complete visibility and traceability for security and compliance teams. Why It Matters Improved Security & Compliance: Full-length statements provide better context for threat detection and forensic analysis. Enhanced Customer Experience: No more guessing what was left out—customers get the full picture. Feature Parity with SQL Server and Managed Instance: This update brings Azure SQL Database in line with SQL Server and Managed Instance capabilities, ensuring consistency across environments.Enhanced Server Audit for Azure SQL Database: Greater Performance, Availability and Reliability
We are excited to announce a significant update to the server audit feature for Azure SQL Database. We have re-architected major portions of SQL Auditing resulting in increased availability and reliability of server audits. As an added benefit, we have achieved closer feature alignment with SQL Server and Azure SQL Managed Instance. Database auditing remains unchanged. In the remainder of this blog article, we cover Functional changes Changes Affecting customers Sample queries Call for action Implementation and Notification Time-based Filtering Functional Changes In the current design when server audit is enabled, it triggers a database level audit and executes one audit session for each database. With the new architecture, enabling server audit will create one extended event session at the server level that captures audit events for all databases. This optimizes memory and CPU and is consistent with how auditing works in SQL Server and Azure SQL Managed Instance. Changes Affecting Customers Folder Structure change for storage account Folder structure change for Read-Only replicas Permissions required to view Audit logs One of the primary changes involves the folder structure for audit logs stored in storage account containers. Previously, server audit logs were written to separate folders, one for each database, with the database name serving as the folder name. With the new update, all server audit logs will be consolidated into a single folder which is ‘Master’ folder. This behavior is the same as Azure SQL Managed Instance and SQL Server For Read-Only database replicas, which previously had their logs stored in a read-only folder, those logs will now also be written into the Master folder. You can retrieve these logs by filtering on the new column ‘is_secondary_replica_true’. Please note that the audit logs generated after deployment will adhere to the new folder structure, while the existing audit logs will stay in their current folders until their retention periods expire. Sample Queries To help you adopt these changes in your workflows, here are some sample queries: Current New To Query audit logs for a specific database called "test" SELECT * FROM sys.fn_get_audit_file ('https://testaudit.blob.core.windows.net/sqldbauditlogs/auditpoc/test/ SqlDbAuditing_ServerAudit_NoRetention/2023-01-29/07_06_40_590_0.xel', default, default) SELECT * FROM sys.fn_get_audit_file ('https://testaudit.blob.core.windows.net/sqldbauditlogs/auditpoc/master/SqlDbAuditing_ServerAudit_NoRetention/2023-01-29/07_06_40_590_0.xel', default, default) WHERE database_name = 'test'; To query audit logs for test database from read only replica SELECT * FROM sys.fn_get_audit_file ('https://testaudit.blob.core.windows.net/sqldbauditlogs/auditpoc/test/SqlDbAuditing_ServerAudit_NoRetention/2023-01-29/RO/07_06_40_590_0.xel', default, default) SELECT * FROM sys.fn_get_audit_file ('https://testaudit.blob.core.windows.net/sqldbauditlogs/auditpoc/master/SqlDbAuditing_ServerAudit_NoRetention/2023-01-29/07_06_40_590_0.xel', default, default) WHERE is_secondary_replica_true = 'true'; Permissions Control database on user database VIEW Database SECURITY AUDIT permission in User Databases Implementation and Notifications We are rolling out this change region-wise. Subscription owners will receive notifications with the subject “Update your scripts to point to a new folder for server level audit logs” for each region as the update is implemented. It is important to update any scripts that refer to the folder structure to retrieve audit logs based on the database name for the specific region. Note that this change applies only to server-level auditing; database auditing remains unchanged. Call for Action These actions apply only to customers who are using storage account targets. No action is needed for customers using Log Analytics or Event hubs. Folder references: Change the reference for audit logs from the database name folder to the Master folder and use specific filters to retrieve logs for a required database. Read -Only Database Replicas: Update references for audit logs from the Read-Only replica folder to the Master folder and filter using the new parameter as shown in the examples. Permissions: Ensure you have the necessary control server permissions to review the audit logs for each database using fn_get_audit_file. Manual Queries This update also applies to manual queries where you use fn_get_audit_file to retrieve audit logs from the storage account Time-based filtering To enhance your ability to query audit logs using filters, consider using efficient time-based filtering with the fn_get_audit_file_v2 function. This function allows you to retrieve audit log data with improved filtering capabilities.
