I hope that this last script will help you to see the TLS connection type. Before SQL Server 2019 and after SQL Server 2016ĬREATE EVENT SESSION ON SERVERĪLTER EVENT SESSION ON SERVER STATE = START
IF (( CAST(SERVERPROPERTY('ProductMajorVersion') AS INT) 13)) For SQL Server 2014 or 2012, you must use Built-In Diagnostics (BID) traces Before SQL 2016, the Trace extended event is not implemented for the SNI layer.
SQL SERVER CLIENT TLS SSL ERROR INSTALL
I create this query below to go through the CMS (central management server) and install the good version of the sni layer and only after SQL Server 2014: - Create SQL Server extended event to monitor TLS I replace my query by this one for SQL Server 2019: CREATE EVENT SESSION ON SERVERĪfter discussed with my customer, he asks me to implement it on each SQL Server available for the Extended Event. The event name, “ace”, is invalid, or the object could not be foundĪfter a google search session, I find that the ace is replace by sqlsni.sni_trace It’s running fine and I have the first result with some TLS 1.0 and TLS1.2 connections.Īfter that, I want to test also on SQL Server 2019 Instance, I got this error: WITH (MAX_MEMORY=4096 KB,EVENT_RETENTION_MODE=ALLOW_SINGLE_EVENT_LOSS,MAX_DISPATCH_LATENCY=30 SECONDS,MAX_EVENT_SIZE=0 KB,MEMORY_PARTITION_MODE=NONE,TRACK_CAUSALITY=OFF,STARTUP_STATE=OFF) Recently, a security audit revealed that there are a set of cipher suites used in TLS 1.2 that are now considered 'weak'. SSL/TLS connections provide one layer of security by encrypting data that moves between your client and a DB instance. (,N'%TLS%')))ĪDD TARGET package0.event_file(SET filename=N'TLS_Monitoring') (Which means Qlik has to have TLS 1.0 Client enabled and the database server needs TLS 1.0 Server enabled in the Windows registry.) But QlikSenses problems go deeper. You can use Secure Socket Layer (SSL) or Transport Layer Security (TLS) from your application to encrypt a connection to a DB instance running MariaDB, Microsoft SQL Server, MySQL, Oracle, or PostgreSQL.
The only way is to create an Extended Event.Ī big limitation is that the event used is only available on SQL Server 2016 and +.īefore use the Built-In Diagnostics (BID) traces.Īfter I implanted the first TLS Monitoring on a SQL Server 2016 with the query: CREATE EVENT SESSION ON SERVER For a customer, I do some research to find which TLS is used on the SQL Server environment.
