How to Enable SSL/TLS Encryption on SQL Server (Step-by-Step). SQL Server traffic can be readable on the wire when encryption isn’t enforced. In this admin-focused walkthrough, you’ll learn how to enable SSL/TLS for SQL Server using a CA-issued certificate, apply it in SQL Server Configuration Manager, fix the common “service won’t start” private key permission issue, and validate encryption using SSMS, ODBC Driver 18, and Wireshark. You’ll learn: 🧠🛠️ • Identify clear-text TDS traffic and why it happens • Certificate requirements for SQL Server (SAN/FQDN, EKU, RSA 2048+) • Apply a TLS certificate to the SQL Server instance in SQL Server Configuration Manager • Fix private key permissions for least-privilege SQL service accounts • SSMS Encrypt modes: Optional vs Mandatory vs Strict (and why name matching matters) • ODBC Driver 18 encryption settings (including Strict) and DSN testing • Verifying encryption using Wireshark (TDS vs. TLS traffic) • Solving "Target Principal Name is incorrect" errors in Mandatory and Strict modes Target Audience: IT Pros / Sysadmins / Students / Cloud engineers Skill Level: Intermediate / Advanced Applies to: ✅ Windows 11 ✅ Windows Server 2016 – 2025 ✅ MSSQL Server 2019 – 2025 (may apply to some earlier versions) Hashtags: #SQLServer #CyberSecurity #TLS #SSL #Encryption #MSSQL #SysAdmin #DatabaseAdministration #TechTips #DarienTips Commands and Scripts GitHub: https://github.com/DariensTips SELECT @@SERVERNAME AS ServerName, DB_NAME() AS DatabaseName, @@SPID AS SessionID, s.host_name AS ClientHost, s.program_name AS ProgramName, c.client_net_address AS ClientIP, c.local_net_address AS ServerIP, c.local_tcp_port AS ServerPort, c.protocol_type AS Protocol, c.encrypt_option AS EncryptOption, c.auth_scheme AS AuthScheme FROM sys.dm_exec_connections c JOIN sys.dm_exec_sessions s ON c.session_id = s.session_id WHERE c.session_id = @@SPID; Chapters: 00:00 Introduction 00:42 SQL Server Default Settings 02:11 Obtain CA TLS Certificate 03:51 Secure SQL Server Instance 05:34 Connect to Secure Instance Using SSMS 08:02 Connect to Secure Instance Using ODBC 10:16 Environment 11:09 Links & Resources 11:36 Thank you for watching 11:58 Operational Mindset Links & Resources: https://learn.microsoft.com/en-us/sql... https://learn.microsoft.com/en-us/tro... https://learn.microsoft.com/en-us/tro... https://learn.microsoft.com/en-us/tro...

Always test certificate changes and Force Encryption / Strict encryption settings in a non-production environment first—enforcing TLS can break legacy clients, older drivers, and connections that use a hostname not listed in the certificate SAN (FQDN/alias/CNAME/AG listener). “Trust Server Certificate” is shown only for troubleshooting; production deployments should validate the certificate chain (CA/PKI) and server name properly. Your results may vary based on your AD CS/PKI configuration, TLS/cipher policy, and client driver versions. Attribution: Creme Brulee - The Soundlings (YouTube Audio Library)
