If you expose connection string altering to systems administrators or application users, leave it up to management personnel. That's all what you shall to do regarding transport security for SQL client. ADO.NET clients use Windows built-in certificate chaining engine to validate server certificate. If TrustServerCertificate is set to False, then client will fail if either, SQL does not implement TLS or server certificate is not valid according to validation rules. If it is set to True, client will fallback to insecure transport (if SQL server does not implement TLS) and will accept arbitrary certificate (potentially, untrusted, or MITM) when presented by server.īy default and when not configured, SQL server automatically generate a self-signed certificate to clients that require secure transport. The available official servers use a proprietary protocol that we call TLSVPN, it is a simple protocol that protects the connection using TLS 1.3 (and TLS 1.2 optionally. The behavior of connection is controlled using TrustServerCertificate connection parameter. TLS Tunnel is a free VPN that aims to cross barriers imposed by internet providers and governments, and to guarantee privacy, freedom and anonymity to users. If you need secure channel to SQL server, just insert encrypt=true in SQL connection string. You don't need to do anything specific in this regard.
