Out of the box SQL Server queries and results are passed to and from the client and server in an unencrypted format which can be viewed easily from network traffic capture tools. SQL Server network traffic may contain sensitive data such as personal or financial details that need to be protected from unauthorised parties. See Synergetic Data Privacy and Security Information Sheet for for more information on the types of data and data breach rules that may apply to your organisation. To protect network traffic transmissing SQL Server provides native facility to encrypt traffic between the client and server, rendering captured network packets as unreadable and keeping any data transferred confidential whilst it is in transit.

IssueWorkaround

Crystal Reports fail from Synmain when TLS 1.0 is disabled

Cause:

Synergetic 'ODBCAutoConfig' and File > Workstation Config defaults to using SQLSRV32.DLL

This is due to the default ODBC driver SQLSRV32.DLL which does not support TLS 1.1+

Disable ODBCAutoConfig (HKLM\Software\Wow6432Node\ComputingDirections\ODBCAutoConfig = 0) - note that this cannot be disabled in multi-tenant environments at this stage.

Change ODBC reg setting to use newer SQL driver

Key: HKCU\Software\ODBC\odbc.ini\Synergetic\Driver

Value: 'C:\Windows\system32\sqlncli11.dll'


The ODBC settings will require manual update via reg key import to switch between environments (prod/dev/test) or tenants in a  multi-tenant environment.

Then reboot the SQL server(s) to apply the settings.

Important Note: third party dependencies will need to be tested to ensure that they support TLS 1.2. For example if the SQL Server also needs to send emails via TLS it is important to test that the mail server will support TLS 1.2. For example, one issue encountered whilst we were testing was sending email via smtp.office365.com, the following error was returned via the sample Powershell command 'Send-MailMessage : The client and server cannot communicate, because they do not possess a common algorithm'. This required the TLS 1.1 and 1.0 Client Protocols to be reactivated to be able to send emails successfully.
