3 Secure the database connection Secure the database connection Introduction In UNICORN 7.0. and later it is possible to use either server side encryption (default) or client side encryption with certificates to ensure a secure database communication. Server side encryption on an SQL Server Microsoft does not recommend to have both server side encryption and client side encryption turned on. Enable server side encryption on the SQL Server by following the instructions. Step Action Log in as an Administrator on the database server computer. Start the SQL Server Configuration Manager.

4 Secure the database connection Step 3 Action Click SQL Server Network Configuration, right-click Protocols for UNICORN and then click Properties. Result: The Protocol for UNICORN Properties dialog box opens Double-click Force Encryption and click Yes. Click OK. Restart the SQL Server service for UNICORN or restart the computer. Server side encryption on the SQL Server installed by UNICORN Microsoft does not recommend to have both server side encryption and client side encryption turned on. Server side encryption is turned on by default when the express edition of SQL Server is installed by the UNICORN installation program. You can turn the server side encryption on and off in the UNICORN Configuration Manager. Step Action Log in as an Administrator on the database server computer. Start the UNICORN Configuration Manager. 4 UNICORN Hardening Guide AA

5 Secure the database connection Step Action Select or clear the Force Encryption check box to turn server side encryption on or off. Click OK. Click Yes in the message box to restart the UNICORN SQL server instance and apply the new setting or No to apply the settings after next UNICORN SQL Server instance restart. Client side encryption with trusted certificates Microsoft does not recommend to have both server side encryption and client side encryption turned on. Follow the instructions to configure UNICORN to use trusted certificates. This document does not describe certificates handling in detail. It is assumed that the local IT department will assist with that. Stage Description Create certificates and have them signed by an Authorized organization. Certificates can be created with a number of different tools. E.g., OpenSSL Makecert IIS Management Console Windows Server AD certificate services. Certificates have a lifetime of to 3 years and need to be reissued after they have expired. Install certificates on every UNICORN client. Depending on the certificates installed the fully qualified domain name (FQDN) for the database location might be needed. Use the Control Panel on the computer running the database to locate the FQDN. See Identify the fully qualified domain name, on page 8 UNICORN Hardening Guide AA 5

6 Secure the database connection Stage Description Use the UNICORN Service Tool to edit the UNICORN client configuration files to use encryption and to not trust server certificates. See UNICORN Service Tool User Manual Install certificates on the database server. On the database server, use the SQL Server Configuration Manager to set certificates for the SQL server UNICORN instance: Expand SQL Server Network Configuration. In Protocols for UNICORN choose Properties. 3 In Protocols for UNICORN Properties window, click on Certificates tab to set the certificate. If you are no longer using certificates, clear SQL Server usage of certificates prior to deleting certificates from the computer. SQL Server will not start without the configured certificate. 6 Check that the client connections are encrypted. See Check client connections, on page 7. Tip: If the connections are refused it is possible that the certificates are not properly installed. Client side encryption without trusted certificates Microsoft does not recommend to have both server side encryption and client side encryption turned on. Follow the instructions to set up client side encryption without using trusted certificates Stage Description Use the UNICORN Service Tool to edit the UNICORN client configuration files to use encryption and to trust all server certificates. See UNICORN Service Tool User Manual Check that the client connections are encrypted. See Check client connections, on page 7. 6 UNICORN Hardening Guide AA

7 Secure the database connection Check client connections You can check the encryption status of current client connections by running the following SQL script. To execute an SQL script there are two options; execute it directly in SQL Server Management Studio or save the script to a text file and execute it using sqlcmd from an elevated command line. SELECT session_id, encrypt_option FROM sys.dm_exec_connections go sp_who The result of the first query is a list of the connections established to the current instance of SQL Server and the details of each connection. The second query returns a list of session ID (spid) and connection information. By cross-referencing these two lists you can check if the connections from a specific computer (hostname) are encrypted. UNICORN Hardening Guide AA 7

8 Secure the database connection Identify the fully qualified domain name The fully qualified domain name (FQDN) is also called "full computer name". Follow the instruction to identify a computer's FQDN. Step 3 Action Enter Computer name in the Windows Start menu search box. Click the See the name of this computer Control Panel item displayed as a result. The FQDN for the computer is listed as "Full computer name" under the heading "Computer name, domain, and workgroup settings". 8 UNICORN Hardening Guide AA

9 Secure the Active Directory connection Secure the Active Directory connection Introduction UNICORN 7.0. and later are by default configured to use secure (encrypted) user authentication with an Active Directory (AD) using the TLS/SSL-protocol. In order to secure user authentication between an Active Directory and the client a trusted relationship must be established (using certificates). This can be done by your local IT department by adding the Server Role Active Directory Certificate Services in Server Manager. Encrypt user authentication with the Active Directory The following table outlines the process of enable or disable encrypting user authentication with an Active Directory. Stage Description Establish a trusted relationship using certificates between the Active Directory and the AD-user. Enable or disable encrypted user authentication to the Active Directory in UNICORN using the UNICORN Service Tool. See UNICORN Service Tool User Manual UNICORN Hardening Guide AA 9
