Enable protocol encryption. Encryption is a method for keeping sensitive information confidential by changing data into an unreadable form. Encryption ensures that data remains secure by keeping the information hidden from all users, even if they view the encrypted data directly.
If you want to use encryption with a failover cluster, you must install the server certificate with the fully qualified DNS name of the virtual server on all nodes in the failover cluster. For example, if you have a two-node cluster, with nodes named test1.redmond.corp.microsoft.com and test2.redmond.corp.microsoft.com and a virtual SQL Server "Virtsql", you need to get a certificate for "virtsql.redmond.corp.microsoft.com" and install the certificate on both nodes. You can then check the Force protocol encryption check box on the Server Network Utility to configure your failover cluster for encryption.
