TLS (Transport Layer Security) is a widely
adopted security protocol designed to facilitate privacy and data security for
communications over the Internet. TLS is just an updated, more secure, version
of SSL. We still refer to our security certificates as SSL because it is a more
commonly used term, but when you are buying SSL from Symantec you are
actually buying the most up to date TLS certificates with the option of ECC,
RSA or DSA encryption.
A primary use case of TLS is
encrypting the communication between web applications and servers, such as web
browsers loading a website.
TLS provides you with the ability to encrypt
connections between SQL Server and calling client applications. When a client requests an encrypted
connection to a SQL Server configured for TLS, an initial handshake takes place
to negotiate the cipher suite from which further communication should take
place. Once agreed, SQL Server then
sends its TLS certificate to the client, which the client must then validate
and trust against its copy of the Certification Authority (CA)
certificate. Finally, providing the TLS
certificate is trusted and it meets certain other requirements, a secure
connection is established.
TLS Background:
We were able to secure
communication channels since SQL Server 2000 and as the cryptographic protocols
have become more and more secure over time, it’s good to see that
Microsoft has continued to ensure that the product hasn't been left
behind. In January 2016, Microsoft announced support for TLS 1.2
encryption for SQL Server 2008, 2008 R2, 2012 and 2014. That
announcement has since been updated to include support for SQL Server 2016 and
2017. Previously, Microsoft only supported SSL encryption in SQL Server,
however given the series of reported vulnerabilities against SSL, Microsoft now
recommends that you move to TLS 1.2 since it is more secure for establishing
the connection.
SQL Server can use Transport Layer Security
(TLS) to encrypt data that is transmitted across a network between an instance
of SQL Server and a client application. The TLS encryption is performed within
the protocol layer and is available to all supported SQL Server clients. The
level of encryption used by TLS, 40-bit or 128-bit, depends on the version of
the Microsoft Windows operating system that is running on the application and
database computers.
In System Registry the following changes need
to be applied to enable the TLS 1.2
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\
SCHANNEL\Protocols\”
