+### Forcing TLS 1.2
+
+Some applications may want to force only the TLS 1.2 protocol. To do this, set the `jdk.tls.client.protocols` system property to "TLSv1.2".
+
+Java runtime environments prior to Java 8 started to enable the TLS 1.2 protocol only in later updates, as shown in the previous section. For the driver to force the use of the TLS 1.2 protocol with a Java runtime environment prior to Java 8, ensure that the update has TLS 1.2 enabled.
