Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). Websites use TLS to secure all communications between their servers and web browsers.*

To enable TLSv1.2, add theses properties to the local properties file of where each DevTest component runs, including Workstations:
The second property is to set to use strong Cipher Suites, these would be the Cipher Suites to use with DevTest.
Note on specifying strong cipher suites:
There will be a dependency on the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files being installed. (local_policy.jar and US_export_policy.jar, would normally be in the DEVTEST_HOMEjre\lib\security folder) .
