Network connections between a JEE client and CICS can be secured by the Secure Sockets Layer (SSL) protocol, or the Transport Layer Security (TLS) protocol.
TLS is an industry-standard SSL protocol. The TLS specification
is documented in RFC2246; for more information, see RFC Index Search Engine.
All references to SSL in this information center also apply to TLS. Connections that require encryption automatically use the TLS protocol, unless the client specifically requests SSL. For more information on configuring CICS Transaction Gateway to use network security, see Configuring SSL.
No special configuration or upgrade tasks are required for using TLS, when compared with SSL.
