They provide a description of this configuration at https.. System SSL ships with 10 cipher suites supported. The supported cipher specification list is affected by the SSL protocols that are supported by the system as well changes made to the system value QSSLCSL These rules are called Cipher Suites. They are needed to help secure network connections that use SSL during the handshake. To receive the A+ grade on SSL Labs, there are a few necessary Cipher Suites to add to the configuration file TLS/SSL, SChannel and Cipher Suites in AD FS. The Transport Layer Security (TLS) and Secure Sockets Layer (SSL) are protocols that provide for secure communications. Active Directory Federation Services uses these protocols for communications

Whilst recommended cipher suites constantly evolve a minimum baseline should be set and updated periodically and then baked into the security hardening policy or build guide. This should not only be set at the time of build, administrators should constantly update the cipher lists in order for their systems..
