Disable non-secure protocols

Milestone recommends that you use only the necessary protocols, and only the latest versions. For example, implement the latest version of the Transport Layer Security (TLS, currently 1.2) and disable all other cipher suites and obsolete versions of SSL/TLS protocols. This requires configuration of Windows and other system components, and the proper use of digital certificates and keys.

The same recommendation is given for the management server. For more information, see Disable non-secure protocols.
