If your system is backward-compatible with older versions of Security Center that do not support the Transport Layer
Security (TLS) protocol (5.4 and earlier), your system is more vulnerable to network
attacks.
What you should know
Mobile
Server 4.0 does not support
Transport Layer Security (TLS) protocol. If you disable backward compatibility, the Mobile
apps and the Web Clients 4.0 can no longer connect to
Security Center. Expansion servers that have not been
upgraded to version 5.5 or later will also stop working. Both
Web
Client 4.1 and the role-based
Web
Client 5.6 and later support TLS.
Procedure
-
Connect to the Server
Admin of your main
server with a web browser.

-
In the Secure communication section, select your current version
of Security Center version from the
Allow applications starting from version (backward compatibility)
list.

Click Save.
IMPORTANT: The next time someone tries to connect to your system with an older
Security Center version, they will get the
Client-server versions are incompatible error.
