Security Center systems that are backward-compatible with older versions that do not support the Transport Layer Security (TLS) protocol (5.4 and earlier) are 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 also stop working. Both Web Client 4.1 and the role-based Web Client 5.6 and later support TLS.

Procedure

  1. Connect to the Server Admin of your main server with a web browser.
  2. Click the main server () in the server list.
  3. In the Secure communication section, select your current version of Security Center version from the Allow applications starting from version (backward compatibility) list.
    The Secure communication section of the server in Server Admin with the Allow applications start from version (backward compatibility list highlighted.
  4. Click Save.
    IMPORTANT: The next user who tries to connect to your system with an older Security Center version receives a Client-server versions are incompatible error.
