To remove a TACACS+ server from the list, click the X-button in the Actions
column.

4.3.7 HTTPS Security Levels
SecureSync supports two different modes of HTTPS operation:
The Standard HTTPS Level allows the use of medium strength ciphers and older
TLS (Transport Layer Security) protocols,
while the High-Security Level is restricted to strong ciphers and TLS version 1.2
exclusively.
While Standard Mode is the default setting, the High-Security Level is preferred (unless
you require the extra compatibility), since High Security turns off TLSv1, which has known
security vulnerabilities.
B r o w s e r S u p p o r t
Note that the High Security Level requires the use of current browsers - as of July 2016, the old-
est compatable clients include:
• Firefox

27
• Chrome
®
30
• Internet Explorer
®
11
• Safari
