Use this procedure to disable individual protocols or cipher suites as by using the
Security Options page in the
SMU Administration menu.
By default, all protocols and cipher suites are enabled. However, occasionally a protocol or cipher suite may be no longer secure and you can use the
Security Options page to prevent a browser from communicating with the
SMU using that protocol or suite.
Before you begin
It is necessary to have at least one protocol and cipher suite remain enabled.
Note It is possible to lose
SMU access by disabling too many protocols or cipher suites. If this happens, a warning will appear in your browser. To recover, use the
SMU-only CLI command to reset both protocols and cipher suites to defaults. See the man pages for the
smu-reset-tls-options command.
Procedure
Navigate to
Home>SMU Administration>Security Options to display the
Security Options page.
By default, all protocols and cipher suites are enabled.
To disable protocols, at

Click the
apply
button at the bottom of the page to apply your changes.
Confirmation dialog boxes appear, and then the
