You can manually select the specific SSL ciphers used by the appliance by editing the SSL device profile.
To remove the low strength SSL ciphers:
- In the Management Console, go to Configuration > SSL > Device Profiles > Default, and click Edit (choose your specific keyring if configured here).
- Click Edit Ciphers at the bottom right of the window.
- Highlight the low strength ciphers on the right hand side, and click Remove. This de-selects the low strength ciphers from the appliance SSL device profile. They will no longer be used for SSL negotiations.
- Click OK, OK, and Apply.
