Managing TLS Ciphers
2 minute read.Last Modified 2021-03-03 13:11 EST
This feature was introduced in TrueNAS 12.0
TrueNAS accepts different Transport Layer Security (TLS) cipher suites for secure connections to the web interface. For best security, only use TLS 1.2 or newer. By default, all options are available if you need to adjust this setting to match your particular network environment or security concerns.
Log in to the web interface and go to System > General:
Click on HTTPS Protocols to open a dropdown menu with the various cipher suites.
Unsetting a cipher restricts its use in TrueNAS. After enabling or disabling a cipher, the TrueNAS system must be rebooted.
