As a best practice, securing a SmartLock cluster is recommended using either SyncIQ encryption or a pre-shared key. Configuring encryption is preferred. However, for environments where it is not possible, the pre-shared key (PSK) is recommended.
SmartLock Compliance mode clusters do not support SyncIQ PSK. For clusters in SmartLock Compliance mode, upgrading to OneFS 8.2 or later is recommended and configuring SyncIQ encryption. SmartLock Enterprise mode clusters support SyncIQ PSK.
For more information about configuring SyncIQ encryption or a PSK, see SyncIQ security.
