Safety
Safety of user accounts
Set a strong access password during initial commissioning. Use passwords that you have
received from the administrator only for the first login.
Keep passwords secret and use a password manager with two-factor login as memory aid, e.g.
Keepass.
Updates
The device supports various update options. A detailed overview is available in Chapter 8.5.2
"System settings - Firmware update" on page 61.
Backup / Restoration
The user can backup / restore device settings. To perform the backup the user must enter a
password. This password is used as safety key to encrypt the backup information. If the user
wants to restore the device settings via a backup file, he must first enter the defined password
so that the backup information can be decrypted.
Solutions for protection against malware
The product is not susceptible to malware, because a user-defined code cannot be executed on
the system. The only option of updating the software is the update of the firmware. Only a
firmware signed by Busch-Jaeger is accepted.
Password rules
Preset passwords should be changed by the user during the first use of the device.
