23 Securing the Device
The C500 has been designed with security in mind, however steps must be taken by the user on first use to
secure the instrument against malicious actors.
23.1 Setting a Safe and Full Passcode
The safe and full passcode should be configured by the user to prevent access to the device setup menus.
Passcodes can be set with the instrument’s physical interface using the methods covered in Section 5.1.2, or
remotely using Network Commands (see Section 21.3.16).
23.2 Changing the Web Interface Passcode
The web interface controls access to the syslog and the installed packages. This interface must be secured to
prevent malicious actors from tampering with the scale operation by removing critical packages.
To change the default password:
1. Follow the steps outlined in Section 26.2.1 to access the web interface.
2. From the web interface, select ‘User Access’ to open the password change interface.
3. Enter in the old password. By default, this is ‘password’.
4. Enter and re-enter the new password in the appropriate text boxes.
5. Press ‘Change password’ to confirm the change to the password.
23.3 Securing Against Threats via Network
23.3.1 Changing the User Login Password
If the developer package (L900-500) is installed and telnet access is enabled, the user must change the default
password for ‘user’ to secure this interface.
1. Open your telnet client and connect to the device. For this you will need the device IP address (available
via the menus at ETH.NET:IP). The recommended telnet client for Windows is Putty.
2. When prompted for c520-SERIALNUMBER login:, enter ‘user’.
3. When prompted for password:, enter the indicator’s serial number.
