12.4.5 How to prevent unauthorized access
The default computer name and user password are instrument. The user password is
the password required for VNC, FTP and SMB (samba) connections. If, for example,
the VNC service or FTP are enabled, anyone in the network who knows the computer
name and user password of the instrument can access it.
The default security password is 123456. The security password is required when
changing the status of the USB and LAN interface.
To prevent unauthorized access, use the following configurations exclusively or com-
plementary:
