Hardening

Recommendations to optimize cybersecurity in a protected environment:

Harden the meter according to your company policies and standards.
Review assumptions about protected environments and address potential risks and mitigation strategies.
Change the default passwords/passcodes (Refer to Configuring the display passcode and Changing user account password).
Enable the HMI timeout period in webpages (Refer to Enabling the HMI timeout period).
Terminate the user account sessions in webpages (Refer to Terminating user account sessions).
Least functionality can be applied to prohibit and restrict the use of unnecessary functions, protocols and/or services.
Change the communication protocol ports from their default values. This lowers the predictability of port use.
Disable communication protocol ports when they are not in use. This reduces the attack surface.
