Other Considerations in Mitigating Cybersecurity

● Communication between the Intelligent Valve and Siemens Digital Services is

via the Internet where connection is always outbound traffic, initiated by

Intelligent Valve on premise, utilizing HTTPS and MQTTS.

● All data communication via the Internet is encrypted using Transport Layer

Security (TLS) 1.2 and utilizes TCP port 443. Utilizing TLS ensures data

transferred is highly resistant to eavesdropping and interception. No other port

is used for outbound (to the internet) data communication.

● All data communication between the Cloud servers’ endpoints and Intelligent

Valve is secured by means of X509-certificate-based authentication and

authorization.

● Intelligent Valve does not support HTTP proxy.

● Intelligent Valve allows for remote firmware updates initiated by authorized and

authenticated user account within customer's organization for ease-of-use and

fast fixes of security issues if applicable.

● Operational certificates are renewed on a regular base to maximize security.

On-premise IT/OT Network and Intelligent Valve

● Ensure Intelligent Valve installation and cloud setting configuration follows the

Intelligent Valve Engineering Guide and chooses the right network

configuration option.

● Administrator credentials for Intelligent Valve should not be shared.
