scenarios: GENERAL
workarounds:
To minimize the risk of unauthorized access to sensitive information, ABB recommends to only operate
Flow-X flow computers in secure networks.
Additionally, ABB recommends that HTTPS is used to communicate with the Flow-X web server. HTTPS
support has been implemented since version 1.2.2 (available as of June 2016) and is enabled by default
since version 3.2.0 (available as of September 2020).
To minimize the risk of exposed security information on one device leading to unauthorized access on
other devices, ABB recommends that customers change the usernames and passwords that are part of
the standard application and to use different usernames and password on different devices
