### MITIGATION

As a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms. In order to run the devices in a protected IT environment, Siemens particularly recommends users configure the environment according to Siemens’ Operational Guidelines for Industrial Security, and follow the recommendations in the product manuals. The Operational Guidelines for Industrial Security can be found at:
