Siemens recommends operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations
to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore
recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber
incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly
recommends applying the provided security updates using the corresponding tooling and documented procedures made
available with the product. If supported by the product, an automated means to apply the security updates across
multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being
applied, and supervision by trained staff of the update process in the target environment. As a general security measure
Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN).
It is advised to configure the environment according to our operational guidelines in order to run the devices in a
protected IT environment.

Recommended security guidelines can be found here.

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To
operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens'
operational guidelines for industrial security and following recommendations in the product manuals.
