If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens Energy strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment.\n\nAs a general security measure Siemens Energy strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN).
