1.3 Notes on information security

Foreword 1.3 Notes on information security The products of Beckhoff Automation GmbH & Co. KG (Beckhoff), insofar as they can be accessed online, are equipped with security functions that support the secure operation of plants, systems, machines and networks. Despite the security functions, the creation, implementation and constant updating of a holistic security concept for the operation are necessary to protect the respective plant, system, machine and networks against cyber threats. The products sold by Beckhoff are only part of the overall security concept. The customer is responsible for preventing unauthorized access by third parties to its equipment, systems, machines and networks.

The latter should be connected to the corporate network or the Internet only if appropriate protective measures have been set up. In addition, the recommendations from Beckhoff regarding appropriate protective measures should be observed. Further information regarding information security and industrial security can be found in our https://www.beckhoff.com/secguide . Beckhoff products and solutions undergo continuous further development. This also applies to security functions. In light of this continuous further development, Beckhoff expressly recommends that the products are kept up to date at all times and that updates are installed for the products once they have been made available.

Using outdated or unsupported product versions can increase the risk of cyber threats. To stay informed about information security for Beckhoff products, subscribe to the RSS feed at https:// www.beckhoff.com/secinfo . TX1200 5 Version: 1.3
