  Manufacturers using ProConOS/ProConOS eCLR in their automation devices are advised to check their implementation and may publish an advisory according to their product. Users of automation devices utilizing ProConOS/ProConOS eCLR in their automation systems may check if their application requires additional security measures like an adequate defense– in-depth networking architecture, the use of virtual private networks (VPNs) for remote access, as well as the use of firewalls for network segmentation or controller isolation. Users should check their manufacturers security advisories for more adequate information according to their dedicated device. Users should ensure that the logic is always transferred or stored in protected environments. This is valid for data in transmission as well as data in rest. Connections between the Engineering Tools and the controller must always be in a locally protected environment or protected by VPN for remote access. Project data shouldn't send as a file via e-mail or other transfer mechanisms without additional integrity and authenticity checks. Project data should save in protected environments only. Generic information and recommendations for security measures to protect network-capable devices can be found in the application note.
