        "text": "Phoenix Contact classic line controllers are developed and designed for use in closed industrial networks. In this approach, the production plant is protected against attacks, especially from the outside, by a multi-level perimeter, including firewalls, and by dividing the plant into OT zones using firewalls.\n\nThis concept is supported by organizational measures in the production facility as part of a security management system. To achieve security here, measures are required at all levels. It must be ensured that logic is always transferred or stored in protected environments.\n\nIt applies to both data in transmission and data at rest. Connections between the engineering tools (Automation Worx Software Suite) and the controller must always be in a locally protected environment or, in the case of remote access, protected by VPN.\n\nProject data should not be sent as a file via email or other transmission mechanisms without additional integrity and authenticity checks. Project data should only be stored in protected environments. Customers using Phoenix Contact classic line controllers are recommended to operate the devices as intended in closed networks or protected with a suitable firewall.\n\nFor general information and recommendations on security measures to protect network-enabled devices, refer to the application note: Application note Security external link\n\nIf a classic line controller can\u0027t be used in protected zones, the OT communication protocols should be disabled. Depending on the controller type, this can be done either via CPU services via console or web-based management. Information on which controllers and from which firmware version onwards communication protocols can be deactivated is described in the application note for classic line controllers or in the manual for the respective controller, which is available for download on the Phoenix Contact website.\nA summary of measures to protect devices based on classic control technology is provided here: Measures to protect devices based on classic control technology",

In this approach, the production plant is protected against attacks, especially from the outside, by a multi-level perimeter, including firewalls, and by dividing the plant into OT zones using firewalls.\n\nThis concept is supported by organizational measures in the production facility as part of a security management system. To achieve security here, measures are required at all levels. It must be ensured that logic is always transferred or stored in protected environments.\n\nIt applies to both data in transmission and data at rest. Connections between the engineering tools (Automation Worx Software Suite) and the controller must always be in a locally protected environment or, in the case of remote access, protected by VPN.\n\nProject data should not be sent as a file via email or other transmission mechanisms without additional integrity and authenticity checks. Project data should only be stored in protected environments. Customers using Phoenix Contact classic line controllers are recommended to operate the devices as intended in closed networks or protected with a suitable firewall.\n\nFor general information and recommendations on security measures to protect network-enabled devices, refer to the application note: Application note Security external link\n\nIf a classic line controller can\u0027t be used in protected zones, the OT communication protocols should be disabled. Depending on the controller type, this can be done either via CPU services via console or web-based management. Information on which controllers and from which firmware version onwards communication protocols can be deactivated is described in the application note for classic line controllers or in the manual for the respective controller, which is available for download on the Phoenix Contact website.\nA summary of measures to protect devices based on classic control technology is provided here: Measures to protect devices based on classic control technology",
