A security device includes one or more processors and a memory that includes instructions, that when executed by the processors, cause the processors to perform operations. The operations include monitoring data traffic between industrial automation devices in an industrial system and one or more devices in an external network, determining that a first industrial automation device does not include native security features for receiving secure data from the devices in the external network or transmitting secure data to the devices in the external network, and implementing one or more security techniques in response to determining that the first industrial automation device does not include the native security features.

Systems and methods for automatic security enforcement for industrial automation devices

Embodiments of this present disclosure include an industrial automation system, including an operational technology (OT) industrial automation device. The OT industrial automation device may perform an operation for the industrial automation system. Further, the OT industrial automation device may receive data comprising instructions related to the operation. Embodiments also include a monitoring device to receive the data; identify the OT industrial automation device based on the data; retrieve one or more rules for providing communications to the OT industrial automation device in response to identifying the OT industrial automation device; and selectively forward the data to the OT industrial automation device based on the one or more rules.

Network monitoring system for operational technology devices

An OT device includes a processor and a memory, accessible by the processor. The memory stores a first policy that includes a first set of settings associated with operation of the OT device. The memory also stores instructions that, when executed by the processor, cause the processor to enforce the first policy, receive a second policy and an indication of a trigger, wherein the second policy comprises a second set of settings associated with the operation of the OT device, receive an indication that the trigger is enabled, determine that the trigger is true, and, in response to the receiving the indication that the trigger is enabled and the determining that the trigger is true, enforce the second policy.

Systems and methods for scheduled policy deployment in operational technology networks

A model-based industrial security policy configuration system implements a plant-wide industrial asset security policy in accordance with security policy definitions provided by a user. The configuration system models the collection of industrial assets for which diverse security policies are to be implemented. An interface allows the user to define zone-specific security configuration and event management policies for a plant environment at a high-level based on a security model that groups the industrial assets into security zones. Based on the model and these policy definitions, the system generates asset-level security setting instructions configured to set appropriate device settings on one or more of the industrial assets to implement the security event management policies, and deploys these instructions to the appropriate assets in order to implement the defined policies.

Centralized security event generation policy

Techniques for authenticating industrial devices in an industrial automation environment are disclosed herein. In at least one implementation, a physical unclonable function response of an industrial device is extracted. The industrial device transmits a security certificate signed by a certificate authority that includes a device public key to a system, wherein the system validates the security certificate, encrypts an authentication challenge using the device public key, and transmits the authentication challenge to the industrial device. The industrial device generates a device private key using the physical unclonable function response and decrypts the authentication challenge using the device private key. The industrial device generates an authentication response based on the authentication challenge, encrypts the authentication response using the device private key, and transmits the authentication response to the system, wherein the system decrypts the authentication response using the device public key and authenticates the industrial device based on the authentication response.

Use of physical unclonable functions to prevent counterfeiting of industrial control products

Secure data transmission between an input device and both industrial controllers in a high-availability system utilizes a secure connection established between the primary industrial controller and the input device. Data required to establish the secure connection is stored on the primary controller as part of the connection data corresponding to the secure connection. The input device transmits data to the primary controller over the secure connection according to the desired level of security. The primary controller transmits the connection data defining the secure connection to the secondary controller. If a failure occurs in the primary controller, the secondary controller establishes a connection to the input device using the connection data for the secure connection, such that the secondary controller may assume responsibility for the controller end of the secure connection. The primary controller transmits the input signals to the secondary controller via the dedicated connection between controllers.

System and method for secure connections in a high availability industrial controller

A model-based industrial security policy configuration system implements a plant-wide industrial asset security policy in accordance with security policy definitions provided by a user. The configuration system models the collection of industrial assets for which diverse security policies are to be implemented. An interface allows the user to define zone-specific security configuration and event management policies for a plant environment at a high-level based on a security model that groups the industrial assets into security zones. When new industrial devices are subsequently installed on the plant floor, the system determines whether a security policy defined by the model is applicable to the new device and commissions the new device to comply with any relevant security policies. This mitigates the necessity for a system administrator to manually configure individual devices to comply with plant-wide security policies.

Automatic endpoint security policy assignment by zero-touch enrollment

Techniques to facilitate feature licensing of industrial devices employed in an industrial automation environment are disclosed herein. In at least one implementation, a security certificate for an industrial device is provisioned based on a first private key associated with the industrial device, wherein the first private key is securely stored in a hardware root of trust within the industrial device. A device information package for the industrial device is generated based on the security certificate, wherein the device information package is encrypted with a first public key paired with the first private key and signed by a certificate authority using a second private key. The device information package is provided to the industrial device, wherein the industrial device is configured to validate the device information package using a second public key paired with the second private key and decrypt the device information package with the first private key.

Cryptographic feature licensing

A device may include a communication component that may communicatively couple to a first network. The device may also include a processor that may transmit a first signal via the communication component to a network address translation (NAT) system, the first signal including a first request to discover a server device. The NAT system may communicatively couple to the first network and a second network, such that the first network is inaccessible to the second network. The processor may then receive location data associated with the server device and transmit a second signal addressed to the server device based on the location data. The second signal is transmitted to the NAT system, such that the second signal may include a second request for a security policy from the server device. The processor may then receive the security policy via the NAT system and adjust one or more communication operations based on the security policy.

Securely deploying security policy and configuration through network address translation systems

An industrial security policy configuration system generates and implements security policies for industrial automation systems based on design data for the industrial systems generated by device manufacturers, system integrators, original equipment manufacturers, or the owners of the industrial assets during the design of the industrial systems. the collected design data to a security rule set defining device-level communication privileges. The system translates the collected design data to a security rule set defining device-level communication privileges, which are then translated to a comprehensive set of security policies customized to the requirements of the industrial systems represented by the design data. By leveraging the rich set of available design data to identify or infer security requirements and generate suitable security configurations, the system can mitigate the need to manually configure security policies based on human judgments regarding normal and abnormal network traffic.

Automated discovery of security policy from design data

Techniques to facilitate protecting control data used in an industrial automation environment are disclosed herein. In at least one implementation, an encryption key pair is generated for an industrial controller, wherein the encryption key pair comprises a public key and a private key. The private key is stored within a secure storage system of the industrial controller. Controller program content is then encrypted using the public key to generate encrypted controller content. The encrypted controller content is then provided to the industrial controller, and the industrial controller is configured to decrypt the encrypted controller content using the private key and execute the controller program content.

Device specific cryptographic content protection

A secure method for establishing communications to provision modules in an industrial control system generates a certificate signing request to obtain a signed security certificate. A mobile device is located proximate to the module with the certificate signing request, and the mobile device has previously established itself as a secure communication interface on the network. The mobile device establishes a first connection between the module and the mobile device via a short-range protocol and a s second connection between the mobile device and a signing server via a network. The mobile device retrieves the certificate signing request via the first connection and transmits the certificate signing request to the signing server via the second connection. Because the mobile device has previously established itself as a secure interface, the transmission of the certificate signing request to the signing server may be made via a secure connection.

Method and apparatus for secure device provisioning in an industrial control system

A model-based industrial security policy configuration system implements a plant-wide industrial asset security policy in accordance with security policy definitions provided by a user. The configuration system models the collection of industrial assets for which diverse security policies are to be implemented. An interface allows the user to define security policies for a plant environment at a high-level by grouping the industrial assets into security zones, and defining any additional communication permissions in terms of asset-to-asset, asset-to-zone, or zone-to-zone conduits. Based on the model and these policy definitions, the system generates asset-level security setting instructions configured to set appropriate security settings on one or more of the industrial assets, and deploys these instructions to the appropriate assets in order to implement the defined security policy.
