Physical Security of the Device

The following are the important physical security points to keep in mind for installing the device:

• Recommend to deploy and use the switching equipment in accordance with a defense-in-depth approach recommended by Schneider Electronic to reduce the risk of switching equipment being attacked.

• Install the ATSE in a cabinet secured in an appropriate manner, for example with a padlock or a key, to avoid risks during installation or the risk of unauthorized physical access.

• I/O accessories (if any) shall be securely deployed to prevent unauthorized access to mitigate the risk of changing the switch settings for the predefined application in use.

• For Modbus-RTU accessories (if any) which is recognized as a security risk in the industry, physical security measures (such as dedicated pipes) are recommended to protect communication cables from unauthorized access, communication drops, data leakage and tampering, etc.

• For the HMI (if any), a lead seal shall be used to prevent unauthorized access to buttons or rotary switches.

• For the independent HMI (if any), it is highly recommended to deploy it with the ATSE in the same cabinet to ensure CANopen communication security, or to protect the communication cables with physical security measures (such as dedicated pipes).
