External interfaces

Every external interface represents a potential attack surface. The integrator and end user must control access to Asycube’s physical connections.

• Ethernet communication: Connect the RJ45 communication interface only to the devices that control Asycube. Do not connect this interface to an IT network or the public internet.

• Electrical connections: Follow the electrical integration instructions, including the power connection requirements. Restrict access to the connectors and cabling to authorized persons. Proper shielding, grounding, and physical security reduce the risk of tampering.

• IP address recovery controls: Where available, restrict access to the selectors or reset control used for IP address recovery to authorized persons, as they allow the network settings to be reset.

• Programming connection: The RJ12 programming connection on Asycube 380/530 is reserved for Asyril internal use, as described in Electrical interfaces.

Cybersecurity

The Asycube Ethernet port must only be connected to the devices that control it, with no connection to an IT network. Ensure that Asycube can only be accessed by authorized persons.
