A physical connection is defined as “a connection between electronic information systems or components implemented using physical means, including through electrical, optical or mechanical interfaces, wires or radio waves” (Article 3(9)).
A logical connection is defined as “a virtual representation of a data connection implemented through a software interface” (Article 3(8)).
An indirect connection is defined as “a connection to a device or network, which does not take place directly but rather as part of a larger system that is directly connectable to such device or network” (Article 3(10)).
Under certain conditions, all products with digital elements integrated in or connected to a larger electronic information system can serve as an attack vector for malicious actors. As a result, even hardware and software considered to be less critical can facilitate the initial compromise of a device or network, enabling malicious actors to gain privileged access to a system or to move laterally across systems. Manufacturers should therefore ensure that all products with digital elements are designed and developed in accordance with the essential cybersecurity requirements laid down in this Regulation. That obligation relates to both products that can be connected physically via hardware interfaces and products that are connected logically, such as via network sockets, pipes, files, application programming interfaces or any other types of software interface. As cyber threats can propagate through various products with digital elements before reaching a certain target, for example by chaining together multiple vulnerability exploits, manufacturers should also ensure the cybersecurity of products with digital elements that are only indirectly connected to other devices or networks (Recital 9).
A physical connection can be direct, for example, when a product with digital elements connects via a USB cable (e.g. a printer connecting to a laptop); via an Ethernet cable (e.g. a PC connecting to a router); via a fibre optic cable (e.g. a fibre-optic router connecting to the internet service provider’s network) or a copper cable (e.g. an industrial fieldbus such as PROFIBUS connecting a sensor to a programmable logic controller); via radio waves, such as via Wi-Fi (e.g. a point-of-sale (POS) terminal that connects to a shop’s network), Bluetooth (e.g. a Bluetooth headset connecting to a smartphone), near-field communication technology (e.g. a door lock connecting to an NFC tag).
A logical connection can be direct, for example, when a product with digital elements initiates or manages communication with other devices or networks (e.g. a browser establishing an HTTPS session to access a website, or an email client initiating an IMAP or SMTP exchange); or it can be indirect, when a product with digital elements does not itself initiate the communication but runs on a host system that does (e.g. an offline text editor or a calculator that are indirectly connected via the operating system).
Products with digital elements can simultaneously have more than one form of data connection to other devices or networks.
On the other hand, a product with digital elements does not have a direct or indirect data connection when its intended purpose or reasonably foreseeable use do not include such connection to other devices or networks. Some examples of products that would not fall in scope of the CRA include:
- a dishwasher with embedded firmware controlling dishwashing cycles, but with no capability to connect to other devices or networks;
- a basic calculator with embedded firmware performing arithmetic operations, but with no capability to connect to other devices or networks;
- an electronic toy with embedded firmware playing pre-recorded light and sound effects, but with no capability to connect to other devices or networks;
- a coffee machine with embedded firmware that sets brew times or coffee strength via a control panel, but with no capability to connect to other devices or networks
- an electric toothbrush with a wireless charging station, but with no capability to connect to other devices or networks.
