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.
