Cybersecurity
"
A new level of cybersecurity testing goes beyond the vehicle itself and
extends to the entire network.

vulnerable to cyberattacks lies on the individual stakeholders.
Unfortunately, most are conducting verification
in silos. It is particularly challenging on the network
side, as there is no established process for an end-to-end
verification from the Central Unit (CU) to Distributed
Units (DU) and Radio Units (RU), as well as controlling
network slices connected to specific use cases.
A potential solution is the establishment of cybersecurity
plugfests. Manufacturers of base stations, CUs,
DUs, RUs and test companies, as well as software developers
can conduct scenarios to determine how well an
entire network can withstand cyberattacks, not just the
individual elements. It is particularly important given
the multiple mission-critical use cases of vehicles.
Establishing test environments
To further ensure systems can withstand cyberattacks
efficiently, test environments that can simulate realworld
scenarios in a controlled setting need to be

created. These tests should be done by Tier 1 suppliers
to ensure their specific network components meet
specification. Second-level testing based upon the use
case also needs to be conducted at the system level.
Common test hardware is critical so that different
software applications can be loaded. It is also important
that a single vendor provides this software-centric
solution that can conduct cybersecurity, as well as RF
and application tests. Cybersecurity elements sit atop
the RF and application layers, so a software solution
that can test all layers creates efficiencies that improve
design confidence and lowers cost-of-test.
A software-based solution has another advantage.
Most Tier 1 suppliers work with multiple auto
manufacturers. Software allows for a seamless and
efficient testing environment that is flexible and can
be enhanced to meet specific requirements.
Support of legacy wireless technologies is another
consideration. Vehicles will continue to utilize 3G, 4G
