Verification testing

Cybersecurity tests that cover all hardware and software cybersecurity requirements are necessary to determine if the hardware and software design matches the cybersecurity specifications. Traceability between security requirements and security test cases is an essential step to ensure that the security measures are implemented as intended.

Similarly, formal verification techniques can be employed to verify that a specific hardware module can achieve its security objectives. At the unit level, ISO/SAE 21434 does not make specific process requirements, besides standard unit verification. Following a common quality management system will ensure that software units are tested with the right level of coverage before they’re integrated into larger components. A good practice for unit testing is to apply tests that exercise unit inputs, outputs, data, and control flows. The tests should cover error handling, fault injection, and methods for recovery to ensure...
