Which correctly describes the difference between the automotive standards ISO 26262 and ISO/SAE 21434?

Answer: A. ISO 26262 addresses hazards caused by component failures and design errors, while ISO/SAE 21434 addresses protection against threats from malicious attacks (cyberattacks)

ISO 26262 is a functional safety standard for preventing hazards caused by random hardware failures and systematic failures, evaluating risk through HARA. ISO/SAE 21434 is a cybersecurity standard for protecting vehicles from intentional attacks such as hijacking communications or tampering with software, evaluated through threat analysis and risk assessment (TARA). Their scopes differ, but if an attack disables safety mechanisms, safety is also compromised, so the two activities are carried out in coordination.
