This standard identifies the main assets and threats targeting operating systems used in connected vehicles. This standard defines the security requirements of the operating systems to support the core security functions in connected vehicles. This standard also establishes test methods to evaluate the security of operating systems in connected vehicles. This standard addresses the security challenges and attack scenarios related to the operating system in connected vehicles. The objective of this standard is to provide security requirements and testing methods to facilitate the design, implementation, and security assessment of the operating system. New IEEE Standard - Active. The main assets and threats targeting operating systems used in connected vehicles are identified. The security requirements of the operating systems to support the core security functions in connected vehicles are defined. A set of test methods is established to evaluate the security of operating systems in connected vehicles.
