Know what ISO 21434 is and learn measures that you can take to prepare for it and be compliant.
Knowing ISO 21434
ISO 21434 assists automotive product developers, OEMs, and suppliers in ensuring vehicle security. As automobiles become more networked and autonomous vehicles become more common, it is crucial that automotive software be designed and executed with security in mind.
How to be Compliant with ISO 21434
SELECT THE CORRECT LANGUAGE
When picking a programming language to meet the ISO 21434 security criteria, keep security issues in mind. A secure language has unambiguous syntax and 2 semantic definitions as well as secure design and coding techniques.
CERTIFIED PROFESSIONALS
ISO 21434 is a document that focuses on the security of automotive software. As with any software, it will be most secure when designed and implemented by experts. Ensure that the ISO 21434 experts that you choose have been certified by a reputable accreditation organization.
PROTECT THE ECU
The most important part of ensuring a secure system is protecting the integrity of the ECU. This means that you must prevent illegal physical access to the ECU. And you must ensure that all communication between the ECU and external devices is with encryption or authentication.
This also means that you must protect all communication paths between systems in the vehicle, such as communication between 2 ECUs, communication between different systems in a single ECU, communication from one ECU to an I/O device, or communication from an I/O device to another I/O device.
USE REGULAR SOFTWARE TESTING TOOLS TO PREVENT VULNERABILITIES
All software has vulnerabilities, but if you can find these vulnerabilities early enough during the development process. You can fix them before they lead to security issues. Use regular software testing tools to find these vulnerabilities before they lead to security issues.
IMPLEMENT A SOFTWARE DEVELOPMENT LIFE CYCLE
The software development life cycle is a set of steps that takes to create software. It includes the software design process, the coding process, testing processes, and documentation processes. All of these processes are necessary in order to create secure software.
Secure Design
Design your software using secure design techniques. Identify security risks early during the design process and implement security measures to mitigate them. It is also important to remember that secure design must be throughout the life cycle of the software, not just at the beginning. Secure Design techniques include:
Secure Coding
Coding your software securely means following secure coding principles and adhering to secure coding practices. Review coding for adherence to secure coding principles by an independent party before being releasing it into production. There are also tools that you can use to ensure that you follow secure coding principles during development. It is important that all developers be trained in secure coding practices through ongoing education programs.
Secure Testing
Testing your software should be done in a way that ensures security vulnerabilities are found as early as possible during development so they can be fixed before they lead to security issues. This means that testers should have expertise in both testing and security so they can find vulnerabilities in your code before you release it into production. Testing should be done for each phase of the life cycle, including design, implementation, integration testing, system testing, acceptance testing, and regression testing.
