What are the benefits of SAE J3061?

The SAE J3061 standard provides a framework for managing cybersecurity risks throughout the product lifecycle. This includes specifying requirements for the design, development, production, and operation phases. In addition, the standard defines processes and tools that can be used to assess compliance. The standard is also designed to be compatible with other SAE standards, such as SAE J3034, which provides guidance on data security for automotive networks.

The SAE J3061 standard offers a number of benefits for companies developing cyber-physical vehicle systems:

• It provides a comprehensive and systematic approach to managing cybersecurity risks
• It is based on existing standards and best practices in the field of security engineering
• It is compatible with other SAE standards, such as SAE J3034
• It defines processes and tools that can be used to assess compliance with the standard.

Relationship between SAE J3061 and ISO 26262:

SAE J3061 is based on the ISO 26262 standard and includes specific requirements for automotive systems. SAE International released SAE J3061 in order to provide guidance specifically for vehicles with cyber-physical systems.

SAE J3061 is complementary to ISO 26262 in that it provides guidance on best development practices from a cybersecurity standpoint (threats), as well as ISO 26262’s best development methods to avoid functional danger (hazards). SAE J3061 also requires a similar sound development approach and follows the same phases of growth as ISO 26262.

In practice, when J3061 is used in a development team that is already adhering to ISO 26262, the procedures are such that they may be integrated at each stage of the product lifecycle – with the exception that only one test team is utilized for both safety and cybersecurity activities in even the most rudimentary projects. While neither document commands their use, their usage is nearly essential in all but the simplest endeavors. However, while the documents complement each other, they were developed independently and as such there are some notable differences.

What are the SAE J3061 compliance tools?

The SAE J3061 standard provides a framework for managing cybersecurity risks throughout the product lifecycle. This includes specifying requirements for the design, development, production, and operation phases. In addition, the standard defines processes and tools that can be used to assess compliance. Some of these compliance tools are:

• SAE’s Cybersecurity Assurance Program (CAP) – CAP is a voluntary program that assesses how well a company’s cybersecurity processes meet SAE J3061.
• SAE’s Global Cybersecurity Management System (GCMS) – GCMS is a software platform that helps companies manage their cybersecurity risks and compliance with SAE J3061.
• SAE’s Automotive Cybersecurity Health Index (ACHI) – ACHI is a tool that helps companies measure and improve their automotive cybersecurity posture.
• SAE’s Automotive Information Sharing and Analysis Center (Auto-ISAC) – Auto-ISAC is an information sharing and analysis center for the automotive industry.

What are SAE J3061 certifications?

SAE J3061 does not currently have any certification programs. However, SAE International offers other certification programs that may be relevant to users of the standard, such as:

• SAE’s Cybersecurity Expert (CYSE) program
• SAE’s Certified Automotive Cybersecurity Professional (CACP) program

The CYSE program is a global certification program that assesses an individual’s knowledge of SAE J3061. The CACP program is a professional certification program that recognizes individuals who have demonstrated proficiency in automotive cybersecurity.

Both the CYSE and CACP programs are administered by SAE International.
