The security of embedded systems is important today and even more in the future.

 

Learn how to safely use C/C++ in critical systems, including best practices for memory management, input validation, and error handling. Secure embedded systems combine numerous strategies and procedures for the complete coordination of cyber security in the programming and hardware of embedded frameworks.

You will learn about embedded security and industry standards, including ISO/SAE 214341, IEC 62443, NIST SP 800-53, Common Criteria, and OWASP. You also get an introduction to the RUST programming language and its built-in security features, including Memory-safety and Type-safety.

Training format

  • 3 days online training: 18 hours, 3 sessions, 6 hours each
  • Course dispensed using the Teams video-conferencing system.
