Cybersecurity is the set of practices, technologies, and processes designed to protect computer systems, networks, data, and users from attacks, intrusions, damage, or unauthorized access.

It aims to ensure the confidentiality, integrity, and availability of digital information by preventing hacking, viruses, ransomware, or any form of cyberattack.

Cybersecurity serves to protect data and digital infrastructures to ensure their proper functioning and the safety of users.

Embedded cybersecurity aims to protect integrated computer devices within specialized objects, such as cars and medical equipment, from attacks and intrusions. These systems present unique challenges due to their limited resources and the need to operate in real-time, making their protection particularly complex.

To ensure the security of these systems, it is essential to implement secure development methodologies, such as “Security by Design,” secure manufacturing, lifecycle management, and automated testing. Protecting data and communications is also crucial, which involves mastering the “science of secrecy” and using techniques like encryption, secure communication protocols, and provisioning.

It is therefore important to harden these systems against attacks using robust solutions such as secure enclaves, “secure boot,” and hardware hardening. The overall goal is to ensure the confidentiality, integrity, and availability of data while ensuring safe and reliable operation in sensitive sectors like automotive and healthcare. Adapted techniques, such as lightweight encryption, enhanced authentication, intrusion detection, and secure updates, are used to achieve this goal.
