As technology advances, so do the risks associated with it. The need for Intrusion Detection Systems (IDS) in modern embedded systems applications is becoming increasingly crucial. This threat is especially true in fields such as the automotive industry, where products are more connected than ever. These systems require a high level of resiliency to external attacks. That is where IDS comes in. By serving as the first line of defense, IDS helps to identify any alterations in software's nominal behavior that could lead to harm. It is essential in ensuring the safety and security of modern embedded systems. This study proposes a new approach to developing an IDS that classifies running software based on Hardware Performance Counters (HPC).
