Intrusion Detection System (IDS)
Security system that monitors vehicle networks for unauthorized or abnormal activities.

An IDS continuously analyzes in-vehicle communication to detect cyberattacks or anomalies. It uses signature-based or behavioral models to flag suspicious patterns in CAN or Ethernet traffic. When threats are detected, alerts are generated, or the system enters a safe mode. IDS is a key element in automotive cybersecurity frameworks like ISO/SAE 21434. As cars become more connected, proactive detection protects both safety and privacy.
