The proposed system presents a comprehensive framework for enhancing automotive cybersecurity by synergizing IoT components, advanced machine learning techniques, and cloud infrastructure. The workflow encompasses various stages to ensure the overall safety and security of connected vehicles. The system begins with an advanced accident detection mechanism, leveraging IoT components such as bump switches, buzzers, ESP32 modules, switches, device sensors, and a printed circuit board (PCB). These components collectively form a robust network that constantly monitors the vehicle's surroundings for collision events. Upon detecting an accident, the system triggers immediate notifications via the cybersecurity hardware, alerting relevant parties such as emergency services and vehicle owners. This rapid response capability aims to minimize the consequences of accidents and ensure prompt assistance. A pivotal aspect of the proposed system is its application of machine learning algorithms, namely K-Means and Support Vector Machine (SVM) for cyber attack classification. These algorithms are trained on labelled datasets, enabling them to discern patterns associated with various types of cyber threats. As new data arrives, the algorithms rapidly categorize and classify potential cyber attacks, providing insights into the nature and potential severity of each threat. This proactive identification empowers the system to take swift countermeasures, thereby bolstering the vehicle's overall cybersecurity.  K-means is a widely used clustering algorithm in machine learning and data analysis. It aims to partition a dataset into distinct groups, or clusters, based on similarity of data points. The algorithm iteratively assigns each data point to the nearest cluster centroid and recalculates centroids based on the mean of the points within each cluster. This process continues until centroids stabilize, yielding well-defined clusters. K-means is efficient and intuitive, making it valuable for tasks like grouping data, pattern recognition, and even in our automotive cybersecurity proposed work, where it aids in classifying and categorizing potential cyber security attacks based on their characteristics.  Support Vector Machine (SVM) is a powerful machine learning algorithm used for classification and regression tasks. SVM aims to find a hyperplane that best separates data points belonging to different classes in a high-dimensional space. It identifies a decision boundary with the maximum margin between classes, enhancing its ability to generalize to new, unseen data. SVM can handle both linear and non-linear data by using kernel functions to transform the data into a higher-dimensional space. This algorithm is particularly useful in our automotive cybersecurity proposed work, where SVM assists in accurately classifying cyber security attacks based on their distinct features, contributing to a more secure and resilient vehicle system.  Moreover, the system is fortified with theft prevention capabilities. By integrating IoT components like switches and sensors, the system can detect unauthorized tampering or theft of vehicle parts. When such incidents occur, the system promptly generates notifications, alerting stakeholders and enabling swift action to mitigate further risks. The combination of real-time theft prevention and immediate notifications contributes significantly to overall vehicle security. To facilitate seamless operations and data accessibility, the system utilizes cloud-based storage infrastructure. Incident data, including accident reports and information about detected cyber threats, are securely stored in the cloud. This repository of information ensures that stakeholders can analyze incidents, coordinate responses, and implement preventive measures effectively.
