Ways Cybersecurity Aspects Address Threat Modeling

Auto Tech Outlook | Tuesday, August 02, 2022

Threat modeling provides information on potential threats, vulnerabilities, and weaknesses in cybersecurity.

FREMONT, CA: Risk assessment and threat analysis in automotive evaluates the risk posed by potential cybersecurity threats to the system under consideration (SUC) and identifies them. The process is an essential component of the cybersecurity development lifecycle in the automotive industry, thanks to the new rules and requirements. Cyber threats can impact entire enterprises, areas, or crucial infrastructure sectors. In other words, cyber dangers might appear at different system levels and affect a range of system attributes and functions. The threat modeling approach can give information in various ways to identify potential threats, vulnerabilities, and cybersecurity weaknesses.

Risk management 

It is critical to understand that threat modeling is part of several activities related to risk management. These activities include framing risks, analyzing them, assessing them, and evaluating their responses. The risk management process for enterprises and projects is typically integrated with these activities. A comprehensive risk management system also considers non-adversarial threats (for example, hazards to systems from the perspective of functional safety); however, in this study, the main focus is on adversarial threat models.

Systems engineering security

Threat modeling is utilized for requirements engineering, system analysis, design, implementation, testing, and operations and maintenance throughout the system development lifecycle. When recognized threat scenarios and attack scenarios are used to guide system design, the choice of mitigation measures, as well as the testing of these measures, threat modeling is particularly crucial for design analysis and testing. The threat modeling process is modified to reflect particular system features, functions, and layers at different levels of granularity. This work customizes the threat modeling process for automotive system security engineering.

Foraging and profiling technology

By assessing and contrasting the capabilities of technology, goods, and services, threat modeling aids in discovering threat scenarios and assault routes. This comparison makes it possible to characterize technologies for effective threat mitigation, identify research and technological gaps, and scout out solutions that may be of interest.

Operations and analysis

Threat modeling can aid in the search for signs or proof of adversary activity to direct ongoing security analysis and monitoring, speeding up the creation and introduction of defense measures into the operational environment such as DevOps.
