Abstract

As cyber threats continue to evolve, organizations in the U.S. and Canada are increasingly at risk of data breaches, system disruptions, and financial losses. This paper proposes a holistic cyber risk assessment model designed to identify, evaluate, and mitigate cyber threats in enterprises across these regions. The model integrates a comprehensive approach, combining both technical and organizational factors to ensure a robust defense against cyber risks. By incorporating industry best practices, regulatory requirements, and emerging threat landscapes, this model aims to enhance the security posture of organizations in critical sectors such as healthcare, finance, and manufacturing. The model emphasizes a multi-layered risk assessment process that includes threat identification, vulnerability analysis, risk evaluation, and the development of mitigation strategies. It considers both internal and external risk factors, including the potential impact of third-party relationships, regulatory compliance obligations, and emerging technologies such as AI and IoT. The framework provides a detailed methodology for assessing risks in a dynamic threat environment, enabling organizations to stay ahead of evolving cyber risks. Key components of the model include the identification of potential cyber threats (e.g., phishing, ransomware, insider threats), vulnerability assessment through penetration testing and security audits, and the use of risk metrics to prioritize threats based on their potential impact and likelihood. The model also includes the development of response strategies, such as incident response plans, disaster recovery protocols, and continuous monitoring processes to ensure real-time threat detection and mitigation. The paper highlights the importance of integrating this model with existing cybersecurity frameworks, such as NIST and ISO 27001, to maintain alignment with regulatory standards and industry best practices. By adopting this holistic risk assessment model, organizations in the U.S. and Canada can proactively manage cyber threats, enhance their cybersecurity strategies, and ensure the protection of sensitive data and critical systems.
