Threat Modeling A new medium-sized health care facility just opened and you are hired as the CIO. The CEO is somewhat technical and has tasked you with creating a threat model. The CEO needs to decide from 3 selected models but needs your recommendation. Review this week’s readings, conduct your own research, then choose a model to recommend with proper justifications. Items to include (at a minimum) are: You will research several threat models as it applies to the health care industry, summarize three models and choose one as a recommendation to the CEO in a summary with a model using UML Diagrams (Do not copy and paste images from the Internet). In your research paper, be sure to discuss the security risks and assign a label of low, medium or high risks and the CEO will make the determination to accept the risks or mitigate them. Your paper should meet the following requirements: Purchase the answer to view it

Threat modeling is a crucial process in the field of cybersecurity, as it helps organizations identify potential security risks and develop a roadmap for mitigating those risks. In the case of the newly opened medium-sized health care facility, the CEO has requested a threat model recommendation from the CIO. This paper will delve into the research and analysis of three selected threat models in the context of the health care industry, and provide a justified recommendation for the CEO.

The first model under consideration is the STRIDE model, which stands for Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege. This model, developed by Microsoft, focuses on the identification and analysis of potential threats in these six categories. Spoofing refers to the act of impersonating a user or system, while tampering involves unauthorized modification of data or systems. Repudiation deals with the denial of a user’s involvement in an action, and information disclosure relates to the unauthorized access or exposure of sensitive information. Denial of service refers to an attack that renders a system or service unavailable, and elevation of privilege concerns the unauthorized elevation of user privileges. By analyzing these categories of threats, the STRIDE model provides a comprehensive framework for identifying and prioritizing security risks.

The second model to consider is the OCTAVE Allegro model. This model, developed by Carnegie Mellon University, focuses on risk assessment and management. It involves a systematic process of identifying assets, threats, vulnerabilities, and impacts, and then assessing the associated risks. The OCTAVE Allegro model emphasizes the importance of involving both technical and non-technical stakeholders in the threat modeling process. By incorporating diverse perspectives, this model ensures a more holistic understanding of the security risks facing an organization.

The third model under consideration is the DREAD model, which stands for Damage potential, Reproducibility, Exploitability, Affected users, and Discoverability. This model, developed by Microsoft, provides a quantitative approach to threat modeling. Each attribute in the DREAD model is assigned a score ranging from 0 to 10, with 10 indicating the highest potential risk. By quantifying each attribute, the DREAD model allows for a more precise assessment and comparison of security risks.

After careful consideration and analysis, the recommended threat model for the CEO is the STRIDE model. This model provides a comprehensive framework for identifying and analyzing potential threats in the health care industry. It encompasses a wide range of threats and prioritizes them based on their potential impact. By utilizing the STRIDE model, the health care facility can effectively focus its resources on mitigating the most critical security risks.

In terms of security risks, it is essential to assign a label of low, medium, or high to each threat identified. The CEO will ultimately make the determination of whether to accept the risks or take measures to mitigate them. The recommendation is to assign security risk labels based on the potential impact of each threat on the confidentiality, integrity, and availability of the health care facility’s data and systems. This approach will help prioritize efforts to address the most significant security risks, ensuring the protection of sensitive patient information and the uninterrupted delivery of health care services.
