+# Threat Modeling: HealthGuard 360
+
+## Application Summary
+
+HealthGuard 360 is a comprehensive healthcare management system that integrates patient data, appointment scheduling, and secure messaging. It aims to improve patient care by providing healthcare professionals with easy access to patient information and enabling efficient communication.
+
+## Threat Scenarios
+
+| Scenario | Description | Impact | Mitigation |
+|----------|-------------|--------|------------|
+| AI-Generated External Phishing Email Utilizing Admin Credentials | An attacker uses AI to craft a sophisticated phishing email targeting admin users to steal their credentials. | Unauthorized access to sensitive patient data and administrative functions. | Implement multi-factor authentication (MFA) and conduct regular phishing awareness training for staff. |
+| Attack Against Machine Processes and the Data Lake | An attacker targets machine processes and the data lake to manipulate or steal large volumes of patient data. | Data breaches and potential manipulation of patient records. | Implement strict access controls, monitor data access patterns, and use encryption for data at rest and in transit. |
+| SQL Injection Attack | An attacker exploits a vulnerability in the application's input fields to execute malicious SQL commands. | Unauthorized access to the database, leading to data breaches. | Use parameterized queries and conduct regular security audits to identify and fix vulnerabilities. |
+| Insider Attack Taking Quant Algorithms | A disgruntled employee with access to the system misuses their privileges to steal or manipulate proprietary algorithms. | Loss of intellectual property and potential competitive disadvantage. | Implement strict access controls, monitor user activities, and conduct regular security training. |
+| Ransomware Attack | An attacker deploys ransomware to encrypt patient records and demands a ransom for decryption. | Disruption of healthcare services and potential loss of critical patient data. | Regularly back up data, use endpoint protection solutions, and educate staff on recognizing ransomware threats. |
+
+## Risks Summary
+
+### High Risks:
+1. Phishing attacks leading to credential theft
+2. SQL injection vulnerabilities
+3. Insider threats from employees with access to sensitive data
+4. Ransomware attacks disrupting services
+
+### Medium Risks:
+1. Social engineering attacks targeting non-admin staff
+
+## Controls Required
+
+1. Regular Security Audits: Conduct audits using the Application Security Verification Standard (ASVS) to detect vulnerabilities in HealthGuard 360.
+2. Patch Management: Ensure all software components are up-to-date to protect against known vulnerabilities.
+3. Phishing Awareness Training: Educate staff on identifying and reporting phishing attempts.
+4. Web Application Firewall (WAF): Deploy a WAF to monitor and filter incoming traffic for malicious activity.
+5. Data Backup and Recovery: Implement a robust backup and recovery plan to mitigate the impact of ransomware attacks.
+6. Multi-factor Authentication (MFA): Enhance authentication security to prevent unauthorized access.
+7. Strict Access Controls: Implement role-based access control (RBAC) to limit access to sensitive data based on user roles and permissions.
+8. Continuous Monitoring: Monitor user activities and data access patterns to detect suspicious behavior.
+
+## Methodology
+
+All scenarios were run against the cyber attack kill chain, utilizing the MITRE ATT&CK framework and STRIDE for control gap assessments to identify and mitigate potential threats effectively.
