The case study centers around CyberHealth Security, a cybersecurity consultancy hired to assess the digital security of MedTechPro Hospital (MTPH).

As a technologically advanced healthcare institution, MTPH relies heavily on:

• electronic health records (EHRs)
• internal communication systems
• IoT-enabled medical devices

The goal of CyberHealth is to conduct structured penetration testing using Penetration Testing Execution Standard (PTES).

PTES Phases

• Pre-engagement interactions: Planning the test scope, goals, and ethical boundaries. Black box, white box, and grey box testing approaches are evaluated.
• Intelligence gathering: Using OSINT to collect public data on MTPH, including employee info, network topologies, and exposed systems.
• Threat modelling: Identifying potential attackers and evaluating their capabilities and intentions. Key digital assets like EHRs are prioritized.
• Vulnerability analysis: Automated and manual scans uncover system weaknesses and assess their risk levels.
• Exploitation: Testing real-world attacks such as SQL injection, cross-site scripting, and buffer overflow to gauge system resilience.
• Post-exploitation: Evaluating data access, privilege escalation, persistence, and forensic traces to understand breach implications.
• Reporting: Delivering a comprehensive report with findings, impacts, and prioritized security recommendations.

Ethical and Operational Challenges

The case study emphasizes ethical responsibility, especially in a healthcare setting. Testers must:

• Obtain proper authorization
• Ensure data confidentiality and integrity
• Avoid disrupting hospital services
• Deliver actionable and transparent reporting

Operational challenges include selecting suitable testing approaches, conducting safe reconnaissance, and planning incident response strategies.
