Introduction

MRI and CT Scanners are critical diagnostic systems used across healthcare facilities in South Africa to deliver accurate imaging and support clinical decision-making. These devices rely on sophisticated software, embedded systems, and network connectivity to process high volumes of sensitive patient data in real time.

As healthcare environments become more digitized, MRI and CT Scanners are increasingly connected to hospital information systems, cloud platforms, and remote diagnostic services. This connectivity enhances efficiency but also introduces cybersecurity risks that can impact patient safety, data confidentiality, and device availability.

Cyberintelsys supports healthcare providers and medical device manufacturers in securing MRI and CT Scanners through structured security testing aligned with EU MDR and FDA 510(k). The focus remains on ensuring regulatory compliance while maintaining the integrity and reliability of diagnostic systems.

Regulation: EU MDR and FDA 510(k) Requirements

Medical imaging devices must comply with strict regulatory requirements to ensure safety, performance, and cybersecurity.

1.EU MDR (Medical Device Regulation)

Security testing aligned with EU MDR focuses on:

1. Risk management based on ISO 14971
2. Secure software lifecycle practices
3. Protection against unauthorized access and cyber threats
4. Validation of device safety and performance
5. Continuous monitoring through post-market surveillance

2.FDA 510(k) Cybersecurity Requirements

Security testing aligned with FDA expectations includes:

1. Pre-market cybersecurity risk assessments and documentation
2. Threat modeling and vulnerability identification
3. Secure design and development validation
4. Software Bill of Materials (SBOM) verification
5. Post-market monitoring and incident response readiness

3.Alignment with Global Frameworks

Cyberintelsys follows globally recognized standards to ensure comprehensive security:

1. ISO/IEC 27001 for information security management
2. ISO 14971 for medical device risk management
3. IEC 62304 for medical device software lifecycle
4. IEC 81001-5-1 for health software cybersecurity
5. NIST Cybersecurity Framework (NIST CSF)
6. OWASP Top 10 for application security risks
7. MITRE ATT&CK for threat modeling

Importance of Security Testing for MRI / CT Scanners

Cybersecurity risks in imaging systems can directly impact clinical operations and patient outcomes. Structured security testing helps mitigate these risks effectively.
