IEC 81001-5-1 Cybersecurity Readiness & Risk Assessment | Medical Device Software Compliance in United States

Overview

In the United States, medical device software is increasingly connected, cloud-enabled, and integrated with hospital IT networks. From Software as a Medical Device (SaMD) to embedded device software and remote monitoring platforms, cybersecurity has become a critical patient safety and regulatory requirement. Cyber threats targeting medical devices can lead to data breaches, device malfunction, patient harm, and regulatory action.

IEC 81001-5-1 provides internationally recognised guidance for cybersecurity risk management of health and medical device software throughout the product lifecycle. It complements U.S. regulatory expectations by emphasizing secure design, development, testing, deployment, and post-market maintenance.

Cyberintelsys, a CREST-accredited cybersecurity company, delivers cybersecurity readiness and risk assessment services aligned with IEC 81001-5-1 to support medical device software compliance across the United States.

Importance of Cybersecurity Readiness for Medical Device Software

Medical device software is a high-value target due to patient safety impact, sensitive health data, and strict regulatory oversight. Common cybersecurity risks include:

  • Insecure authentication and access control in device software and companion applications

  • Vulnerabilities in wireless, Bluetooth, and network communication protocols

  • Insecure APIs and cloud backends supporting connected devices

  • Weak encryption, key management, and firmware protection

  • Supply chain risks and vulnerable third-party components

Cybersecurity readiness and risk assessment are essential to:

  • Identify and mitigate cybersecurity risks throughout the device lifecycle

  • Align with IEC 81001-5-1 risk management expectations

  • Support U.S. FDA cybersecurity requirements and premarket submissions

  • Protect patient safety, device functionality, and data integrity

  • Demonstrate due diligence to regulators, healthcare providers, and partners

Cyberintelsys CREST-Accredited Risk Assessment Approach

Cyberintelsys follows a structured, risk-based methodology aligned with CREST standards and international compliance frameworks such as IEC 81001-5-1, IEC 60601, and IEC 62443.

1. Scope Definition & Asset Identification

  • Identify medical device software components including embedded firmware, companion mobile apps, web portals, APIs, and cloud services

  • Map device connectivity, data flows, trust boundaries, and safety-critical functions

  • Define controlled assessment boundaries to ensure patient safety and regulatory compliance

Deliverables: Scope document, software asset inventory, and risk assessment plan

2. Cybersecurity Risk Assessment

  • Identification of threats, vulnerabilities, and attack surfaces affecting device software

  • Threat modelling using STRIDE and MITRE ATT&CK for ICS

  • Assessment of security controls protecting device integrity, availability, and confidentiality

  • Evaluation of third-party libraries, operating systems, and supply chain components

Output: Risk register with likelihood, impact, and risk ratings mapped to patient safety

3. Vulnerability Assessment & Penetration Testing

  • Secure testing of medical device software, APIs, and supporting infrastructure

  • Simulation of real-world attack scenarios targeting device communication and control paths

  • Validation of encryption, authentication, firmware update mechanisms, and access controls

Deliverable: Technical findings report with proof-of-concept evidence and remediation guidance

4. Risk Prioritisation & Mitigation Planning

  • Prioritise risks based on exploitability, safety impact, and regulatory relevance

  • Develop remediation and risk treatment plans aligned with IEC 81001-5-1 principles

5. Compliance Reporting & Documentation

6. Validation & Ongoing Readiness

  • Reassessment after remediation to confirm risk reduction

  • Support for post-market cybersecurity monitoring and continuous improvement

Methodology Overview

  1. Architecture Review: Analyse medical device software architecture and connectivity

  2. Threat Modelling: Identify attack paths using STRIDE and MITRE ATT&CK for ICS

  3. Risk Evaluation: Assess likelihood and impact on safety, effectiveness, and compliance

  4. Technical Testing: Validate security controls through targeted testing

  5. Reporting: Deliver regulator-ready cybersecurity risk documentation
