Overview
Standard Reference: ISO/TS 11633-1:2019 - Health informatics - Information security management for remote maintenance of medical devices and medical information systems - Part 1: Requirements and risk analysis
This technical specification defines the risk assessment and security requirements for Remote Maintenance Services (RMS) provided by vendors to Healthcare Facilities (HCFs). It addresses the special characteristics of healthcare - patient safety, privacy of personal health data, regulatory obligations - and provides practical examples and use cases to guide risk analysis and selection of security controls to protect information assets and medical devices.
Key Topics
- Risk assessment framework for RMS: identification, analysis and evaluation tailored to healthcare information systems and medical devices.
- RMS architectures considered: HCF internal network, external network to Remote Service Centre (RSC), and RSC internal network.
- Connection types & controls:
- RMS over Public Switched Telephone Network (dial-up): caller ID/callback, one-time passwords, audit logs.
- RMS over Internet: firewalls, anti‑malware, VPN encryption, multi‑factor authentication, digital certificates.
- Security requirement categories:
- Technical measures (access control, logging, encryption).
- Operational measures (incident response, secure operations, mobile access controls).
- Contractual measures (HCF–RSC contracts, responsibilities, confidentiality, availability).
- Protection of personal health information (PHI): measures and responsibilities to meet privacy and regulatory obligations.
- Roles & responsibilities: clear delineation of HCF oversight and RMS provider implementation responsibilities.
- Supporting material: Annexes containing RMS use cases, example risk analysis results and risk criteria.
Applications and Who Should Use It
ISO/TS 11633-1:2019 is practical for:
- Medical device manufacturers and RMS providers designing secure remote maintenance solutions.
- Healthcare IT/security teams evaluating RMS contracts, performing risk assessments and oversight.
- Compliance officers and procurement teams requiring documented security assurances from vendors.
- Risk assessors and auditors needing healthcare-specific examples and analysis criteria.
Practical benefits include reduced downtime via secure RMS, documented justification of controls for regulators, consistent security across multiple sites, and economically efficient countermeasure selection.
