  1. Efficiency and security of the Norwegian National Health Network Beijing, April 2010 Janicke Weum Halvor Bjørnsrud Office of the Auditor General of Norway

  2. Content • Background information • Methodological approach • Adopted process of investigation • Preliminary findings • Lessons learned

  3. Helse Nord Svalbard Helse Midt-Norge Helse Vest Helse Sør-Øst Background • The Norwegian National Health Network • technical infrastructure for electronic interchange of individual health data • a main ICT-policy instrument in achieving superior political objectives on health-IT

  4. Figure: The National Health Network

  5. Background • The Network is operated by the public owned enterprise Norwegian Health Net (NHN) • NHN • established in 2004 • shall provide for an adequate technical infrastructure which allows for efficient and secure electronically communication among main health partners

  6. Background • Main health partners are e.g.: hospitals, general practitioners (GP's), medical specialists, municipalities, laboratories, pharmacies and the National Social Security Agency • National goal: by 2012, all main health partners are to be connected to the National Health Network • Connected users by the end of 2009: app. 2050

  7. Why investigate? • Health data • defined as sensitive information • national infrastructure must be in accordance with legislation and expectations concerning information security • requires a sufficient Information Security Management System (ISMS) for operating the Network • responsibility of NHN • Risk • incidents demonstrate defects in the ISMS, e.g. September 2008. • Indicates that privacy and protection measures may not be consistently and effectively built into the ISMS • Objective of investigation • investigate the efficiency and security of the ISMS for operating the National Health Network

  8. How to investigate? • Methods • specific risk-analysis and document analysis • interviews • on-site inspections • Measurement tools • national legislation and regulation • international standards and frameworks such as ISO / IEC 27001, ISO / IEC 27002, COBIT and ITIL

  9. Adoptedprocess • Included ICT-audit expertise in the project team • Obtained basic documentation on the ISMS • Performed analysis on risks to the ISMS in relation to the National Health Network • Obtained additional documentation from the NHN

  10. Adopted process • Defined 8 topics of focus • assessment of risk- and security • training of clients on information security • monitoring of activity in the Network • handling of derogations and security incidents in the Network • handling of planned changes in the different services accessible to clients • encryption of individual health data • handling of breakdowns in the Network • administration of access control • Performed interviews and on-site inspections

  11. Preliminary findings • NHN executive handling is potentially less efficient due to the lack of adequate routines for handling of derogations and security incidents • The National Heath Network is exposed to external threats: • NHN haven’t provided for sufficient monitoring and security barriers • NHN risk-assessments are not sufficiently adapted to the responsibility of the enterprise, and threats to the Network

  12. Lessons learned • Scope • Investigations concerning information security may also be integrated as part of more comprehensive performance audits • Include ICT-audit experts
