Bakgrunnsstudie til metode for identifisering ig rangering av kritiske samfunnsfunksjoner

The report documents supplementary work done in BAS5 in developing a methodology to identify and rank critical societal sectors and ICT systems. It provides necessary documentation for the work with the methodology, and it has also had the role of an ideas bank as the methodology has been developed. The report raises and discusses questions, for instance: Which questions should a Norwegian methodology address? Should it aim to provide an answer as to what is most critical within a single sector or an infrastructure? Should it address large systems, or even include singular objects within infrastructures? In what kind of situations should it be used; before, during or after a crisis? Can it be used to direct national emergency preparedness resources? Should it help in identifying areas for further analysis (including risk analysis)? Is it to be a tool for the government, or should it also be a methodology usable for private and public enterprises? Furthermore, how detailed and extensive can the methodology possibly be, what qualifications are needed by its users, and how should the methodology be developed and maintained? The target group for this report is narrower than the report on the methodology. Primarily, this report is written for the BAS5 project group and others with need for supplementary information on the methodology.
