"Check, Check, Check, We Got Those" - Catalogue Use in Information Security Risk Management.

Information Security Risk Management (ISRM) is fundamental in most organisations today. The literature describes ISRM as a complex activity, and one way of addressing this is to enable knowledge reuse in the shape of catalogues. Catalogues in the ISRM domain can contain lists of, e.g. assets, threats and security controls. In this paper, we focus on three aspects of catalogue use. Why we need catalogues, how catalogue granularity is perceived, and how catalogues help novices in practice. As catalogue use is not yet a widespread practice in the ISRM, we have selected a domain where catalogues are a part of the ISRM work. In this case, the Air Traffic Management (ATM) domain uses a methodology that includes catalogues and is built on ISO/IEC 27005. The results are based on data collected from 19 interviews with ATM professionals that are either experts or novices in ISRM. With this paper, we nuance the view on what catalogues can contribute with. For example, consistency, coherency, a starting point and new viewpoints. At the same time, we identify the need to inform about the aim of the catalogues and the limitations that come with catalogue use in order to leverage the use – especially from a novice perspective.
