It is widely acknowledged that norms and culture influence decisions related to information security. The purpose of this paper is to investigate how work-related groups influence information security policy compliance intentions and to what extent this influence is captured by the Theory of Planned Behavior, an established model over individual decision-making.
A multilevel model is used to test the influence of work-related groups using a cluster sample of responses from 2,291 employees from 203 worksites, 119 organizations, 6 industries and 38 professions.
The results suggest that work-related groups influence individuals’ decision-making in the manner in which contemporary theories of information security culture posit. However, the influence is weak to modest and overshadowed by individual perceptions that are straightforward to measure.
This paper is limited to one national culture and four types of work-related groups. However, the results suggest that the Theory of Planned Behavior captures most of the influence that work-related groups have on decision-making. Future research on security culture and similar phenomena should take this into account.
Information security perceptions in work-related groups are diverse and information security decisions appear to be based on individual perceptions and priorities rather than groupthink or peer-pressure. Security management interventions may be more effective if they target individuals rather than groups.
This paper tests some of the basic ideas related to information security culture and its influence on individuals’ decision-making.
