Abstract [en]

Content validity, the extent to which a measurement reflects the specific intended domain of content, is a basic type of validity for a valid measurement. It has usually been examined using qualitative methods and has not been given as much attention as the other psychometric properties such as internal consistency reliability, indicator reliability and construct validity in the IS field. In this paper, a quantitative approach including the proportion of substantive agreement (PSA), and substantive validity (CSV) was used to examine content validity for 80 items covering eighth domains related to organizational and individual perspectives of information security. The content validity for the organizational perspective was examined using data from a total of 56 content domain experts. Data from 51 experts were further used to examine content validity for the individual perspective of information security. 31 items did not have an adequate content validity, leaving the instrument with 49 items that have been evaluated for their content validity and can be used in future empirically tests of hypotheses in the information security field. To the knowledge of the authors this quantitative method to assess content validity of items in the process of developing instruments hasn’t yet been applied in the field information security.

Abstract [en]

Today, few companies would manage to continuously stay competitive without the proper utilization of information technology (IT). This has increased companies’ dependency of IT and created new threats that need to be addressed to mitigate risks to daily business operations. A large extent of these IT-related threats includes hackers attempting to gain unauthorized access to internal computer networks by exploiting vulnerabilities in the behaviors of employees. A common way to exploit human vulnerabilities is to deceive and manipulate employees through the use of social engineering. Although researchers have attempted to understand social engineering, there is a lack of empirical research capturing multilevel factors explaining what drives employees’ existing behaviors and how these behaviors can be improved. This is addressed in this thesis.

The contribution of this thesis includes (i) an instrument to measure security behaviors and its multilevel determinants, (ii) identification of multilevel variables that significantly influence employees’ intent for behavior change, (iii) identification of what behavioral governance factors that lay the foundation for behavior change, (iv) identification that national culture has a significant effect on how organizations cope with behavioral information security threats, and (v) a strategy to ensure adequate information security behaviors throughout an organization.

This thesis is a composite thesis of eight papers. Paper 1 describes the instrument measuring multilevel determinants. Paper 2 and 3 describes how security knowledge is established in organizations, and the effect on employee information security awareness. In Paper 4 the root cause of employees’ intention to change their behaviors and resist social engineering is described. Paper 5 and 8 describes how the instrument to measure social engineering security behaviors was developed and validated through scenario-based surveys and phishing experiments. Paper 6 and 7 describes experiments performed to understand reason to why employees fall for social engineering. Finally, paper 2, 5 and 6 examines the moderating effect of national culture.
