Abstract:This thesis research has been performed at the engineering and consultancy firm Witteveen+Bos. The company is in the process of updating policies on information security and privacy and there is a need to increase awareness and to promote positive information security and privacy behavior. The goal of updating the policies, increasing awareness and promoting positive behavior is to reduce information security and privacy risks and to increase business resilience. Two intervention types to improve information security attitude, subjective norm, perceived behavioral control and laptop locking behavior emerged from an Intervention Mapping process. During the Intervention Mapping it was found that change methods including factors like forms of interaction, cultural similarity and providing cues could be usable in an intervention. The process resulted in an interactive workshop using implementation intentions and signs at the desk to nudge employees to lock their laptops. The workshop was evaluated as a one-group pretest-posttest design and the sign intervention was a field experiment with experimental and control groups. The results showed that the workshop had a statistically significant improvement on the attitude, subjective norm and perceived behavioral control scales regarding information security. After the signs intervention a significant improvement was observed in laptop locking behavior. This means that Witteveen+Bos should consider interactive workshops and sign interventions as two of the tools in the toolbox for improving information security behavior among employees.
