Forget the Fluff: Examining How Media Richness Influences the Impact of Information Security Training on Secure Behavior

User-initiated security breaches are common and can be very costly to organizations. Information security training can be used as an effective tool to improve users´ secure behavior and thus alleviate security breaches. Via the lens of learning, media richness, and cognitive load theories, this research examines how to improve the effectiveness of security training. We conduct a realistic laboratory experiment to examine the influence of training with different degrees of media richness on secure behavior. We found that training with lean media richness improved secure behavior more than training with highly-rich media. Suggestions for researchers and practitioners are provided.
