The emergence of cloud services offered many benefits for less tech savvy individuals, because it offers easy accessible computing or storage solutions for every customer. The adoption among individuals surpassed the adoption by organizations like businesses or public institutions due the tremendous benefits of cloud services for customers. Due the lacking adoption by public institutions, we see an increasing deviant use of such services in environments, where the IS policy actually prohibits a use of not approved third-party service. Current research has only a basic understanding on what drives the deviant cloud usage within organizations and the apparent influence of personality traits on the usage of Shadow IT has not been evaluated, yet. It is expectable that individuals with an affinity towards IT innovations use information systems before they are approved by organizational IS security policies and not users reluctant towards technology. A granular knowledge of different types of deviant users is helpful in order to develop strategies to address specific mechanisms of justifying violations of IS policies by using not approved cloud services. Our preliminary findings among public officials show that users with a high personal innovativeness are less likely to behave in compliance to the IS security policy.
