Abstract There are two elements of security policy that can have a bearing on its effectiveness: content and form. While the content of the security policy has been investigated extensively in the most of the previous studies, there is very little literature on the form of the security policy. Since the form of the policy influences its success, it is important to understand how to articulate the form of a security policy. Thus, the aim of this study is to investigate the relationship between security form and policy compliance of employees. Research results find that dimensions of security form have effect on attitude towards security compliance, subjective norm, perceived behavioral control, and perceived response costs, and besides attitude towards security compliance and subjective norm have an effect on persistent security compliance intention. The conclusions and implications are discussed. Key Words : Security Policy, Policy Compliance, Policy Content, Policy Form, Theory of Planned Behavior
