Abstract

Malacious Insiders are a serious security challenge to every organization due to their intimate knowledge of organization's valuable informationa assets, resources and priviliged access to those resources. Every organization needs to implement a defensive security policy to safeguard themselves from the security risks. To address insider threat problems, we implemented a framework which establishes trustworthiness among the employees based on Multi-User approval strategy. The framework uses a hierarchial structure of the employees in the organization such that if any user requires access to certain classified information, the framework selects a set of approvers randomly and sends the request to thoseapprovers who are authorized to grant permissions. We implemented an application based on this framework to accomplish the goal and a thorough performance analysis is conducted to arrive at the result.
