Sažetak

Information security is related to efforts put in to avoid activities such as unauthorized usage, changing or disseminating of information by having access to these pieces of information. This should not be only thought as capturing of information but also as avoiding the violation of particulars such as integrity, availability, and confidentiality. Vulnerability that occurs in any one of these three basic elements will be evaluated as violation of information security. In this study with the aim to develop a multi-level access control method, Improved Bell-LaPadula security model has been adopted to distributed systems and hence, it was aimed to show how the property of confidentiality, being one of the three basic elements in information security, has been provided. The developed model proposed in the study has been applied on data cluster which has been obtained from real life. Performance of the proposed model has been compared with the performances of Role Based Access Control and Traditional Access Control models. As the obtained results were compared, it was observed that with the proposed model data were provided in a more secure and rapid way to be shared by the users.
