Clustering Storage Method for Digital Evidence Storage Using Software Defined Storage

Abstract

The increasing of cybercrime means an increase in the number of digital evidences produced in these criminal activities. Also, to pay attention to the security and integrity of digital data, the construction of digital evidence storage must pay attention to the need for convenience in adding storage and the need for investigators to avoid geographical problems in carrying out their duties. An ideal implementation of the problem is the development of network-based digital evidence storage using the Software-Defined Storage to build a clustered storage system. In this study, we build a clustered storage system using Ceph that will be functioned as digital evidence storage. Ceph is a Software-Defined Storage which is designed to provide excellent performance, reliability and scalability. On the other hand, since digital evidence is fragile, then the security of storage system must also be considered so that the stored digital evidence in the storage system can be accepted in court. The security includes aspects of confidentiality, integrity and availability aspects. We were able to build a storage system using Ceph and as a result, our system storage has met the aforementioned scalability, confidentiality, integrity and availability aspects. The storage system is expected to contribute in terms of digital evidence storage and preservations.
