Cloud Computing has challenges to digital forensic evidence in the cloud. Digital forensics is a critical technology for obtaining evidences in crime investigation. Nowadays, the overwhelming magnitude of data and the lack of easy-to-deploy software are among the major obstacles in the field of digital forensics. However, to support forensic examination efficiently using cloud, one has to overcome many challenges such as lack of understanding and experiences on configuring and using digital forensic analytic tools by the investigators, and lack of interoperability among the forensic data processing software. Performing investigation in the cloud environment is practically possible only if support from the Cloud Service Provider (CSP) is made available. Our proposed model-FaaSeC can extend the forensic support from CSP and makes to provide Forensics-as-a-Service (FaaS) to the investigator . The experimental results show that the proposed approaches can significantly reduce forensic data analysis time by parallelizing the workload. The overhead for the investigators to design and configure complex forensic workflows is greatly minimized. The proposed workflow management solution can save up to 87% of analysis time in the tested scenarios.
