The cloud computing environment is one of the most promising technologies in the development of computing resources. The cloud service providers provide almost every resource for computing to their users through the internet. With all its advantages, cloud computing has major security issues. Especially in the case of public clouds, anyone can misuse the services for performing unlawful activities. The traditional approaches used for cyber forensics and network forensics are not adequate for the cloud environment because of many technical constraints. There is a need for setting up effective countermeasures that can help an investigator to identify and track unlawful activities happened in a cloud environment. Cloud forensics is an emerging area of research where the researchers aim to provide effective digital forensic techniques that help in the investigation of digital crimes in a cloud environment. The cloud environment helps to extract data even from devices that are not physically accessible. However, cloud forensics is not as easy as it seems; a lot of the success depends on the cloud service model implemented in the context. Getting the support of cloud service providers in accessing the potential sources of evidence necessary for investigation is also a major concern. Another critical aspect of cloud forensics is dealing with legal issues. This chapter discusses the basic concepts of cloud forensics, its challenges, and future directions.

Cloud Computing has emerged as the prime IT computing model for an on-demand access using a pool of shared resources with least IT support. Cloud computing is starting to replace the legacy office IT infrastructure and helpdesk support system. Corporate and home users alike are turning into cloud service consumers in a huge way and moving their data and work to the cloud. Therefore, the CSA between the cloud service consumers and cloud service providers has critical significance that can guarantee the highest-level service quality and delivery. The current CSA fall short on the service delivery commitments with no common terminology or standard followed industry wide by the cloud service providers. Comparing agreements from multiple cloud service providers continues to be an issue. This paper provides a pragmatic approach for Cloud Service Agreements, comparing the current process with the proposed parameters and the new framework for CSA to determine the role of various elements and terms in the decision-making process for cloud service agreements for SaaS, PaaS, IaaS and STaaS.

Disaster recovery is a persistent problem in IT platforms. This problem is more crucial in cloud computing, because Cloud Service Providers (CSPs) have to provide the services to their customers even if the data center is down, due to a disaster. In the past few years, researchers have shown interest to disaster recovery using cloud computing, and a considerable amount of literature has been published in this area. However, to the best of our knowledge, there is a lack of precise survey for detailed analysis of cloud-based disaster recovery. To fill this gap, this paper provides an extensive survey of disaster recovery concepts and research in the cloud environments. We present different taxonomy of disaster recovery mechanisms, main challenges and proposed solutions. We also describe the cloud-based disaster recovery platforms and identify open issues related to disaster recovery.
