**5. Forensic tools**

There are many tools to identify, collect, and analyze the forensic data for investigation. Juel et al. developed the PORs tool for the identification of online archives for providing integrity and privacy of files [19]. Dykstra et al. proposed a forensic tool for acquiring the cloud-based data in management plane [6]. It ensures trust in cloud infrastructures. Moreover, Encase and Access data FTK toolkit are used for the identification of trusted data to acquire the evidence. Similarly, tools such as evidence finder and F-response are used to find the evidence related to social networks. Dystra et al. proposed FROST, an open source OpenStack cloud tool for the identification of evidence from virtual disks, API logs, firewall logs, etc. [20].
