This chapter surveys the systematic analysis of the forensic process, challenges in cloud forensics, and in particular the data collection techniques in the cloud environment. This causes high resource consumption and also results in prolonged unavailability of cloud services. The availability of massive computation power and storage facilities at very low cost motivates a malicious individual or an attacker to launch attacks from machines either from inside or outside the cloud. It provides on-demand services to the users by allocating virtual instances and software services, thereby reducing customer’s operating cost. In order to provide services efficiently at a low cost, cloud computing has emerged as one of the prominent technologies. Its usage has been increasing tremendously over the years. Internet plays a vital role in providing various services to people all over the world.
