Abstract:

Cloud computing is a new type of computing concept. It is based on open standards and services, and it is centered on the Internet. It makes all kinds of resources on the Internet to work together, which constitutes some huge data centers and computing centers, offering the safe, fast and convenient data storage and network computing services for all kinds of users. Under the cloud computing environment, the Internet is facing more and more computer crimes, bringing great challenges to forensic work. On the one hand, the evidences of the attacks that have taken place should be collected and analyzed. On the other hand, experimental data should be collected for the technical means of preventing attacks. Cloud computing environment is the attacker's new target, and once the attack is successful, the losses will directly affect the users' data security and data integrity. Among the attacks, DDoS attack is still one of the attacks that occur most easily and most difficult to prevent on the cloud computing platform. This paper discusses the DDoS attack problems in the cloud computing environment, proposes a model of cloud forensics framework under the simulation DDoS attack scenarios on the basis of related work.
