How Does Cloud Computing Help in Investigation?

For conventional IT systems, the owner is responsible for all servers beginning from networking equipment to the database as well. Cloud computing offers tools that are very effective for handling and distributing computing resources.

FREMONT, CA: Cloud computing has changed the IT sector, making it possible to deliver the products in a fraction of the time it took earlier. The scalable computing solutions have developed large cloud computing companies such as Amazon Web Services (AWS), Google Cloud and Microsoft Azure. Employees can build or reset an entire computer resource network in three different cloud computing service models, such as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS), by clicking a button.

Cloud Computing and Forensics

Multi-tenancy, jurisdiction, and dependence on CSPs are the unique cloud computing forensic issues. Based on a one-of-a-kind approach to investigating cloud environments, cloud forensics is a sub-topic under digital forensics. CSPs have a lot of servers to host customer data around the world. There are unique challenges in the case of cyber incident laws and legal authority that have controlled the area. In modern CSP settings, the right to choose the location where the information will live is given to the client, and this selection must be made carefully.

The investigator's vital area of interest is to ensure that the third party does not alter the digital evidence so that it can be brought up in a court of law. In the PaaS and SaaS business models, consumers must rely on the cloud service provider to gain access to logs because they lack hardware power.

Compared to the traditional forensics environment, maintaining a custody chain in a cloud environment is a very problematic task. In the traditional forensic world, the internal security team has control over who conducts forensic operations on a machine; on the other hand, in cloud forensics, the security team has no influence over who the CSP wants to gather evidence. This is also necessary to be qualified in accordance with the forensic standards; if this is not done, the custody chain will not be kept in a court of law.
