Which standard addresses practices related to acquisition of forensic artifacts and can be directly applied to a cloud environment?

The standard that addresses practices related to the acquisition of forensic artifacts and can be directly applied to a cloud environment is ISO/IEC 27050-1. This standard specifically provides guidelines for electronic evidence and its management, including aspects essential for conducting digital forensics. In the cloud context, it emphasizes the importance of preserving the integrity and authenticity of digital evidence, which is critical when cloud services are involved.

ISO/IEC 27050-1 outlines processes for identifying, collecting, analyzing, and storing electronic evidence, helping organizations ensure that they follow legal and regulatory requirements during incidents that might involve cloud resources. As cloud environments can present unique challenges related to data ownership, location, and access, having a standard specifically tailored to managing forensic artifacts within such environments is essential for effective security management and compliance.

The other options relate to different aspects of security and management but do not focus specifically on forensic artifact acquisition in a cloud context. For instance, NIST SP 500-291 addresses cloud computing standards broadly, while NIST SP 800-145 describes cloud computing definitions, and ISO/IEC 27001 is concerned with information security management systems and does not delve into the specifics of forensic artifacts.
