Which standard should a security administrator apply for forensics methodologies across a global CSP?

The selection of the International Organization for Standardization (ISO) 27050-1 as the appropriate standard for applying forensic methodologies across a global cloud service provider (CSP) is grounded in its focus on digital evidence and the processes related to it. ISO 27050-1 provides guidelines for the identification, collection, acquisition, and analysis of digital evidence, which are crucial in investigations where security incidents or breaches might occur.

This standard is particularly relevant in a cloud computing context, where data may be stored and processed across various jurisdictions and systems. Adhering to ISO 27050-1 ensures a consistent approach to handling and processing evidence, which is essential for maintaining the integrity of forensics activities and ensuring results are both reliable and admissible in legal proceedings.

In contrast, while the Sarbanes-Oxley Act (SOX) primarily focuses on corporate financial practices and governance for publicly traded companies, it does not specifically address forensic methodologies for digital evidence. The Cloud Controls Matrix (CCM) provides a framework for securing cloud environments but lacks the specificity of forensic practices outlined in ISO 27050-1. The International Electrotechnical Commission (IEC) 27037 focuses on the guidelines for the collection and preservation of digital evidence, but
