This paper addresses the management of non-custodian data sources external to the organization within the framework of ISO/IEC 27050 standards, which provide a structured approach for their identification, preservation, and analysis. As new technologies continue to proliferate, the rigorous handling of this type of evidence becomes critical in legal and forensic contexts. The challenges and opportunities associated with the application of these standards are examined, highlighting the importance of personnel training and interdisciplinary collaboration to ensure the integrity and legality of data collection. The study emphasizes that the effective implementation of ISO/IEC 27050 standards is essential for mitigating risks related to evidence tampering, thereby promoting transparency and trust in judicial processes.
