As technology advances and cybercrime rates increase, cyberattacks, cyber fraud, and theft of property are becoming serious. Accordingly, digital evidence is inevitable for investigating related crimes. To obtain digital evidence, digital forensics with advanced sensor technology is required following international standards. For digital evidence preservation and processing, the control measures and norms for effective management are critical. Therefore, we analyzed and compared the international standards of digital evidence identification including the International Organization for Standardization/International Organization for Standardization (ISO/IEC 27050) and Digital Evidence Forensics Standard Operating Procedure (DEFSOP). We also studied how to use sensor technology for the standard and operating procedures of digital evidence forensics in real cybercrime. The results provide a basis for constructing effective evidence preservation by identifying principles of digital evidence identification.
