What is GSM

A structured investigative approach is essential for an effective production of credible and admissible mobile network evidence. Chapter 2 discussed the ISO/IEC SC27 digital forensic standardization as an effort that helps in developing a robust investigative process, procedures, and methodologies. This chapter applies the ISO/IEC SC27 family of standards for mobile network forensics investigations. Each of the standards is contextualized with the forensic aspects discussed in Chapter 6 together with examples of investigation scenarios, tools, and methods for forensic processing of the mobile network data. These contexts are of practical significance for investigators, elaborating on the approaches for investigative readiness, the techniques and tools for evidence processing from identification to interpretation, and the best practices in handling mobile network evidence data throughout an investigation.
