This lesson develops practical capability in Forensic Principles, Legal Authority, Ethics, and Chain of Custody within Certified Digital Forensics Examiner (CDFE) Training. Activities reflect an investigation team handling cybercrime, misconduct, fraud, insider-risk, and incident-response evidence, so requirements, decisions, evidence, findings, and improvement actions remain connected.
The lesson supports the wider objective to conduct defensible digital investigations by preserving evidence, acquiring data, analysing technologies, and communicating supported conclusions.
The instructor demonstrates the forensic principles, legal authority, ethics, and chain of custody workflow, identifies the applicable inputs and responsibilities, records checkpoints in forensic case plan and custody record, and contrasts the accepted state with a condition where evidence is collected without documenting who controlled it.
Complete a controlled implementation, audit, assessment, or foundation exercise for Forensic Principles, Legal Authority, Ethics, and Chain of Custody. Establish scope and criteria, collect or create evidence, examine “evidence is collected without documenting who controlled it,” reach a supported conclusion, and preserve the result in forensic case plan and custody record.
Separate missing evidence from ineffective practice, and distinguish a documentation issue from a control, process, governance, or competence failure. Use forensic case plan and custody record to trace the earliest divergence. Treat “evidence is collected without documenting who controlled it” as a hypothesis until the response is validated against the applicable requirement and intended outcome.
Learners can apply Forensic Principles, Legal Authority, Ethics, and Chain of Custody, explain the reasoning used, and defend the result through forensic case plan and custody record.
