Reporting
Summary
PDF p.314Digital forensics reporting summarizes the significant contents of digital data and the investigator's conclusions. It must adhere to strong ethical principles, ensuring unbiased analysis, repeatable methods, and proper handling of evidence.
In plain words
Supplementary — not from your PDFA forensic report sets out the findings and conclusions. It must be unbiased (based only on evidence), use repeatable methods that third parties can reproduce, and justify and document any change to evidence. Otherwise the findings may be thrown out. E-discovery filters the collected data (removing duplicates, searching, tagging), stores it securely, and discloses the same evidence to both sides.
Detailed explanation
PDF p.314Ethical Principles
- Unbiased Analysis: Conclusions should be based solely on direct evidence.
- Repeatable Methods: Analysis methods must be repeatable by third parties.
- Evidence Handling: Ideally, evidence should not be changed. If manipulation is necessary, it must be justified and documented.
- Defense Strategy: Any deviation from ethical behavior can lead to dismissal of findings.
Forensic Examination
- ESI Search: Involves searching the entire drive, including allocated and unallocated sectors.
- E-Discovery: Filters relevant evidence from all data gathered and stores it in a usable format for trials.
E-Discovery Functions
- Identify and De-Duplicate: Filters standard files to reduce data volume.
- Search: Locates files of interest using keyword and semantic search.
- Tags: Applies keywords or labels to organize evidence.
- Security: Ensures evidence is stored, transmitted, and analyzed without tampering.
- Disclosure: Provides the same evidence to both plaintiff and defendant, fulfilling trial requirements.

Examples & real-world scenarios
Supplementary — not from your PDF- Documenting tool versions so another examiner can repeat the analysis.
- De-duplicating standard system files in e-discovery.
- Tagging evidence by relevance.
Scenario
An examiner states a conclusion that goes beyond what the evidence shows. The defence challenges it and the finding is dismissed. Conclusions must rest on direct evidence.
Common mistakes
Supplementary — not from your PDF- Drawing conclusions that aren't directly supported by evidence.
- Using methods others can't repeat.
Practical skills
Supplementary — not from your PDF- List the ethical principles of forensic reporting.
