Computer Forensics Foundation — Lesson 3: File Systems, Deleted Data, Logs, Timelines, User Artifacts, and Analysis

Learning Objectives

• Interpret the principles, requirements, roles, and dependencies shaping file systems, deleted data, logs, timelines, user artifacts, and analysis.
• Apply a repeatable workflow and produce a reviewable artifact analysis and timeline workbook.
• Evaluate normal operations, the exception where file systems is undocumented or assigned to conflicting owners, and appropriate follow-up actions.

Detailed Topics

• File Systems within the context of Computer Forensics Foundation.
• Deleted Data within the context of Computer Forensics Foundation.
• Logs within the context of Computer Forensics Foundation.
• Timelines within the context of Computer Forensics Foundation.
• User Artifacts within the context of Computer Forensics Foundation.
• Analysis within the context of Computer Forensics Foundation.

Instructor Demonstration

The instructor traces a realistic case involving an investigation team examining endpoints, removable media, user activity, and system artifacts after a suspected security incident. The demonstration shows how to define scope and criteria, collect evidence, record decisions in artifact analysis and timeline workbook, and challenge the condition where file systems is undocumented or assigned to conflicting owners.

Hands-On Exercise

Complete a controlled exercise for File Systems, Deleted Data, Logs, Timelines, User Artifacts, and Analysis. Establish responsibilities and acceptance criteria, examine the case where file systems is undocumented or assigned to conflicting owners, reach a supported conclusion, and preserve the result in artifact analysis and timeline workbook.

1. Confirm the objective, scope, roles, criteria, and expected work product.
2. Perform the activity while recording assumptions, evidence, and decisions.
3. Test a normal case, the stated exception, and a follow-up condition.
4. Document conclusions, ownership, deadlines, escalation, and verification requirements.

Scenario Analysis

• Identify the requirement, principle, or control with the strongest influence on file systems, deleted data, logs, timelines, user artifacts, and analysis.
• Compare two defensible responses and explain their operational, risk, and evidence trade-offs.
• Determine how artifact analysis and timeline workbook should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Begin with the earliest point where expected practice and observed evidence diverge. Separate a missing record from an ineffective process, and distinguish role ambiguity from a control or competence failure. Treat “file systems is undocumented or assigned to conflicting owners” as a hypothesis until the response is tested against the applicable criteria and intended outcome.

Validation Checklist

• The scope, roles, criteria, stakeholders, and intended outcome for file systems, deleted data, logs, timelines, user artifacts, and analysis are explicit.
• The artifact analysis and timeline workbook connects conclusions to objective, reviewable support.
• Normal operation, the stated exception, escalation, and follow-up were evaluated.
• Owners, due dates, verification methods, review triggers, and improvement actions are clear.

Lesson Outcome

Learners can apply File Systems, Deleted Data, Logs, Timelines, User Artifacts, and Analysis, explain the reasoning used, and defend the result through artifact analysis and timeline workbook.
