High School IntermediateModule I12Defensive and Fictional

I12 Digital Forensics Basics

Learn how authorized defenders preserve, organize, analyze, correlate, explain, and report fictional digital evidence. This module focuses on evidence integrity, chain of custody, source lineage, file and metadata artifacts, volatile-evidence concepts, timeline reasoning, professional reporting, privacy, and portfolio-safe communication.

Module Snapshot

Build Trustworthy Findings without Changing or Overstating the Evidence

Digital forensics is not about searching everything or proving a dramatic story. It is a disciplined, authorized process for answering defined questions with preserved evidence, documented methods, reproducible analysis, visible limitations, and professional reporting.

8 lessons

Concepts, guided analysis, and one integrated lab

1 module test

Twenty-five questions with hidden answers

1 portfolio package

A fictional forensic case file and report

Main Question

How Can a Defender Turn Digital Records into Trustworthy, Reproducible Findings?

A professional fictional case connects authorization, collection, preservation, integrity, source health, artifact interpretation, timeline reasoning, competing explanations, confidence, reporting, privacy, review, and decision support.

Six-Step Workflow

The Intermediate Digital Forensics Workflow

Define the authorized question

Set the fictional case objective, approved scope, privacy boundary, responsible owner, evidence need, decision requirement, and stop conditions.

Identify and preserve evidence

Locate supplied fictional file, disk, identity, process, memory, network, cloud, application, support, and business records without changing their meaning.

Verify integrity and lineage

Record fictional identifiers, source, collection time, owner, handling history, integrity checks, derived copies, limitations, and chain-of-custody transitions.

Analyze artifacts

Examine fictional metadata, file activity, process relationships, sessions, connections, cloud events, and alternate explanations.

Correlate and test

Compare independent fictional sources, normalize timestamps, document source delay and conflicts, challenge assumptions, and assign confidence.

Report and preserve

Create fictional findings, exhibits, limitations, actions, owner decisions, reviewer notes, and a portfolio-safe final case record.

Learning Objectives

What You Will Be Able to Do

Objective 1

Explain the purpose, limits, ethics, authorization, privacy, and defensive role of digital forensics.

Objective 2

Plan fictional evidence collection using case questions, volatility, relevance, accessibility, ownership, and preservation needs.

Objective 3

Maintain fictional evidence integrity, chain of custody, source lineage, working copies, handling history, and documented limitations.

Objective 4

Analyze fictional files, metadata, processes, volatile-evidence concepts, network records, cloud activity, and timelines without overstating conclusions.

Objective 5

Correlate fictional evidence across independent sources while accounting for source health, delay, clock differences, duplication, conflicts, and gaps.

Objective 6

Create a professional fictional forensic report with facts, supported findings, alternatives, confidence, limitations, exhibits, actions, and portfolio-safe communication.

Module Lessons

Eight Lessons from Authorization to Final Reporting

I12.1Lesson 1 of 8

Digital Forensics Purpose, Ethics, and Authorization

Focus

Understand what digital forensics can and cannot prove, why authorization and privacy limits matter, and how case questions guide every collection and analysis decision.

Defensive Lab

Build a fictional authorization brief with objective, scope, owner, privacy limits, excluded actions, decision needs, and stop conditions.

Open I12.1

I12.2Lesson 2 of 8

Evidence Sources and Collection Planning

Focus

Identify fictional disk, file, account, application, endpoint, memory, process, network, cloud, backup, support, and business evidence and prioritize collection safely.

Defensive Lab

Create a fictional collection plan covering source, reason, owner, order, preservation, dependency, limitation, alternate source, and completion evidence.

Open I12.2

I12.3Lesson 3 of 8

Evidence Integrity, Hashes, and Chain of Custody

Focus

Use fictional integrity checks, evidence identifiers, originals, working copies, source lineage, handling history, transfer records, and chain-of-custody documentation.

Defensive Lab

Complete a fictional evidence register and handling trail for originals, preserved images, exports, timelines, screenshots, notes, and reviewed copies.

Open I12.3

I12.4Lesson 4 of 8

File, Metadata, and Artifact Analysis

Focus

Interpret fictional filenames, paths, extensions, timestamps, ownership, metadata, document properties, shortcuts, caches, recent-item records, and deletion indicators.

Defensive Lab

Analyze a fictional artifact set and separate observations, supported findings, alternatives, confidence, gaps, and follow-up evidence needs.

Open I12.4

I12.5Lesson 5 of 8

Memory, Process, and Volatile Evidence Concepts

Focus

Study defensive concepts for fictional running processes, parent-child relationships, sessions, connections, loaded modules, temporary data, volatility, and collection order.

Defensive Lab

Review a fictional volatile-evidence snapshot and build a process-and-session map without executing commands or inspecting a real device.

Open I12.5

I12.6Lesson 6 of 8

Network, Cloud, and Timeline Correlation

Focus

Correlate fictional authentication, network, DNS, proxy, storage, cloud, deployment, support, and business events while preserving source health and uncertainty.

Defensive Lab

Build a fictional normalized timeline, identify conflicts and gaps, assign confidence, and explain which conclusions remain supported.

Open I12.6

I12.7Lesson 7 of 8

Reporting, Findings, and Case Communication

Focus

Write fictional forensic findings that separate evidence, observation, interpretation, alternatives, confidence, limitation, impact boundary, owner action, and reviewer needs.

Defensive Lab

Create a fictional technical report, leadership summary, exhibit list, limitation statement, correction record, and portfolio-safe case summary.

Open I12.7

I12.8Lesson 8 of 8

Digital Forensics Basics Lab

Focus

Integrate authorization, collection, preservation, integrity, chain of custody, artifact analysis, volatile evidence, correlation, timeline building, reporting, and review.

Defensive Lab

Complete the fictional Northbridge Research Archive case with an evidence register, collection plan, artifact analysis, process map, timeline, findings matrix, and final report.

Open I12.8

Fictional Evidence Preview

Northbridge Research Archive Case

The integrated lab uses a fictional archive-export case with conflicting timestamps, duplicate content, an approved service workflow, an outdated configuration reference, delayed application records, and no supported external sharing.

E-01

Support report

A fictional researcher reports that an approved archive export created an unexpected duplicate folder.

Provides the original observation but does not prove how the duplicate was created.

E-02

File metadata

Five duplicate files have matching content hashes but different path and creation metadata.

Supports duplication of known content while preserving uncertainty about the process.

E-03

Identity record

An approved service identity accessed the archive during the documented export window.

Connects an authorized workflow to the time window without proving every file operation.

E-04

Process snapshot

A scheduled export worker launched a child copy process using an outdated configuration reference.

Supports a technical explanation that must be correlated with other records.

E-05

Cloud audit

No external sharing, public-link creation, or unrelated-account download appears in the supplied window.

Narrows supported impact within source-health and retention boundaries.

E-06

Source health

Application audit delivery was delayed by twelve minutes while identity, storage, cloud, and support records remained current.

Requires a visible limitation and later timeline revision.

Portfolio Outcome

Fictional Digital Forensics Case Package

Build a portfolio-safe authorization brief, collection plan, evidence register, chain-of-custody record, artifact analysis, volatile-evidence map, normalized timeline, findings matrix, technical report, leadership summary, limitation statement, evidence exhibit list, and reviewer checklist.
