01 Digital Forensics Labs

For the EC-Council → Labs → Digital Forensics Labs section, I recommend keeping this focused to 10 high-value labs that align strongly with CHFI skills, SOC/incident response work, and real-world forensic investigations.

The sequence should take the learner through the complete forensic lifecycle:

Identify → Preserve → Collect → Examine → Analyze → Correlate → Reconstruct → Document → Report

The lab should focus on analysis of provided memory evidence, not acquiring sensitive memory from unrelated systems.

Primary Deliverable

Memory Forensics Findings Register

Lab 07 — Browser, Email & Phishing Forensics

This combines several closely related user-activity evidence sources rather than creating too many small labs.

Mission

Investigate a simulated phishing incident by correlating email, browser, download, and endpoint artifacts.

Email Evidence

Learners review:

sender
recipient
subject
timestamps
message headers
routing information
reply-to
URLs
attachments
authentication results where available

Browser Evidence

Investigate:

browsing history
downloads
timestamps
visited domains
cached information
cookies where appropriate
downloaded filenames

Investigation Story

Email Received
      ↓
Link Opened
      ↓
Website Visited
      ↓
File Downloaded
      ↓
File Accessed
      ↓
Endpoint Activity

The learner must determine whether the evidence supports this sequence.

Important Principle

Correlation is stronger than relying on one artifact.

Primary Deliverable

which protocols were involved
whether communication matches expected system behavior

Primary Deliverable

Lab 09 — Incident Timeline Reconstruction & Evidence Correlation

This should be the major analytical lab before the capstone.

Mission

Combine evidence from multiple sources and reconstruct a defensible incident timeline.

Evidence Sources

Provide learners with:

Windows Logs

Linux Logs

Authentication Logs

Web Logs

DNS Logs

Firewall Logs

Browser History

Email Evidence

Filesystem Metadata

Network PCAP

Core Methodology

Timestamp → Event → Source → Actor → Asset → Action → Evidence → Confidence

Timeline Example

Time	Asset	Evidence Source	Event	Confidence
09:14	User01	Email	Message received	Confirmed
09:18	User01	Browser	URL visited	Confirmed
09:19	User01	Browser	File downloaded	Confirmed
09:22	User01	Endpoint	Program activity	Supported
09:25	User01	DNS	Domain resolved	Confirmed
09:26	User01	Network	Connection observed	Confirmed

Critical Skill

Learners must distinguish:

Observed Fact

from:

Interpretation

from:

Hypothesis

For example:

Fact: A connection occurred at 09:26.

Interpretation: The connection followed execution of the downloaded file.

Hypothesis: The downloaded file initiated the connection.

The third statement requires sufficient evidence before being presented as confirmed.

Primary Deliverable

Incident Timeline + Evidence Correlation Report

Lab 10 — Enterprise Digital Forensics Capstone

Final Digital Forensics Investigation

This should combine everything from Labs 01–09.

Mission

Learners receive a fictional enterprise incident and act as the assigned Digital Forensics Investigator.

The investigation begins with an incident notification:

A user reported unusual workstation activity after interacting with a suspicious email. Security monitoring subsequently identified unusual authentication and network activity. The investigation team has preserved several evidence sources for forensic examination.

The learner receives:

Disk Evidence

Memory Evidence

Windows Logs

Linux / Server Logs

Email Evidence

Browser Artifacts

DNS Logs

Firewall Logs

Network PCAP

Why these 10 are enough

This gives us a much tighter progression than creating 15–20 overlapping forensic labs:

Evidence → Disk → Files → Windows → Linux → Memory → User Activity → Network → Timeline → Enterprise Investigation

It covers the core practical skills around CHFI, while also supporting the CSA and ECIH paths without duplicating entire SOC and incident-response lab tracks.

The next step should be Lab 01 — Digital Evidence Handling & Chain of Custody, built in the same detailed GoHackersCloud mission format as the Ethical Hacking labs.
