CTCH 665 at the University of Maryland Global Campus is a graduate course on the tools, procedures and best practices of digital forensic examinations.
UMGC lists procedures for securing and validating evidence (including digital media and physical memory), recovering artifacts, and analyzing, reporting and presenting results in criminal and civil situations. Experience with mobile forensic analysis is also provided.
Students find the course exacting because forensic work must hold up to scrutiny. A finding is only as strong as the documentation showing how the evidence was handled.

Key Concepts Explained
Chain of Custody
The chain of custody records who handled evidence, when and why, from seizure to court. A gap in the chain can make good evidence unusable.
Hashing to Validate Evidence
Examiners work on a forensic copy (image), not the original. A cryptographic hash of the original and the image, such as SHA-256, proves they are identical.
Example: An examiner images a USB drive through a write blocker and records the SHA-256 hash of the drive and of the image. They match. Weeks later, before writing the report, the examiner re-hashes the image and gets the same value, showing the evidence has not changed since acquisition. Both hash values, dates and tools go into the report.
Order of Volatility
Some evidence disappears faster than other evidence. Guidance such as RFC 3227 recommends collecting the most volatile first: memory and network state before disk contents, and disk before archived backups.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Acquisition lab | Sound evidence handling | Record tools, hashes and every step taken |
| Artifact analysis | Finding relevant evidence | Link each artifact to a case question |
| Mobile forensics exercise | Phone data extraction and review | Note extraction method and its limits |
| Forensic report | Clear, neutral presentation | State facts, method and findings without speculation |
Mobile Forensics Basics
Phones hold messages, locations, app data and photos, which makes them central to many cases. They are also harder to examine than computers because of encryption, locked bootloaders and frequent operating system updates.
Extraction methods are often described in levels:
| Method | What it captures |
|---|---|
| Manual | What an examiner can see on screen, photographed |
| Logical | Files and data the device's operating system exposes |
| File system | A fuller set of files, including some app databases |
| Physical | A bit-for-bit copy, where the device allows it |
Your report should state which method was used and what it could not capture. Also note steps taken to isolate the device from networks, since a remote wipe or new incoming data could alter evidence.
Where Students Get Stuck
- Opinion in place of findings. Forensic reports state what the evidence shows; leave guilt to the court.
- Missing method detail. Another examiner should be able to repeat your work from the report.
- Ignoring legal context. Criminal and civil cases have different expectations; follow the scenario.
- Jargon overload. Explain technical terms for a non-technical reader such as a judge.
Study Tips for CTCH 665
- Make chain of custody and hash records a habit in every lab.
- Learn where common artifacts live, such as browser history, recent files and system logs.
- Write findings as numbered, factual statements with evidence references.
- Practice summarizing a technical finding in two plain sentences.
