What you will learn

By the end of the course you will be able to:

  1. 01Tell data, information and evidence apart, and apply the ISO/IEC 27037 principles of relevance, reliability and sufficiency.
  2. 02Work inside your legal authority and written scope, protect privacy and act as an impartial examiner.
  3. 03Recognize where evidence may be and secure a scene without changing it.
  4. 04Choose an acquisition type and prove integrity with hash values and write blocking.
  5. 05Keep chain of custody records and contemporaneous notes that hold up under review.
  6. 06Read file systems, timestamps and common artifacts, and corroborate what they show.
  7. 07Write a report that answers the questions asked, states its limitations and reads clearly to non-specialists.

Before you start

This is a foundation course in forensics, not in IT. It assumes you already know how computers and networks work.

Prerequisites
  • Operating systemsYou use Windows, macOS or Linux beyond the basics: the file system, users and permissions, processes, the command line and system logs.
  • NetworksIP addressing, DNS, DHCP, common protocols (HTTP, HTTPS, SMTP) and what routers and firewalls do.
  • Hardware and storageHard disks, SSDs, memory cards, RAM, and how a device starts up.

Typical background: Two or more years in IT support, systems, networks or security, or a degree in computing.

Not needed
  • Previous forensic experience
  • Forensic software or a lab
  • A legal or law-enforcement background
Coming from law or audit?

You can follow the course, but some lessons will need extra reading on operating systems and networks first.

Are you ready? Take the 2-minute self-check

5 questions on operating systems and networks. Nothing is saved or graded.

Recommended pathDFFCFXorMFXFRETA recommendation, not a rule: every course and exam is open to anyone, in any order.

How to get the most from it

Short, regular sessions work better than one long read.

  1. 1
    Go in order

    Each lesson builds on the one before, and later modules refer back to earlier ones.

  2. 2
    One module per sitting

    A module is about 20 minutes of reading. Add 10 minutes for the checks and your notes.

  3. 3
    Read the Exam focus box first

    It says what the exam expects from that lesson, so you read with a purpose.

  4. 4
    Answer before you look

    Commit to an answer in each knowledge check, then read the explanation, even when you were right.

  5. 5
    Redraw the diagram

    Every lesson has one diagram that sums it up. If you can sketch it from memory, you have the lesson.

  6. 6
    Sign in and come back

    Your place is kept and finished lessons are marked, so short sessions add up.
