Enterprise Cloud Forensics and Incident Response, Re: SANS FOR509 OnDemand Experience

I am fortunate to be employed at an organization that considers a training budget beyond the allotted tuition reimbursement. I don’t ever expect or take the opportunity for granted, so it’s great news when an opportunity to take a course is offered and approved.

I considered a handful of courses. Among them was FOR509, Enterprise Cloud Forensics and Incident Response, in part due to a tweet by David Cowen.

Several surveys and reports suggest more organizations are migrating from on-premise to cloud environments. The DFIR opportunity is certainly there. Aside some knowledge and interaction with one of the cloud platforms, I don’t have any other experience. Further, there doesn’t appear to be another class like it. This direction (FOR509), for me, made sense.

Cowen reinforced my reasoning in the recorded introduction of the course: “If you’re saying to yourself, ‘Dave, I’m never going to use one of those clouds. My work and projects simply don’t take me there.’ I think you’ll find in the future you might end up there anyway […]. So you need to be prepared.” I like to be prepared.

Based on the 4-day syllabus, I expected the following:

  1. Sufficient coverage of cloud fundamentals so I may comprehend the related material.
  2. Sufficient description of each cloud platform’s features and platform specific terminology to be able to understand and communicate with the people who maintain it.
  3. Concise descriptions of what logs are available and how to analyze them for an incident.

FOR509 (OnDemand) absolutely fulfilled my expectations. In addition to a satisfactory understanding of the relevant logs covered, I perceive that I am better able to analyze new logs as I encounter them. I’m already cleaned up a SIEM dashboard based on what I learned.

Can you figure it out on your own? Absolutely. A SANS course with configured labs just makes learning efficient. The FOR509 labs will continue to be useful from time to time, as I do the labs from FOR500 and FOR508.

I would recommend this course if you:

  1. have a strong desire or interest to learn about incident response involving enterprise cloud environments, or
  2. are an individual with exposure to at least one of the covered cloud providers in an organization with incident response or internal investigation related responsibilities.

I suspect this applies to most SANS courses – I wouldn’t recommend FOR509 if you have no intention of completing the labs and expect to retain any information. I perceive that there is significant value in the lab exercises. This is especially true if exposure to any of the covered cloud providers is limited.

Colorfully tabbed SANS books.

While FOR509 advertises that previous cloud knowledge is not necessary (it’s true), below are some resources that may be helpful to prime you for the course. Previous experience working with a SIEM (also not necessary) is helpful, too.

In the updated course, FOR509 includes Google Workspace, Kubernetes forensics and IR, and a capstone challenge. With the rapid changes and updates to the course already baked in, I look forward to taking this course again at a discounted rate. If you took the 4-day course, as I did, SANS has a special offer for alumni to take the entire 6-day course for the price of the last two days. Bonus: The GIAC Cloud Forensics Responder (GCFR) certification is now available.

Megan Roddie will introduce the cloud forensics and IR poster on 08/02/2022, which will undoubtedly help as a reliable and accessible reference.

Having completed the 4-day OnDemand course, Cowen’s preview of the FOR509 6-day course on the SANS Digital Forensics and Incident Response YouTube channel is an accurate representation of what you will learn. I really enjoyed my learning experience with FOR509. I imagine that if you’re reading this blog for information about FOR509, you will enjoy it too.
