Explanation
Assessed CTEM scenario
Enter the Practitioner CTEM Proving Ground Lab
Free forever, unlimited retakes. You need a LearnCTEM account so your six stage progress and credential can be saved.
The scenario
Acme Logistics runs 42 sites, a hybrid cloud estate, warehouse automation on operational technology networks, thousands of contractor identities, and an acquisition that closed three months ago with no security integration. Leadership has asked for one exposure cycle that reduces real risk to shipping operations within six weeks. You are the practitioner running it.
The six graded stages
- Scoping: decide what this cycle covers and what it deliberately excludes
- Attribution: connect discovered assets to owners, environments, and business services
- Attack path analysis: chain individual weaknesses into paths an attacker can walk
- Prioritization: rank exposures by business impact, reachability, and exploitability
- Validation planning: choose evidence that is safe for production and OT systems
- Mobilization: assign each validated exposure to an owner with a testable action
What you take away
A downloadable CTEM report holding your scope decision, attributed inventory, mapped attack paths, ranked register, validation plan, and named owners, plus a verifiable lab completion certificate.
How to apply this
- Clear the Beginner CTEM Proving Ground Lab first if you are new to exposure management
- Repeat this assessment and defend every decision out loud before your next program review
- Reuse the downloaded report structure for a real cycle at your own organization
- Sit the CTEM Practitioner Certification exam when you are ready
Common mistakes
- Scoping the whole enterprise at once so the cycle never finishes
- Listing findings instead of tracing attack paths
- Running intrusive validation against operational technology
- Mobilizing work without a named owner and a retest
