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 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
- Run the Beginner CTEM Practice Lab first if you are new to exposure management
- Repeat this lab 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
