Understanding Specialized Assets in a CMMC Self-Assessment
DuringCMMC Level 1 Self-Assessments, organizations must classify theirassetsin theSystem Security Plan (SSP).
Specialized Asset Type: Operational Technology (OT)
Operational Technology (OT)includesmachine controllers, industrial control systems (ICS), and assembly machines.
Thesesystems control physical processesin manufacturing, energy, and industrial environments.
OT assets are distinct from traditional IT systemsbecause they haveunique security considerations(e.g., real-time control, legacy system constraints).
Why is the Correct Answer "D. Operational Technology"?
A. IoT (Internet of Things) → Incorrect
IoT devicesinclude smart home systems, connected sensors, and networked appliances, butmachine controllers and assembly machines fall under OT, not IoT.
B. Restricted IS → Incorrect
Restricted Information Systems (IS) refer to classified or highly controlled systems, whichdoes not apply to standard industrial machines.
C. Test Equipment → Incorrect
Test equipment includes diagnostic tools or measurement devicesused forquality assurance, not industrial machine controllers.
D. Operational Technology → Correct
Machine controllers and assembly machinesare part ofindustrial automation and control systems, which are classified asOperational Technology (OT).
CMMC 2.0 References Supporting This Answer:
CMMC Scoping Guidance for Level 1 & Level 2 Assessments
DefinesOperational Technology (OT) as a category of Specialized Assetsthat requirespecific security considerations.
NIST SP 800-82 (Guide to Industrial Control Systems Security)
Identifiesmachine controllers and assembly machinesas part ofOperational Technology (OT).
CMMC 2.0 Asset Classification Guidelines
Specifies thatOT systems should be documented separately in an organization's SSP.
