Domains

High-level security areas used to organize requirements.

Level 1 assesses practices across 6 of the 14 domains.

Controls

Basic security practices required to protect Federal Contract Information (FCI).
FAR 52.204-21 defines 17 safeguarding requirements.

15 are assessed under CMMC Level 1, while the remaining 2 requirements are enforced through DFARS contract obligations and are not directly assessed as CMMC practices.

Objectives

Across the 15 controls, Level 1 includes 30 assessment objectives. Each control is unpacked into one or more objective-level actions that you must demonstrate during a self-assessment.

CMMC Level 1 Requires 17 Safeguards 15 Controls

The official FAR clause lists 15 safeguards, but CMMC documentation often references 17 practices. Here is why: 

CMMC inherited the DoD’s earlier mapping from the DFARS 252.204-21 “Basic Safeguarding” table, where two of the FAR requirements were split into multiple CMMC practice IDs during modeling. They are not additional requirements—just a structural carryover from the original DoD-to-NIST mapping exercise.
