Security Engineering

Official reference

The requirement

Employ architectural designs, software development techniques, and systems engineering principles that promote effective information security within organizational systems.

Assessment objectives

What must be established

Determine if each applicable objective is satisfied. The labels below follow the cited DoD assessment guide.

1. [a]

   architectural designs that promote effective information security are identified;

2. [b]

   software development techniques that promote effective information security are identified;

3. [c]

   systems engineering principles that promote effective information security are identified;

4. [d]

   identified architectural designs that promote effective information security are employed;

5. [e]

   identified software development techniques that promote effective information security are employed; and

6. [f]

   identified systems engineering principles that promote effective information security are employed.

MET requires evidence that all applicable objectives are satisfied. Final, approved evidence is needed. A NOT APPLICABLE determination needs a scope-based basis and is equivalent to MET for scoring. Enduring exceptions and temporary deficiencies have specific conditions under 32 CFR 170.24; they are not a general permission to defer implementation.

GAVII Cybersecurity assessment approach

Connect the objective to the evidence

Identify the architectural principles, development techniques, and engineering practices the organization applies. Purchasing commercial software does not eliminate responsibility for secure system design and integration.

Assessment focus: objectives [a], [b], [c], [d], [e], [f]. Use the methods together; a single example does not establish every objective.

GAVII Cybersecurity’s examples illustrate ways to examine, interview, and test. They are not a mandatory artifact list or a guarantee of an assessment result. Combine methods and address every applicable objective in the actual scope.

Assessment constraints

Scoring and POA&M eligibility

Conditional Level 2 requires a score of at least 88 out of 110 and satisfaction of every eligibility condition. A 1-point requirement is not automatically eligible. The permitted POA&M must be closed through the appropriate closeout assessment within 180 days of the Conditional CMMC Status Date. An operational remediation plan does not confer Conditional Status.

Assessment planning

Location and observation

Not specifically listed in CAP P.11

This requirement is not specifically listed in CAP P.11. That does not establish that remote assessment is sufficient: the Lead CCA and C3PAO determine an adequate approach for the actual scope and evidence.
