Understanding SI.L1-3.14.2: Provide Protection from Malicious Code

The CMMC Level 1 practiceSI.L1-3.14.2is based onNIST SP 800-171 Requirement 3.14.2, which requires organizations to:

Implement malicious code protection(e.g., antivirus, endpoint security software).

Ensure coverage across all appropriate locations(e.g., workstations, servers, network entry points).

Keep protection mechanisms updated(e.g., regular signature updates, policy enforcement).

Assessment Criteria for a " MET " Rating:

To determine whether the practice isMET, the Lead Assessor must confirm that:

✔Antivirus or endpoint protection software is installedon all workstations and servers.

✔The solution is centrally managed, ensuring consistent policy enforcement.

✔Signature updates are current, meaning systems are protected against new threats.

✔Logs or reports demonstrate active monitoring and updates.

Why is the Correct Answer " A. It is sufficient, and the audit finding can be rated as MET " ?

The provided evidenceconfirms all necessary requirementsfor SI.L1-3.14.2:

✔All workstations and servers have antivirus installed→Meets installation requirement.

✔A centralized management console is in place→Ensures consistent enforcement.

✔Records show antivirus signatures are up to date→Confirms system protection is current.

Because the evidencemeets the requirement, the practice should berated as MET.

Why Are the Other Answers Incorrect?

B. It is insufficient, and the audit finding can be rated NOT MET → Incorrect

The evidence providedmeets all necessary requirements, so the practiceshould not be rated as NOT MET.

C. It is sufficient, and the Lead Assessor should seek more evidence → Incorrect

Ifadequate evidence already exists,additional evidence is unnecessary.

D. It is insufficient, and the Lead Assessor should seek more evidence → Incorrect

The evidence providedmeets the control requirements, making itsufficient.

CMMC 2.0 References Supporting This Answer:

CMMC Assessment Process (CAP) Document

Specifies that a practice can be marked asMET if sufficient evidence is provided.

NIST SP 800-171 (Requirement 3.14.2)

Defines the standard formalicious code protection, which ismet by antivirus with active updates.

CMMC 2.0 Level 1 (Foundational) Requirements

Clarifies that basic cybersecurity measures likeantivirus installation and updatesmeet compliance forSI.L1-3.14.2.

Final Answer:

✔A. It is sufficient, and the audit finding can be rated as MET.

Understanding the Assessment Environment Requirement

During aCMMC Level 2 assessment, assessors requireobjective evidencethat security controls are implementedin the actual operating environmentwhereControlled Unclassified Information (CUI)is handled.

This means thattests or demonstrations must be conducted in the production environment, where the organization’s real systems and security controls are in use.

Why Option B (Production) is Correct

Assessment teams need to validate security controls in the actual environment where they are applied, ensuring that security measures are in effect in thereal-world operating conditions.

Option A (Client)is incorrect because " Client " is not a defined assessment environment.

Option C (Development)is incorrect because testing in a development environmentdoes not accurately represent the production security posture.

Option D (Demonstration)is incorrect becausedemonstrations in a separate test environment do not provide valid evidence for CMMC assessments—actual security implementations must be verified in production.

NIST SP 800-171 Assessment Procedures(Verification must occur in the actual system where CUI resides.)

Final Verification

SinceCMMC assessments require security controls to be validated in the actual production environment, the correct answer isOption B: Production.

Per the CMMC Assessment Process (CAP), when planning an assessment, the Lead Assessor must coordinate with the Organization Seeking Certification (OSC) to select interview participants who can provide clarity and understanding of their practice activities. The intent is to interview individuals directly involved with and knowledgeable about the processes and practices under review, rather than selecting personnel based solely on rank, clearance, or formal expertise in CMMC.

This ensures the assessment is evidence-based and grounded in how practices are actually performed within the OSC.
