While assessing a company, the CCA is determining whether the company controls and manages connections between its corporate network and all external networks. The company has: (1) a strict employee policy prohibiting personal Internet use and personal email on company computers, and (2) firewalls plus a connection allow-list so only authorized external networks can connect to the company network. Are these safeguards sufficient to meet the applicable CMMC requirement?
Applicable CMMC/NIST Requirement: AC.L2-3.1.20 --- ''Verify and control/limit connections to and use of external systems.''
Isolation Not Required (refutes B): The requirement acknowledges that individuals using external systems (e.g., contractors, partners) may need to access organizational systems. In such cases, organizations must ensure those connections do not compromise or harm organizational systems. Therefore, complete isolation from all external systems is not mandated.
Policy Alone is Insufficient (refutes A): Assessment guidance requires mechanisms that technically enforce terms and conditions for use of external systems. A written employee policy by itself does not satisfy the requirement unless paired with technical enforcement (e.g., firewalls, connection rules).
Allow-lists & Firewalls are Best Practice (supports C): Assessment considerations specify that organizations should restrict external systems to an approved list, such as by using firewalls, VPNs, IP restrictions, or certificates. The company's use of firewalls and a connection allow-list directly addresses this requirement.
Full Control of External Systems Not Required (refutes D): The definition of ''external systems'' clarifies that organizations typically do not have direct supervision or authority over those systems. The requirement is to limit and control connections to such systems, not to own or fully manage them.
Assessment Objectives for AC.L2-3.1.20 (from NIST SP 800-171A):
Connections to external systems are identified.
Use of external systems is identified.
Connections to external systems are verified.
Use of external systems is verified.
Connections to external systems are controlled/limited.
Use of external systems is controlled/limited.
Firewalls and allow-lists satisfy these verification and limitation requirements, enabling a CCA to mark the practice MET if evidence is present.
Reference (CCA Official Sources):
NIST SP 800-171 Rev. 2 --- 3.1.20 (Discussion)
NIST SP 800-171A --- 3.1.20 (Assessment Objectives & Methods)
CMMC Assessment Guide -- Level 2, Version 2.13 --- AC.L2-3.1.20 (External Connections [CUI Data], including ''Potential Assessment Considerations'')
A company receives data that they suspect is CUI, but it is not marked as such. What is an acceptable way for the company to handle unmarked potential CUI?
The CMMC Assessment Guide (Level 2) requires organizations to have a documented procedure for the identification and handling of unmarked potential CUI. The DoD guidance specifies that contractors cannot assume unmarked data is not CUI; instead, they must have a process to ensure unmarked potential CUI is handled properly until its classification is clarified.
Extract from Assessment Guide:
''Organizations must establish procedures for the handling of unmarked data that is suspected of being CUI. These procedures should define how unmarked information is protected until such time its status can be determined.''
Therefore, the correct answer is to have a procedure for proper handling of unlabeled data.
A company has a CUI enclave for handling all CUI processed, stored, and transmitted through the organization. While interviewing the IT manager, the CCA asks how assets that can, but are not intended to, handle CUI are identified. The IT manager refers to the CUI system's network diagram (which includes these assets) as well as the asset inventory (which lists these assets as Contractor Risk Managed Assets). Which other artifact MUST also mention these assets?
Contractor Risk Managed Assets (CRMA) are required to be identified in the System Security Plan (SSP) because the SSP must describe how each in-scope asset category is managed, including risk-based policies, procedures, and practices. Network diagrams and inventories alone are insufficient without documentation in the SSP.
Exact Extracts:
CMMC Scoping Guide: ''Contractor Risk Managed Assets are part of the CMMC Assessment Scope and must be identified in the OSC's SSP and supporting documentation.''
''The SSP must describe how the contractor manages risk for Contractor Risk Managed Assets.''
''The asset categories (CUI assets, Security Protection Assets, Contractor Risk Managed Assets, Specialized Assets) must be included in the SSP with supporting evidence.''
Why the other options are not correct:
A: Identification/authentication policy does not specifically require mention of CRMAs.
B: Physical protection policies address facility controls, not risk-managed assets.
C: Awareness training covers employees, not technical classification of assets.
D: Correct, because the SSP must explicitly document how CRMAs are managed using risk-based approaches.
CMMC Assessment Scope -- Level 2, Version 2.13: Asset categories and documentation requirements for CRMAs (pp. 6--10).
CMMC Assessment Guide -- Level 2, Version 2.13: SSP documentation requirements (pp. 12--14).
An OSC has an established password policy. The OSC wants to improve its password protection security by implementing a single change. Which of the following is an acceptable element to add to the OSC's password policy?
The Identification and Authentication (IA) practices require that passwords be protected using strong methods. Storing passwords with salted one-way hashes ensures they cannot be reversed, providing strong protection.
Extract from IA.L2-3.5.10:
''Passwords must be stored and transmitted in a form that is resistant to compromise, typically using salted one-way cryptographic hashes.''
Options A and B do not align with modern password guidance, and option C (two-way cryptographic hashing) is insecure because it allows reversal.
What should the Lead Assessor do to BEST ensure the evidence supplied effectively meets the intent of the standard for a practice?
The CAP defines evidence evaluation requirements. Evidence must not only exist but must also be:
Complete (addresses all assessment objectives for the practice)
Validated (verified by the assessor)
Mapped to the practice requirements (traceable to objectives)
Extract:
''The assessor must confirm that the evidence is complete, validated, and mapped directly to the practice requirements in order to conclude that a practice is MET.''
