Best Practices for Handling Sensitive Assessment InformationCMMC assessments involve handlingsensitive and potentially CUI-related documents. Assessors must follow strictsecurity policiesto avoid unauthorized access, data leaks, or non-compliance withCMMC 2.0 and NIST SP 800-171 requirements.

Why Logging into the Client VPN on the Client Laptop is the Best Approach:

Ensures Data Protection:The client laptop is likely configured to meet security controls required for handling assessment-related materials.

Prevents Data Spillage:Keeping all assessment-related activities within the client’s secured environment reduces the risk ofdata leakage or unauthorized storage.

Maintains Compliance with CMMC/NIST Guidelines:Using aproperly configured client laptop and secured connectionensures compliance withNIST SP 800-171 controls on secure remote access(Requirement3.13.12).

A. "Log into the secure cloud storage service to save copies of the documents on both the work and client laptops."

Incorrect→Sensitive data should not be duplicated across multiple systems, especially a non-client-approved laptop. Storing it on an unauthorized systemviolates data handling best practices.

C. "Log into the client VPN from the assessor's laptop and retrieve the documents from the secure cloud storage service."

Incorrect→ Theassessor’s laptop may not be authorizedorsecuredto handle client data. CMMC guidelines emphasizeusing approved, secured systemsfor assessment-related information.

D. "Use their home office workstation to retrieve the documents from the secure cloud storage service and save them to a USB stick."

Incorrect→

Transferring sensitive documents via USBintroduces security risks, including unauthorized data storage and potential malware contamination.

Home office workstationsare unlikely to be authorized for handling CMMC-sensitive data.
