3.1.14Funnel remote access through known entry points in Rev. 3
Withdrawn and incorporated elsewhere: 03.01.12 Remote Access.
Status as of 2026-09-08
Rev. 2 is what a contract requires today. DFARS 252.204-7012 and the CMMC rule at 32 CFR 170 point at NIST SP 800-171 Rev. 2, and a standing DoD class deviation keeps it there. NIST has published Rev. 3, but publishing a revision does not change an obligation. A move to Rev. 3 would arrive through the Department's reform process and formal rulemaking, a change to that deviation or an amendment to the rule, not through publication. The Department has published its organization-defined parameter values for Rev. 3 in preparation; that is groundwork, not adoption.

NIST's Rev. 3 discussion for 03.01.12
Remote access is access to systems (or processes acting on behalf of users) that communicate through external networks, such as the internet. Monitoring and controlling remote access methods allows organizations to detect attacks and ensure compliance with remote access policies. Routing remote access through managed access control points enhances explicit control over such connections and reduces susceptibility to unauthorized access to the system, which could result in the unauthorized disclosure of CUI. Remote access to the system represents a significant potential vulnerability that can be exploited by adversaries. Restricting the execution of privileged commands and access to security-relevant information via remote access reduces the exposure of the organization and its susceptibility to threats by adversaries. A privileged command is a human-initiated command executed on a system that involves the control, monitoring, or administration of the system, including security functions and security-relevant information. Security-relevant information is information that can potentially impact the operation of security functions or the provision of security services in a manner that could result in failure to enforce the system security policy or maintain isolation of code and data. Privileged commands give individuals the ability to execute sensitive, security-critical, or security-relevant system functions.
What this means for you now
Nothing changes in what you are assessed against until a class deviation or a published rule adopts Rev. 3. Keep meeting 3.1.14 as written in Rev. 2.
Bedrock CMMC shows this same comparison against your own package, with your current status on the Rev. 2 side, so the day adoption lands the migration is a review, not a rewrite.
