When the recently released CMMC Interim Rule (DFARS Case 2019-D041) takes effect on November 30, 2020, the Department of Defense (DoD) will require defense contractors to self-report a score of compliance with 800-171 controls using a specified scoring methodology. The new assessment methodology consists of 3 levels:
|Basic||Self-assessment performed by the contractor based on review of the System Security Plan (SSP) conducted in accordance with NIST SP 800-171A. DoD is encouraging contractors to immediately conduct and submit a Basic Assessment.|
|Medium||DoD assessment consisting of a thorough review of the SSP and discussions for additional information and clarification. DoD plans to select 200 contractors for Medium Assessments each fiscal year from FY 2021-2023.|
|High||DoD assessment consisting of a thorough document review and thorough verification/examination/demonstration by reviewing appropriate evidence to validate implementation of security requirements matches the SSP DoD plans to select 110 contractors for High Assessments each fiscal year from FY 2021-2023.|
Contractors must submit self-assessment results to the Supplier Performance Risk System (SPRS) for contracting agencies to evaluate. Contractors not listed on the SPRS will not be eligible for contracts. Only contractors that have a current (not older than 3 years) DoD 800-171 Assessment score can be considered for awards involving Controlled Unclassified Information (CUI). DoD is rolling out this new 800-171 self-assessment over the next 3 years (FY 2021-2023) as an interim step toward CMMC compliance which is targeted for the next 7-10 years.
The methodology uses a scoring system to rate a contractor’s implementation of required security controls. As with prior 800-171 self-assessments, each system must be defined by a System Security Plan (SSP) with a Plan of Actions and Milestones (POAM) for tracking specific measures to be taken to fully implement required controls. A contractor starts with 110 points and then subtracts 1-5 points for each requirement that is not fully and properly implemented. Failure to implement significant controls will result in a negative score. Points to subtract are weighted as follows:
|Each unimplemented 800-171 control that protects against “significant exploitation of the network or exfiltration of DoD CUI” (42 controls)||
Each unimplemented 800-171 control with “specific and confined effect on the security of the network and its data” (14 controls)
|Each unimplemented 800-171 control with “limited or indirect effect on the security of the network and its data” (remaining controls)||
Importantly, the CMMC Interim Rule eliminates most allowances for partial implementation of controls. There is no credit for partial implementations, apart from a few exceptions documented in the CMMC Interim Rule or for specific requirements previously submitted in writing to DoD and approved by DoD.
