DoD Assessment Scoring Methodology

[a] This scoring methodology is designed to provide an objective assessment of a contractor’s NIST SP 800-171/CMMC L2 Practice implementation status. Except for the practice for which the scoring of partial implementation is built-in (e.g., FIPS validated encryption, security requirement 3.13.11/CMMC Practice SC.L2-3.13.11) the methodology is not designed to credit partial implementation. However, partial credit can be applied for Derived Security Requirements that fall under practice SC.L2-3.13.11 - FIPS validated encryption, see paragraph “h” for additional guidance on partial credit for this practice based on how the practice is implemented.

[b] Conduct of the NIST SP 800-171 DoD Assessment Methodology on a CMMC L2 Assessments will result in a score reflecting the net effect of each CMMC Practice not yet implemented. If all CMMC practices are implemented, a contractor is awarded a score of 110, consistent with the total number of CMMC L2 Practices. For each CMMC Practice not met, the associated value is subtracted from 110. The score of 110 is reduced by practice not implemented, which may result in a negative score.

[c] While NIST SP 800-171 does not prioritize security requirements, certain requirements have more impact on the security of the network and its data than others. This scoring methodology incorporates this concept by weighting each security requirement based on the impact to the information system and the DoD CUI created on or transiting through that system when that requirement is not implemented.

[d] Weighted requirements include all of the fundamental NIST SP 800-171 ‘Basic Security Requirements’ - high-level requirements which, if not implemented, render ineffective the more numerous ‘Derived Security Requirements’; and a subset of the ‘Derived Security Requirements’- requirements that supplement the Basic Security Requirements - which, if not implemented, would allow for exploitation of the network and its information.

[e] For security requirements that, if not implemented, could lead to significant exploitation of the network, or exfiltration of DoD CUI, 5 points are subtracted from the score of 110. For example, failure to limit system access to authorized users (Basic Security Requirement 3.1.1/CMMC Practice AC.L1-3.1.1) renders all the other Access Control requirements ineffective, allowing easy exploitation of the network; failure to control the use of removable media on system components (Derived Security Requirement 3.8.7/CMMC Practice MP.L2-3.8.7) could result in massive exfiltration of CUI and introduction of malware.

i. Basic Security Requirements/CMMC Practices with a value of 5 points include AC.L1-3.1.1, AC.L1-3.1.2, AT.L2-3.2.1, AT.L2-3.2.2, AU.L2-3.3.1, CM.L2-3.4.1, CM.L2-3.4.2, IA.L1-3.5.1, IA.L1-3.5.2, IR.L2-3.6.1, IR.L2-3.6.2, MA.L2-3.7.2, MP.L1-3.8.3, PS.L2-3.9.2, PE.L1-3.10.1, PE.L2-3.10.2, CA.L2-3.12.1, CA.L2-3.12.3, SC.L1-3.13.1, SC.L2-3.13.2, SI.L1-3.14.1, SI.L1-3.14.2, and SI.L2-3.14.3.
ii. Derived Security Requirements with a value of 5 points include AC.L2-3.1.12, AC.L2-3.1.13, AC.L2-3.1.16, AC.L2-3.1.17, AC.L2-3.1.18, AU.L2-3.3.5, CM.L2-3.4.5, CM.L2-3.4.6, CM.L2-3.4.7, CM.L2-3.4.8, IA.L2-3.5.3, IA.L2-3.5.10, MA.L2-3.7.5, MP.L2-3.8.7, RA.L2-3.11.2, SC.L1-3.13.5, SC.L2-3.13.6, SC.L2-3.13.15, SI.L1-3.14.4, and SI.L2-3.14.6.

[f] For Basic and ‘Derived Security Requirements’ that, if not implemented, have a specific and confined effect on the security of the network and its data, 3 points are subtracted from the score of 110. For example, failure to limit access to CUI on system media to authorized users (Security Requirement 3.8.2/ CMMC Practice MP.L2-3.8.2) or failure to encrypt CUI stored on a mobile device (Security Requirement 3.1.19/CMMC Practice AC.L2-3.1.19), put the CUI stored on the system media or mobile device at risk, but not the CUI stored on the network itself.

i. Basic Security Requirements with a value of 3 points include AU.L2-3.3.2, MA.L2-3.7.1, MP.L2-3.8.1, MP.L2-3.8.2, PS.L2-3.9.1, RA.L2-3.11.1, and CA.L2-3.12.2.
ii. ‘Derived Security Requirements’ with a value of 3 points include AC.L2-3.1.5, AC.L2-3.1.19, MA.L2-3.7.4, MP.L2-3.8.8, SC.L2-3.13.8, SI.L1-3.14.5, and SI.L1-3.14.7.

[g] All remaining ‘Derived Security Requirements’, if not implemented, have a limited or indirect effect on the security of the network and its data. For these, 1 point is subtracted from the score of 110. For example, failing to prevent reuse of identifiers for a defined period (Security Requirement 3.5.5) could allow a user access to CUI to which they were not approved.

[h] ‘Derived Security Requirements’ can be partially effective even if not completely or properly implemented, and the points deducted should be adjusted depending on how the security requirement/practice is implemented.

i. FIPS validated encryption (CMMC Practice SC.L2-3.13.11) is required to protect the confidentiality of CUI. If encryption is employed, but is not FIPS validated, 3 points are subtracted from the score of 110; if encryption is not employed, 5 points are subtracted from the score of 110.

[i] Although not common, future revisions of NIST SP 800-171 and/or the CMMC Assessment Guide may add, delete, or substantively revise security requirements and CMMC Practices. When this occurs, a value will be assigned to any new or modified requirements in accordance with this scoring methodology.

[j] The contractor must have a system security plan (CMMC Practice CA.L2-3.12.4 ) in place to describe each covered contractor information system, and a plan of action (Practice CA.L2-3.12.2) in place for each unimplemented security requirement to describe how and when the security requirement will be met, not to exceed 180 days from the Assessment Final Recommended Findings Briefing (Phase 3).

(1) Since the NIST SP 800-171 DoD Assessment scoring methodology is based on the review of a system security plan describing how the security requirements are met, it is not possible to conduct the assessment if the information is not available. The absence of a system security plan would result in a finding that ‘an assessment could not be completed due to incomplete information and noncompliance with DFARS clause 252.204-7012.
(2) Plans of action addressing unimplemented security requirements are not a substitute for a completed requirement. Security requirements not implemented, whether a plan of action is in place or not, will be assessed as ‘not implemented.’ For example, if the initial roll-out of SC.L2-3.13.11, FIPS validated encryption , is only 75% complete due to vendor issues, and there is a plan of action still being implemented, SC.L2-3.13.11 will be considered ‘not implemented’, as the requirement has not been fully implemented.
(3) A lack of plan of action for unimplemented practices will result in CMMC Practice CA.L2-3.12.2 being assessed as ‘Not Met.’ During Phase 2 of the assessment process the OSC will populate CMMC Practice deficiencies on a POA&M to fulfill the objective level requirements for CMMC Practice CA.L2-3.12.2. Failure to generate an updated or complete POA&M document for the CMMC L2 assessment will result in CMMC practice CA.L2-3.12.2 being scored “NOT MET” and the CMMC L2 Interim Assessment Certification “Not Achieved.”

[k] Temporary deficiencies and/or isolated enduring exceptions which occur during initial implementation, or arise after implementation, are to be expected in most complex environments.

[l] Temporary deficiencies that are appropriately addressed in plans of action (i.e., include deficiency reviews, milestones, and show progress towards the implementation of corrections to reduce or eliminate identified vulnerabilities) should be assessed as ‘implemented.’ For example, when a plan of action addresses a ‘temporary deficiency’ that arises after implementation (e.g., SC.L2-3.13.11, employ FIPS validated cryptography, had been implemented, but subsequently a patch invalidated the FIPS validation of a particular cryptographic module), the requirement will be scored ‘as implemented.’ A ‘temporary deficiency’ may also arise during initial implementation of a CMMC practice if, during roll-out, specific issues with certain equipment is discovered that has to be separately addressed (e.g., certain specific hardware or software unexpectedly needs to be changed for the requirement to be successfully applied). If the implementation roll-out has otherwise been completed, this ‘temporary deficiency’ plan of action would be considered, and the requirement scored ‘as implemented.’ There is no standard duration for which a ‘temporary deficiency’ may be active. It is what is reasonable, which would take into consideration the availability of the solution, the cost and time to implement, the overall risk and whether any mitigations are applied in the Limited. Generally, deficiencies should be resolved as soon as is reasonably possible.

[m] Isolated enduring exceptions encountered during implementation, such as unique equipment or environments (e.g., specialized manufacturing equipment or a unique laboratory environment) may prevent the implementation of certain security requirements. Isolated enduring exceptions are typically not suitable to address in plans of action, but when described, along with any mitigations, in the system security plan such exceptions should be assessed as ‘implemented.’

[n] For certain requirements, questions often arise on whether or not they are actually implemented. These situations are addressed below:

(1) Practices AC.L2-3.1.12, AC.L2-3.1.16, AC.L2-3.1.18: Companies commonly do not allow remote access, wireless access or connection of mobile devices and may indicate these requirements as ‘Not Applicable’ or ‘Not Implemented’ in the system security plan. The evaluator (CMMC Assessor) should not deduct points in such cases. However, if the company disallows use of remote, wireless, or mobile access, they should also have a policy and procedure in place to ensure these capabilities are not enabled inadvertently. This should be discussed as part of Confirming the Assessment Outputs in paragraph 1.4.8, and if such policy and procedures are not in place a point should be assessed.
(2) CMMC Practice SC.L2-3.13.8: When implementing this requirement, encryption, though preferred, is not required if using common-carrier provided Multiprotocol Label Switching (MPLS), as the MPLS separation provides sufficient protection without encryption.
(3) CMMC Practice SC.L2-3.13.11: Cryptography used to protect the confidentiality of CUI must be FIPS-validated, which means the cryptographic module has to have been tested and validated to meet FIPS 140-1 or-2 requirements. Simply using an approved algorithm (e.g., FIPS 197 for AES) is not sufficient - the module (software and/or hardware) used to implement the algorithm must be separately validated under FIPS 140. Note however, that this is required when encryption is required for protection, which is typically external to the contractor's covered information system (assuming the system meets NIST SP 800-171/CMMC). Cryptography used for other purposes within the protected information system need not be FIPS validated. When required, if encryption is not employed (FIPS validated or otherwise), 5 points are subtracted from the score of 110. If encryption is employed, but is not FIPS validated, 3 points are subtracted from the score of 110. Isolated use of non-FIPS validated cryptography, with an associated Plan of Action, should be treated as a temporary deficiency and assessed as ‘implemented.’

[o] If a contractor received a favorable adjudication from the DoD CIO indicating that a requirement is not applicable or that an alternative security measure is equally effective in accordance with DFARS 252.204-7008 or 7012, the DoD CIO assessment should be included in the Contractor’s system security plan. Implemented security measures adjudicated by the DoD CIO as equally effective, and security requirements approved by the DoD CIO as ‘not applicable,’ will be assessed as ‘implemented.’ Once DOD CIO assessments approving “not applicable” requirements or “alternative security measures” are included in the Contractor's system security plan, the contractor does not need to submit that documentation for every current contract with the DFARS 252.204-7012 clause unless specifically requested to do so by the contracting officer. When completing the Basic (Contractor Self-Assessment) NIST SP 800-171 DoD Assessment Results Format, the contractor shall score any security requirements for which an assessment of “not applicable” or “alternative security measures” was previously approved by DoD CIO as ‘implemented’.

[p] A template illustrating the application of this scoring methodology is provided within this Appendix, paragraph K-2.

DoD Assessment Scoring Template

[a] The following template illustrates the scoring methodology described in section K-1. If all requirements are MET, a score of 110 is awarded. For each practice NOT MET, the associated value is subtracted from 110. Consistency results from the fact that the assessments are based on what is not yet implemented, or document that all requirements have been MET.

[b] It is important to note an assessment is about the extent to which the company has implemented the practices. It is not a value judgement about the specific approach to implementing – in other words, all solutions that meet the CMMC practices are acceptable. This is not an assessment of one solution compared to another.

[c] Scoring for Basic, Medium, and High NIST SP 800-171 DoD, and CMMC 3rd Party Assessments are all the same.

[d] While NIST does not prioritize requirements in terms of impact, certain requirements do have more impact than others. In this scoring methodology security requirements/ CMMC Practices are weighted based on their effect on the information system and DoD CUI created on or transiting that system.
