Who Should Take This

It is intended for Certified Cybersecurity Professionals (CCP) who serve as assessment team members and need formal authorization to perform CMMC Level 2 assessments. These learners typically have several years of information‑security experience, familiarity with NIST 800‑171, and seek to deepen their expertise in CMMC scoping, process execution, and practice validation.

Course Outline

1Domain 1: Evaluating Organizations Seeking Certification
2 topics

Organizational readiness evaluation

  • Evaluate organizational readiness for CMMC Level 2 assessment by reviewing system security plans, network diagrams, and CUI data flow documentation.
  • Analyze organizational security posture to identify potential gaps between current control implementations and CMMC Level 2 requirements.
  • Apply pre-assessment evaluation techniques to verify that the organization has adequate documentation, personnel availability, and system access for assessment execution.
  • Apply the CMMC scoping guidance to determine OSC (organization seeking certification) boundary, including FCI/CUI flow analysis.
  • Apply the CMMC scoping guidance to determine OSC (organization seeking certification) boundary, including FCI/CUI flow analysis.

System security plan assessment

  • Evaluate system security plan completeness by verifying that all 110 security requirements are addressed with specific implementation descriptions.
  • Apply assessment techniques to verify that SSP descriptions accurately reflect actual system configurations, policies, and operational procedures.
  • Analyze POA&M entries to evaluate remediation timelines, resource allocations, and milestones for conditional certification eligibility determination.
  • Examine an OSC's System Security Plan (SSP) and POA&M for completeness against NIST SP 800-171 controls.
  • Examine an OSC's System Security Plan (SSP) and POA&M for completeness against NIST SP 800-171 controls.
2Domain 2: CMMC Level 2 Assessment Scoping
1 topic

Advanced scoping techniques

  • Apply advanced scoping techniques for complex CUI environments including multi-enclave architectures, cloud-hosted enclaves, and geographically distributed systems.

  • Analyze external service provider relationships to determine assessment boundary inclusions and inheritance of security requirements.
  • Design assessment scope validation procedures to confirm that all CUI data flows, processing locations, and storage repositories are captured within assessment boundaries.
  • Identify the asset categories within CMMC scope (CUI assets, security protection assets, contractor risk-managed assets, specialized assets, out-of-scope assets).
  • Construct a scoping recommendation for an OSC with mixed cloud and on-premises infrastructure.
  • Examine CUI flow diagrams and recommend boundary refinements that minimize assessment scope without compromising compliance.
  • Identify the asset categories within CMMC scope (CUI assets, security protection assets, contractor risk-managed assets, specialized assets, out-of-scope assets).
  • Construct a scoping recommendation for an OSC with mixed cloud and on-premises infrastructure.
  • Examine CUI flow diagrams and recommend boundary refinements that minimize assessment scope without compromising compliance.
3Domain 3: CMMC Assessment Process
2 topics

Assessment planning and execution

  • Apply assessment planning procedures to develop detailed assessment schedules, evidence request lists, and interview plans for CMMC Level 2 assessments.
  • Apply assessment interview techniques to elicit relevant information from organizational personnel about security control implementation and operational procedures.
  • Evaluate evidence sufficiency by determining whether collected documentation, interview responses, and technical observations adequately support scoring decisions.
  • Apply the CAP (CMMC Assessment Process) phases (planning, conducting, reporting) to an upcoming Level 2 assessment.
  • Apply the CAP (CMMC Assessment Process) phases (planning, conducting, reporting) to an upcoming Level 2 assessment.

Scoring and reporting

  • Apply CMMC scoring methodology consistently across all practices to determine Met, Not Met, and Not Applicable results with documented justification.
  • Analyze scoring results to determine overall assessment outcome including certification recommendation, conditional certification, or certification denial.
  • Design comprehensive assessment reports that clearly document findings, scoring rationale, deficiency descriptions, and recommendations for remediation.
  • Examine common assessment scenarios (test, examine, interview methods) and recommend the appropriate evidence-collection method per practice.
  • Examine common assessment scenarios (test, examine, interview methods) and recommend the appropriate evidence-collection method per practice.
4Domain 4: Assessing CMMC Level 2 Practices
5 topics

Access control and identification assessment

  • Evaluate access control practice implementations including account management, access enforcement, remote access, and wireless access controls against CMMC Level 2 requirements.
  • Apply assessment techniques for identification and authentication practices including MFA implementation, authenticator management, and replay-resistant authentication.
  • Analyze personnel security and awareness training implementations to assess hiring practices, access agreements, and role-based security training adequacy.
  • Identify the 14 NIST SP 800-171 control families and the 110 practices CMMC Level 2 inherits.
  • Identify the 14 NIST SP 800-171 control families and the 110 practices CMMC Level 2 inherits.

System protection and communications assessment

  • Evaluate system and communications protection practices including boundary protection, CUI encryption in transit and at rest, and session management controls.
  • Apply assessment techniques for system and information integrity practices including flaw remediation, malicious code protection, and security alert monitoring.
  • Evaluate configuration management and maintenance practices including baseline configurations, change control, system maintenance controls, and maintenance personnel oversight.
  • Apply MET, NOT MET, and NOT APPLICABLE scoring to a sampled control during assessment.
  • Apply MET, NOT MET, and NOT APPLICABLE scoring to a sampled control during assessment.

Audit, incident response, and risk assessment

  • Evaluate audit and accountability practice implementations including audit event generation, analysis, storage protection, and correlation across system components.
  • Apply assessment techniques for incident response practices including incident handling, reporting, response testing, and incident monitoring capabilities.
  • Evaluate risk assessment and security assessment practices including vulnerability scanning, risk management, and security assessment planning and execution.
  • Design integrated practice assessment strategies that efficiently evaluate interdependent security requirements across multiple NIST SP 800-171 families.
  • Construct an assessment finding (Met/Not Met) with supporting rationale and references to specific evidence.
  • Construct an assessment finding (Met/Not Met) with supporting rationale and references to specific evidence.

Media and physical protection assessment

  • Evaluate media protection practices including CUI media marking, storage, transport, sanitization, and disposal controls for physical and digital media.
  • Apply assessment techniques for physical protection practices including physical access controls, visitor management, and environmental protection measures.
  • Evaluate recovery and contingency planning practices including system backup, information system recovery, and alternate processing capabilities for CUI environments.

Practice-Specific Methodology

  • Identify the highest-frequency assessment objectives across the 110 practices and the typical evidence types each requires.
