What Is CMMC Maturity Level 2

The Cybersecurity Maturity Model Certification (CMMC) Level 2 in CMMC 2.0 replaces Level 3 in CMMC 1.0, which called for processes to be managed and controls qualified as good cyber hygiene. CMMC Level 2 (Advanced) is a requirement for organizations that want to want to bid on U.S. Department of Defense (DoD) contracts which handle the following types of information.

  • Controlled Unclassified Information (CUI)/Controlled Defense Information (CDI)
    CUI is a broad category of information the U.S. government or an entity acting on behalf of the government creates or possesses that needs to be safeguarded against misuse or abuse. The term CDI is used, interchangeably, by the DoD to describe CUI.
  • Controlled Technical Information (CTI)

CTI is technical information with military or space application that is subject to controls on the access, use, reproduction, modification, performance, display, release, disclosure, or dissemination.  

  • Export-Controlled Information (ECI)

Export-Controlled Information includes information regulated for national security, foreign policy, anti-terrorism, or non-proliferation reasons. This type of data is governed by  International Traffic in Arms Regulations (ITAR), and Export Administration Regulations (EAR).

CMMC Level 2 compliance establishes robust controls to prevent data breaches and other illegal access.

CMMC Level 2 is also mandatory for contracts that include the DFARS 252.204-7012 requirement.

CMMC Level 2 focuses on cyber hygiene and enhanced defenses against cyber threats. The process maturity element is also introduced at CMMC Level 2. To achieve certification for CMMC Level 2, an organization must perform and document extensive cybersecurity capabilities.

Compared to CMMC Level 1, which consists of 15 FAR 52.204-21 requirements, CMMC Level 2 requires organizations to satisfy all 110 security controls from NIST SP 800-171. CMMC Level 2 builds upon the core security practices that are established in Level 1 and is designed to bolster the overall security of the organization. As a result, CMMC Level 2 is a considerable step up from CMMC Level 1 in terms of complexity, timeline, and cost.

CMMC Level 2 Processes

The maturity processes of CMMC measure the degree to which an organization has institutionalized its cybersecurity practices. CMMC Level 2 maturity processes are categorized as Documented. At CMMC Level 2, organizations are required to put policies in place that reflect the objectives and importance of the practices that are included in required domains. 

Process documentation for CMMC Level 2 policies should include:

  • Definition of the scope of the policy (e.g., enterprise-wide, department-wide, information-system specific)
  • Description of the roles and responsibilities of the activities covered by this policy (i.e., the responsibility, authority, and ownership of domain activities)
  • Guidance for each of the 17 practice domains
  • Message from senior management that:
    • Articulates expectations for planning and performing the activities 
    • Communicates those expectations to the broader organization
    • Demonstrates that senior management sponsors and oversees the domain activities
  • Procedures to carry out and meet the intent of the policy, including any regulatory guidelines the policy addresses
  • Statement of the purpose of the policy

The objectives of CMMC Level 2 process policies are to:

  • Achieve expected outcomes
  • Enable an organization to execute the CMMC practices in a repeatable manner. 
  • Establish a foundation for continuous improvement.

How Can Your Organization Meet CMMC Level 2 Assessment Objectives?

The CMMC Level 2 certification process is conducted by a Cyber-AB CMMC Third-Party Assessment Organization (C3PAO). Once finalized, an assessment remains valid for three years from the assessment certification. 

Understanding CMMC Level 2 assessment procedures is critical to meeting the requirements. Assessment procedures consist of an associated set of methods and objects for each assessment objective. C3PAOs evaluate objectives by applying a method to an assessment object. CMMC Level 2 assessment objects identify items within the scope of the objective, including:

  • Activities
    These are protection-related actions for people who support information systems, such as

conducting system backup operations and monitoring network traffic.

  • Mechanisms 

These are specific hardware, software, or firmware safeguards used within an information system.

  • Specifications
    These are document-based artifacts associated with an information system, such as policies, procedures, plans, specifications, and designs.

Assessors will use several assessment methods to evaluate each assessment objective, including requirements to:

  • Examine
    Review documents, such as policies, procedures, plans, diagrams, inventories, configurations, rule sets, and system logs.
  • Interview
    Talk with key individuals to facilitate understanding, achieve clarification, or identify the location of evidence.
  • Test
    Directly work with systems and networks to identify vulnerabilities and measure levels of compliance in areas such as configuration or patch management and password policy.

Following is an outline of the CMMC assessment process at a high level:

  • Organization Seeking Certification (OSC) submits documentation to the assessment team
  • Kick-off meeting to review scope, schedule, and process
  • Security Assessment Plan drafted to define the assessment steps and identify proposed tools and review techniques 
  • Rules of Engagement created to define the proposed steps for the assessment, including outside testing, interview conduct, and inspection requirements
  • Security Assessment Plan and Rules of Engagement approved
  • Assessment conducted
  • Key personnel interviewed
  • Processes and security controls observed in action 
  • Security walk-through conducted
  • Systems tested with tools defined in Security Assessment Plan
  • Findings reviewed with the OSC for interpretation and evaluation to remove any “false positives” that are externally mitigated 
  • Security Assessment Report drafted 
  • Security Assessment Report reviewed with the OSC for final remediation 
  • Certification recommendation delivered with the Security Assessment Report

Uplevel Security and Continuously Improve with CMMC Level 2

While CMMC Level 2 is an arduous undertaking, it remains a mandatory hurdle for organizations that want to bid on Department of Defense (DoD) contracts. But, it brings significant cyber-preparedness benefits to organizations that adhere to its requirements. 

CMMC Level 2 compliance establishes robust controls to prevent data theft, unauthorized system access, and other illegal activities that can harm not just DoD agencies, but the organizations that serve them. With CMMC Level 2 compliance, organizations have assurances that their cybersecurity plan involves continuous monitoring and upgrading to thwart potential cyber-attackers who act with malicious intent.
