Cybersecurity Maturity Model Certification advisory services

Supporting government contractors throughout their CMMC compliance journey

Defense contractors and the entire government contracting supply chain are facing complex cybersecurity regulatory expectations, made increasingly complicated by external threat actors attempting to gain unauthorized access to controlled unclassified information (CUI) and other federally regulated sensitive data. In response to the increased need for adequate protection, the Department of Defense (DOD) released the Cybersecurity Maturity Model Certification (CMMC) to enhance and enforce cybersecurity expectations across the defense industrial base (DIB).

RSM offers an array of services designed to help government contractors at any stage of their CMMC compliance journey. Our advisory services are tailored to each organization seeking certification (OSC) to assist with defining, implementing and maintaining their compliant environment.

Preparing for the CMMC journey

We know that achieving and maintaining compliance with the CMMC requirements can be challenging. Our advisory services help contractors identify their compliance obligations and validate the flow of CUI internally and externally while minimizing the scope and rightsizing their cybersecurity program. Related services we offer include:

Data identification

CUI identification and boundary definition

Our team assists organizations with identifying the collection, use, processing and storage of CUI. This includes determining the flow of CUI and guiding OSCs in customizing their authorization boundary or rationalization to reduce overlapping applications.

Readiness

Readiness/gap assessment

In this point-in-time assessment, we identify operational and technological gaps and improvement opportunities across the governance model (e.g., policies and procedures) and assist in creating a plan of action and milestones. The result is a strategic road map to achieve CMMC compliance. Estimated risk ratings of the processes, capabilities and technology in each functional area aid management in developing and submitting scores to the DOD Supplier Performance Risk System.

Program management

Cybersecurity program management

RSM will assist OSCs with designing, implementing and managing improvements that optimize and support a client’s CMMC compliance program and cybersecurity posture, including creating customized authorization boundary, designing data flow diagrams, aiding in CUI data identification / labeling, developing a system security plan, and documenting underlying cybersecurity policies and standard operating procedures.

Penetration testing

CUI segmentation penetration testing and ‘red team’ assessment

We utilize best-in-class industry methodologies, tools and techniques to assess the maturity of your cybersecurity program and posture, identifying possible attack vectors, vulnerabilities and threats that may pose a significant risk to your organization. Based on our detailed findings, we develop a road map to improve your security program and reduce risk exposure.

CMMC implementation and remediation services

Alignment of existing technology with the CMMC requirements can be difficult to implement and maintain, but compliance is required to continue doing business with the federal government and DOD supply chain. RSM offers comprehensive infrastructure transformation and implementation services to help government contractors maintain an effective cybersecurity posture that mitigates the risks of today’s threat landscape.

Our team’s first step in meeting your organization's CMMC requirements is to understand the current boundary of the CUI environment and how CUI flows through the technology environment. We then determine whether to secure the authorization boundary as is or design and implement a separate, secure enclave isolated from the broader enterprise.

Technical review

Technical review

RSM performs technical reviews of your in-scope CUI assets to facilitate technical alignment with the requirements of NIST 800-171 (a special publication of the National Institute of Standards and Technology). Through this process, organizations gain a thorough understanding of their technical compliance status and create a plan to address any gaps.
