Things to Keep in Mind When Starting Your CMMC Assessment

The congressional obligation to decrease the risk of accidental exposure of controlled unclassified information is one of the key motivations of the Cybersecurity Maturity Model Certification. A thorough CMMC consulting and evaluation, on the other hand, might appear intimidating to firms in the Defense Industrial Base (DIB), and many may not know where to begin.

Here, we have listed actions for DIB firms to determine their CUI risk in terms of vital services and the assets that support them. This methodology can assist DIB organizations in appropriately scoping a CMMC evaluation and reducing the expenses of CUI protection.

Identify Critical Services

Begin by concentrating on the business solutions that are vital to your customer. Mark the items or services your business makes to assist your customers and partners in carrying out their goals. Accepting and fulfilling orders from business partners is one crucial business function. Because you require it to suit the demands of your business partner, your B2B Order Portal would be the main emphasis for this service. Obviously, this component is backed by a plethora of internal services that aid in supplying resources to customers.

It is possible to determine an organization’s essential services by evaluating its mission statement and then correlating the services that acknowledge the mission. Organizations may have already gone through this process and will only need to look at their most recent BIA. A well-executed BIA will identify the most important services supplied to consumers and partners alike.

Define Organizational Assets

Technology: Technology refers to the hardware and software that power your essential services, which may include services offered by a cloud service provider (CSP) or managed (security) service providers (MSP/MSSP).

Information: Specifically, the data generated by your vital services, such as product schematics, customer information, order information, and so on.

People: Those individuals (including your supplier chain) who are in charge of the functioning of your vital services.

Facility: A physical structure that houses any of the other three asset types that support your critical service.

Scope Your Critical Services

The process of scoping a critical service includes determining the assets that enable it, such as software, data, personnel, and infrastructure. You’ll then know which assets are included in the service and which are not.

A data flow diagram, similar to those used in threat modeling, is one of the most valuable tools for this purpose. A data flow diagram comprises the four asset categories stated above, arranged in the sequence in which a vital service consumes them. 

Applying CMMC standards and procedures across areas of the business not controlled by CMMC compliance, on the other hand, may surpass the business needs of your other efforts in terms of time, budget, and resources for medium, large, and even multi-national firms.

These firms should assess the utilization of organizational assets throughout their lines of business to determine whether the broad application of CMMC is viable. The procedures outlined above offer these businesses a manageable method for assessing the extent of their CMMC evaluation.
