Cybersecurity Maturity Model Certification CMMC Requirements

Understand the Cybersecurity Maturity Model Certification (CMMC) Requirements

This guide is designed to help you understand the Cybersecurity Maturity Model Certification (CMMC) Requirements. This applies to CMMC Level 1, CMMC Level 2, CMMC Level 3, CMMC Level 4, CMMC Level 5, DFARS 7021, NIST800-171.

Who can use this CMMC Implementation Guide?

Any companies that need to implement CMMC for certification. Types of companies inlcude manufacturers, machine shops, DoD Contractors, Prime Subcontractors or third parties working with CUI data as part of their supply chain.

How can ChatFortress help you implement CMMC?

How to Implement a CMMC Audit/Assessment using CMMC Software Tool?

Here are the List of CMMC Requirements. You can choose from the list here for a more detailed explainer of what it means and how it applies.

We provide you with a CMMC Clarification- This is where we help you understand what this means and how it applies to your company. If you need further help, I'd recommend activating your ChatFortress Easy Compliance CMMC Assessment Tool because inside that tool; you will find more details on how to meet these CMMC Requirements.

CMMC Practice Requirement Questionnaire 

To help you understand the CMMC Gap Assessment I’m providing you with the list of CMMC practice requirements. When you visit www.ChatFortress.com/CMMCBook you will be provided with our Gap Assessment tool along with our detailed examples for each of the questions asked for CMMC. This helps you to understand the goal and application of each question. If you are reading the CMMC Practice Requirements and are confused that’s ok. Our team has translated the requirements into easy-to-understand and implement steps.

Note: Remember you need to satisfy the three elements for each of these questions 1. Documentation, 2. Systems & Processes, 3. Validation. As you read each requirement you might want to ask yourself the relevant questions about each requirement. CMMC is no longer self-assessment but validating to an auditor you are meeting each of the requirements.
