Practices found in CMMC Levels 1-3 called out an aggregated 130 Practices and 51 Processes that lead to Level 3 compliance. Level 4 specifically includes 26 additional technical practices derived from multiple sources such as NIST 800-171, CERT Resilience, CIS Controls v7.1, and more. See the Practices and Processes below:
Scott Edwards, President of Summit 7 and national security/compliance speaker, spoke on the importance of the Incident Response (IR) Domain and stated "Incident Response is something that I almost want to call the core of CMMC Level 4".
Upon CMMC Level 3 compliance, or the implementation of the appropriate 130 Practices, you'll need to implement the additional 26 shown in the accordion section above.
A few ways to meet new practices and additional resourcing requirements (software, hardware, personnel, outsourcing) are:

Summit 7 has architected a solution set to help organizations achieve CMMC Level 4 compliance that is developed for Office 365 GCC High and Azure Government. To discuss with our team and develop your roadmap for Level 4, complete the form below.
As the image below details, Level 4 requires organizations to practice "Proactive Cyber Hygiene", while having "reviewed" security processes and methods for "reducing risk of Advanced Persistent Threats (APT)s and increasing protection of CUI". For contractors in the DoD, Level 4 compliance may be more uncommon than Level 3, as it will be contractually required far less in RFPs and is seen as more of a transitional step to Level 5. It is also an increase in responsibility and likely cost. Levels are cumulative, meaning a Level 4 certified organization will need to meet the practices found in Levels 1, 2, 3, and 4.
