Data protection plays a vital role in meeting CMMC (Cybersecurity Maturity Model Certification) compliance. CMMC is an information security standard that regulates the Defense Industrial Base (DIB). It aims to strengthen security measures for information transmission and use in the supply chain to ensure that confidential information is properly protected between contractors. Although the supply chain may not be directly related to national defense, it cannot avoid contractual constraints. When pursuing CMMC compliance, organizations should take a comprehensive approach that spans people, processes, and technology to build a resilient cybersecurity infrastructure that can adapt to evolving threats and protect confidential information.
