Data classification is a foundational practice in cybersecurity. It involves categorizing information based on its level of sensitivity and the impact that could result from its unauthorized disclosure.
By clearly labeling data types—such as public, internal, confidential, or regulated—organizations can apply appropriate security controls and avoid over- or under-protecting their information. This approach supports more efficient risk management and regulatory compliance.
For organizations working with the U.S. government or defense supply chain, one key category is Controlled Unclassified Information (CUI). CUI requires specific protections, even though it’s not classified at the top-secret level. Knowing where CUI resides and ensuring it is isolated from less sensitive data is essential.
A CMMC enclave can support data classification efforts by offering a secure, dedicated space to store and process CUI. These enclaves are designed to meet Cybersecurity Maturity Model Certification (CMMC) requirements and help businesses avoid mixing regulated and unregulated information.
Ultimately, good data classification enables smarter security decisions. It makes compliance easier, reduces unnecessary costs, and ensures that sensitive assets are treated with the attention they deserve.
