What is Data Classification in Cybersecurity?
The process of categorizing data based on its sensitivity, regulatory requirements, and the impact that unauthorized disclosure would cause. Common classification levels include public, internal, confidential, and restricted. Data classification drives decisions about encryption, access controls, storage locations, retention periods, and breach notification requirements for each data category.
Why Data Classification Matters for Your Cybersecurity Career
You cannot protect data you have not classified. Data classification is the foundation of every data protection program. GRC analysts develop classification policies and train employees on proper handling. Security engineers implement automated classification tools and technical controls for each level. CISOs use classification to prioritize security investments on the most sensitive data.
