Data-centric monitoring is a security approach that focuses on sensitive information and the activity surrounding it: who or what accesses the data, when access occurs, and how the information is used or moved. It puts the data itself-not only users, devices, or network events-at the center of monitoring.
This approach helps defenders identify risks such as unusual access to confidential files, excessive permissions, or unexpected data transfers. In practice, monitoring may use access logs, data classifications, and behavioral baselines to distinguish routine work from suspicious activity. It is most useful when sensitive data is clearly identified and access patterns are understood; otherwise, alerts may lack context or overwhelm analysts.
