Dynamically Identifying and Redacting Data from Diagnostic Operations via Runtime Monitoring of Data Sources

Methods, systems, and computer program products for identifying and redacting data from diagnostic operations via monitoring of data are provided herein. A computer-implemented method includes automatically monitoring data, which includes determining which portions of the data are accessed during a diagnostic operation; parsing an input file into portions of parsed data, wherein the input file comprises an initial output of the diagnostic operation; classifying the portions of parsed data into classes by applying at least one of multiple classification models to the parsed data, wherein the at least one classification model is specific to the accessed portions of data; automatically identifying sensitive data in the classified portions of parsed data by applying a class-to-sensitivity mapping technique to the classified portions of parsed data; redacting the identified sensitive data from the input file; and generating and outputting an updated output of the diagnostic operation based on the redacting.
