  • Publication number: 20230205755
    Abstract: Methods and systems are provided for enhanced data loss prevention. Data loss prevention may be applied to data that includes a plurality of records and a plurality of categories, with each record including a plurality of fields and each field corresponding to a different one of the categories. Applying of data loss prevention may include selecting a subset of records from the plurality of records; scanning fields of the selected subset of records for sensitive information; computing based on a result of the scanning, for each category, a likelihood the category contains the sensitive information; selecting a subset of categories based on the computed likelihoods of the categories to contain the sensitive information; searching the sensitive information in the selected subset of categories; and in response to detection of sensitive information in at least one of the subset of records, taking one or more data loss prevention related actions.

  • Patent number: 11609897
    Abstract: Methods and systems are provided for enhanced data loss prevention. The enhanced data loss prevention may be applied to data that is structured and/or semi-structured data, with the data comprising a plurality of records and a plurality of categories, with each record comprising a plurality of fields, each of which being associated with a different one of the plurality of categories. The enhanced data loss prevention may comprise selecting a subset of records of the data, with the selected subset comprising at least two records having between then one or more records not included in the subset. The fields of the selected subset may be scanned for sensitive information, and a likelihood to contain the sensitive information may be computed for each category based on the scanning. A subset of categories may be selected based on the computed likelihoods, and the sensitive information in the selected subset may be searched.
