Fingerprint data ?

Regex causes many false positive so we don't block,  heard that 'fingerprinting' data is the way to go.  How has fingerpinting worked for anyone in the community?

    Your RegEx needs to be created based on your company's business requirements.

    Are you seeing false positives

    1. across all rules or is it limited to certain rules only?

    2. for all data types or is it limited to certain data types only?

    For source code or any data that could be dynamic in nature, use RegExes.

    It is not easy since the code varies depedning on the programming language.

    If the Data Protection process was followed per standards i.e. Data Identification and Inventory was completed before DLP deployment you wouldn't have issues knowing what to look for.

     

    For static data, in your example, account number + last name, fingerprinting would be the best option. You can create RegExes for account number, but not for any name.

    My previous reply still holds good for your questions.

    Other than RegExes, since you mentioned that the users are not classifying data properly, to me it sounds like they need to be trained better.

    Yes. You can fingerprint using NDLP.
