  • receiving a query requesting data from a database;

    determining whether the query is anomalous;

    if the query is not anomalous, classifying the query as legitimate;

    if the query is anomalous, determining whether the anomaly is due to a change in the database by determining whether a label used in the query is in a set of labels that are used by legitimate database queries; and

    if the anomaly is due to a change in the database, classifying the query as legitimate.
