  • ROW-LEVEL PERMISSIONING BASED ON EVALUATED POLICIES
    Publication number: 20230306030
    Abstract: A computer system is disclosed that provides classification-based access controls at the dataset row-level. The system may perform operations including: ingesting a dataset, wherein the dataset comprises a table of rows and columns; determining a column of the table that includes permissions information; applying parsing rules to the column to determine, for each row of the table, a list of permissions markings; receiving, from a user, a request to access the dataset; and in response to receiving the request: determining a permissions policy associated with the user; determining an evaluated policy associated with the user based on the permissions policy; filtering the table based on applying the evaluated policy associated with the user to the permissions markings of each row of the table; and providing the user access to the filtered table.

  • ENFORCING SECURITY WITHIN A DATA PLATFORM
    Publication number: 20220414239
    Abstract: Computing systems and methods are provided for defining, within a data platform, a segment having constraints at a level of the segment, implementing the constraints or the classification rules within the segment while insulating resources within the segment from inheriting the constraints, and controlling an ingestion of an external resource into the segment based on the constraints.
