    Overview of security features

    Last Updated: Mar 09, 2021

    This topic is intended for all owners and administrators of MaxCompute projects, and users who are interested in the MaxCompute multi-tenant data security system.

    MaxCompute provides a multi-tenant data security system, which has the following features:
    • User authentication
    • User and authorization management of projects
    • Cross-project resource sharing
    • Project data protection

    Limits

    • Limits on column-level access control
    • Limits on project data protection
    Previous: Enable security features Next: Add a user and grant permissions to the user
