    Table 5.9. Policy Details

    FieldDescription
    Policy NameEnter an appropriate policy name. This name cannot be duplicated across the system. This field is mandatory.
    Knox TopologyEnter an appropriate Topology Name.
    Knox ServiceEnter an appropriate Service Name.
    Description(Optional) Describe the purpose of the policy.

    Table 5.10. User and Group Permissions

    Label

    Description

    Select Group Specify the group to which this policy applies. To designate the group as an Administrator for the chosen resource, specify Admin permissions. (Administrators can create child policies based on existing policies).
    Select UserSpecify a particular user to which this policy applies (outside of an already-specified group) OR designate a particular user as Admin for this policy. (Administrators can create child policies based on existing policies).
    Policy ConditionsSpecify IP address range,
    PermissionsAdd or edit permissions: Read, Write, Create, Admin, Select/Deselect All.
    Delegate AdminWhen a policy is assigned to a user or a group of users those users become the delegated admin. The delegated admin can update, delete the policies. It can also create child policies based on the original policy (base policy).


    Since Knox does not provide a command line methodology for assigning privileges or roles to users, the User and Group Permissions portion of the Knox Create Policy form is especially important.

    Wild cards can be included in the resource path, in the database name, the table name, or column name:

    • * indicates zero or more occurrences of characters

    • ? indicates a single character

  4. Click Add.
