Table 5.3. Policy Details
Label
Description
Policy Name Enter an appropriate policy name. This name is cannot be duplicated across the system. This field is mandatory. Storm Topology Enter an appropriate Topology Name. Description (Optional) Describe the purpose of the policy. Audit Logging Specify whether this policy is audited. (De-select to disable auditing). Table 5.4. Allow Conditions
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).
The public group contains all users, so granting access to the public group grants access to all users.
Select User Specify 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). Permissions Add or edit permissions: Read, Write, Create, Admin, Select/Deselect All. Delegate Admin When 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 Storm does not provide a command line methodology for assigning privileges or roles to users, the User and Group Permissions portion of the Storm Create Policy form is especially important.
