| Group Permissions |
Specify the group to which this policy applies. To designate the group as an Administrator for the chosen resource, specify Admin privileges. (Administrators can create child policies based on existing policies). |
| User Permissions | 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). |
| Enable/Disable | Policies are enabled by default. To restrict user or group access to the policy, select Disable. |
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
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.
To assign user privileges or roles, complete the User and Group Permissions portion of the Storm Create Policy form.
