A user or user group associated with an access control list

An access control list describes the relationship between users (and user groups) and an access controllable item, such as a survey or report, detailing what permissions each user or group has with respect to the item.

The permissions associated with a particular user or group in an access control list for an item

Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML. The CSS specifications are maintained by the World Wide Web Consortium (W3C).

The permission policy that applies to users not explicitly in the access control list for an item

The ability of a user to perform a discreet task, e.g. “Form.Fill” (complete a survey) or “Analysis.Responses.View” (view the individual responses to a survey). Permissions are the smallest unit of access control within Checkbox Web. Changing the particular permissions for a user, role, or policy is rarely needed, and should only be attempted by advanced users.

A logical grouping of permissions with an easily understandable name. For example: the permissopn mask "Administer Survey" includes the permissions: Form.Fill, Form.Create, Form.Delete, Form.Edit, and Form.Fill

A user known to Checkbox Web (either by being added directly, or by being imported from another system) for the purposes of controlling access to areas of the application or items created in the application (e.g. surveys, reports, etc.)

A logical grouping of a set of permissions assigned to a user. A role can be thought of the collection of actions a user in that role can take. For example, a user who is in the Respondent role has the Take Survey permission, as that is the only permission associated with that role.
