## 11.4.2 JSecurity

JSecurity is another Java POJO oriented security framework that again provides a default domain model that models realms, users, roles and permissions. With JSecurity you have to extends a controller base called called `JsecAuthBase` in each controller you want secured and then provide an `accessControl` block to setup the roles. An example below:

    class ExampleController extends JsecAuthBase {
        static accessControl = {
            // All actions require the 'Observer' role.
            role(name: 'Observer')        // The 'edit' action requires the 'Administrator' role.
            role(name: 'Administrator', action: 'edit')        // Alternatively, several actions can be specified.
            role(name: 'Administrator', only: [ 'create', 'edit', 'save', 'update' ])
        }    …
    }
