Attributes

Go To Naming Conventions

The ASP.NET MVC framework supports four different types of filters executed in the following order:

1. Authorisation filters – Implements the IAuthorizationFilter attribute.
2. Action filters – Implements the IActionFilter attribute.
3. Result filters – Implements the IResultFilter attribute.
4. Exception filters – Implements the IExceptionFilter attribute.

The common authorisation filters that is used in Signify are

• BypassModuleAuthorisation: The MVC authorization filter that enables one to by-pass module authentication.
• BypassSessionAuthorisation: The MVC authorization filter that enables one to by-pass session authentication.
• ModuleAuthorisation: Extended authorisation that determines if the user consists of a session.
• SecurityUserAuthorisation: Authorize the user against roles.
• Session Authorisation: Extended authorisation that determines if the user consists of a session, implemented in the base controller
• SystemAccessAuthorisation: Authorize the user on access to the module and the active status of the module.
