what is windows azure appfabric access control service
Access Control Service Access Control Service, or Windows Azure Access Control Service (ACS) is a Microsoft-owned cloud-based service that provides an easy way of authenticating and authorizing users to gain access to web applications and services while allowing the features of authentication and authorization to be factored out of the application code.[1] This facilitates application development while at the same time providing users the benefit of being able to log into multiple applications with a reduced number of authentications, and in some cases only one authentication. The system provides an authorization store that can be accessed programmatically as well as via a management portal. Once authorizations are configured, a user coming to an application via ACS arrives at the application entrance with not only an authentication token, but also a set of authorization claims attached to the token.
Fire alarm control panel A fire alarm control panel (FACP), fire alarm control unit (FACU), or simply fire alarm panel is the controlling component of a fire alarm system. The panel receives information from devices designed to detect and report fires, monitors their operational integrity and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also supply electrical energy to operate any associated initiating device, notification appliance, control, transmitter, or relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems.
