The ASA 5000 series adaptive security appliance includes a dedicated management interface called Management 0/0, which is meant to support traffic to the security appliance. However, you can configure any interface to be a management-only interface using the management-only command. Also, for Management 0/0, you can disable management-only mode so the interface can pass through traffic just like any other interface.
You can also add subinterfaces to the management interface to provide management in each security context for multiple context mode.
