Control Strategy AutoSuspendExcessiveClientAccess.Implementation

URI: CSG-AutoSuspendExcessiveClientAccess-Implementation-Runtime

Package: CloudManagement

< prev | next >

Description: Access to service Service by client Client has been automatically disabled to prevent the service forwarding excessive requests or becoming overloaded itself. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. Activation at runtime requires Service to be managed by a suitable adaptation framework. The Disable Client Access control should be deselected if and when access by Client to Service has been enabled once again.
