Control Strategy AutoSuspendExcessiveClientAccess

URI: CSG-AutoSuspendExcessiveClientAccess

Package: CloudManagement

< prev | next >

Description: Access to service Service by client Client may be automatically disabled to prevent the service forwarding excessive requests or becoming overloaded itself, at the cost of some reduction in availability. This strategy represents a contingency plan, which can be used to reduce risk from some threats but it also triggers other threats representing possible side effects, depending on how likely it is that the contingency plan will need to be activated.
