CSG-AutoSuspendUntrustworthyClientAccess

Access to service Service by client Client may be automatically disabled to prevent authenticated attacks by compromised clients, 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.

CSG-AutoSuspendUntrustworthyClientAccess-Implementation-Runtime

Access to service Service by client Client has been automatically disabled to prevent authenticated attacks by compromised clients. 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.

CSG-StaffScreening

Persons fulfilling the role Human are screened by their employer Employer before being given that role. This ensures they are more trustworthy than one would expect given the population or community they come from.

Access to service Service by client Client may be temporarily disabled by the process manager ServiceManager to prevent authenticated attacks by compromised or impersonated clients, at the cost of some reduction in availability. This strategy represents a contingency plan, which can be used to reduce risk from some threats. However, it also triggers other threats representing side effects of the policy change, based on how likely it is that the contingency plan will need to be activated.
