predictable failure prevention  | manual transfer between components

assessment objective:

Determine if the organization:

si-13(3)[1]    

defines the minimum frequency with which the organization manually initiates a transfer between active and standby information system components if the mean time to failure exceeds the organization-defined time period;

si-13(3)[2]

defines the time period that the mean time to failure must exceed before the organization manually initiates a transfer between active and standby information system components; and

si-13(3)[3]

manually initiates transfers between active and standby information system components at the organization-defined frequency if the mean time to failure exceeds the organization-defined time period.

potential assessment methods and objects:
