Description: Loss of availability from suspending the flow of corrupt data Data from FlowsFrom to Process: if a contingency plan is used in which the flow of Data between FlowsFrom to Process is disabled if the data is corrupt, then the flow of data Data from FlowsFrom to Process will become unavailable.

Threat Type: Primary Threat

Matching Pattern:

MP-PDF

Finds a Data Flow (excluding Spam), plus source and destination processes, plus optionally the users responsible for the two processes. The destination process is matched twice so it can be referred to in either role.

Triggers Secondary Threats (5)

DS.T.HPDFDAuDS.0

Data Data stored on Host cannot be updated by Process with input from FlowsFrom: process Process manages a stored copy of data Data on Host, so if a flows of updates from FlowsFrom is not available, then Process cannot update this copy of Data which will become out of date.

Hu.T.HuirPvDF.0.2

User Human affected by unavailable data Data from FlowsFrom received by Process: if the flow of data Data to Process is interrupted, that would have been displayed to user Human, they may make decisions based on the out of date information.

P.A.PuDFDI.0

Lack of incoming Data affects availability of Process: process Process depends on an incoming flow of Data from FlowsFrom, so if that is unavailable the availablity of the process will be affected.

P.T.P-uDFDI.0

Loss of availability in flow of Data to Process caused a delay in processing: since process Process uses the incoming copy of data Data but does not depend on it, if that copy is unavailable, the process can continue but will be processing out of date information.

Se.A.SePDmFF.0

Loss of availability at sensor Sensor: if the onboard data from a sensor is not available to any client, it is modelled as a loss of availability at the sensor.
