Threat DF.A.HPDS-VDADF.6

URI: DF.A.HPDS-VDADF.6

Description: Service Process cannot decrypt data Data for transmission to FlowsTo: the stored copy of Data on Host is encrypted, but FlowsTo expects an unencrypted version, and Process has no means to decrypt the data before sending it.

Threat Type: Secondary Threat

Matching Pattern:

MP-HPDS-VDADF

Finds a Host storing a Data Copy not encrypted with keys from a vault, that is read and sent in a data flow by a Process on the same Host, plus optionally the Host and Process managers.

DS.X.HDSV.6

Stored copy of Data on Host is encrypted: which means this copy is not available for unencrypted access.

DS.X.HDS-V.6

Stored copy of Data on Host is encrypted: which means this copy is not available for unencrypted access.

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if a flows of updates from FlowsFrom is not available, then Process cannot update this copy of Data which will become out of date.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data Data to Process is interrupted, that would have been displayed to user Human, they may make decisions based on the out of date information.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of data Data but does not depend on it, if that copy is unavailable, the process can continue but will be processing out of date information.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.

LossOfAvailability at Role_DataFlow

CSG-DataAccessKey	Process *Process* has a key for encrypting or decrypting data *Data*.
CSG-DataFlowEncryptionFromProcess	The data *Data* sent by *Process* to *FlowsTo* is encrypted end-to-end (i.e. not relying on transport level encryption).
