Threat DF.I.DScSePDmFF.0.2

URI: DF.I.DScSePDmFF.0.2

Package: IoT

< prev | next >

Description: Out of date control input causes loss of integrity in output Data from Sensor: if the control input to Sensor is out of date, and Sensor depends on real-time updating of this input, then measurement of the environment by Sensor will be affected, leading to faulty or corrupt sensor output Data.

Threat Type: Secondary Threat

Matching Pattern:

DF.I.DScSePDmFF.0.2
MP-DScSePDmFF

Finds a Sensor with its onboard process and output data, and its stored copy of control input data, plus all flows of this data from the process (i.e., out of the sensor), all of which must be involved in the pattern.

DF.I.DScSePDmFF.0.2
DS.T.HPDAuDS.0

Unavailable process Process cannot update stored copy of Data: if process Process is not available, then it cannot update a local stored copy of Data on Host, which will become out of date.
DF.I.DScSePDmFF.0.2
DS.T.HPDFDADS.0

Stale data Data from FlowsFrom is stored by data service Process on Host: if the flow of data Data from FlowsFrom to Process is out of date, then so will be the copy saved locally on device Host by Process.
DF.I.DScSePDmFF.0.2
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if a flows of updates from FlowsFrom is not available, then Process cannot update this copy of Data which will become out of date.
DF.I.DScSePDmFF.0.2
DS.T.HPDFDAuDS-V.6

Encrypted data Data stored on Host cannot be updated by Process with unencrypted input from FlowsFrom: process Process manages an encrypted stored copy of data Data on Host, so if the flows of updates from FlowsFrom is not encrypted, then Process cannot update this copy of Data without a key, so this copy will become out of date.
DF.I.DScSePDmFF.0.2
DS.T.HPDF-VDAuDS.6

Unencrypted data Data stored on Host cannot be updated by Process with encrypted input from FlowsFrom: process Process manages an unencrypted stored copy of data Data on Host, so if the flows of updates from FlowsFrom is encrypted, then Process cannot update this copy of Data without a key, so this copy will become out of date.
DF.I.DScSePDmFF.0.2
DS.T.HPDOuDS-V.6

Process Process cannot update encrypted data Data stored on Host: if the local copy of Data on Host is encrypted, then process Process that creates the data will be unable to save updates unless it has a key or can produce the data in the encrypted domain, so this copy of Data will become out of date.
DF.I.DScSePDmFF.0.2
DS.T.HP-iDOdDS.0

Output Data computed by Process from stale inputs is stored on Host: if process Process uses out of date inputs, then its output Data computed by Process (not obtained from a user) and saved locally on device Host will also be out of date.
DF.I.DScSePDmFF.0.2
DS.T.HuirPiDS.0

User Human interacting with Process provides stale input Data: user Human provides input Data which is stored by Process on Host, so if Human is working on outdated information, the stored copy will also be out of date.

CSG-NonRealtimeSensor

The IoT device Sensor implements a process for measurement of a physical system where it is not necessary to get real-time updates to control input data, due to the nature of the application. This control strategy does not represent a contingency plan but indicates that the application is not sensitive to interruptions in control inputs.
