Package: IoT

Description: Loss of integrity at sensor Sensor: if the onboard data received from a sensor by any client is corrupt, it is modelled as a loss of integrity at the sensor.

Threat Type: Secondary Threat

Matching Pattern:

Se.I.SePDsFF.0
MP-SePDsFF

Finds a Sensor with its onboard process and data, plus all flows of this data from the process (i.e., out of the sensor), at least one of which must be involved in the pattern.

Loss of reliability at DB corrupts outbound flow of data Data to FlowsTo: if there is a loss of reliability at process DB it may send corrupt output Data to FlowsTo. Normally, this is not considered likely when DB is acting only as a data relay, but DB is a DB process which processes incoming queries before requesting or forwarding data, so a loss of reliability may lead to the wrong data being retrieved or updated.
Se.I.SePDsFF.0
DF.I.HDBDSDF.0

Loss of reliability at DB corrupts outbound flow of data Data to FlowsTo: if there is a loss of reliability at process DB it may send corrupt output Data to FlowsTo. Normally, this is not considered likely when DB is serving stored data, but DB is a DB process, so it selects data by processes incoming queries, so a loss of reliability may lead to retrieval or update of the wrong data.
Se.I.SePDsFF.0
DF.I.HDCDF.0

Cached flow of data Data from FlowsFrom to FlowsTo corrupted on Host: if the flow of Data from FlowsFrom to FlowsTo is cached on Host, and the cache is corrupt, the data flow will be affected. This is a secondary threat whereby changes to the cache propagate to the data flow - the cause is whatever caused the cache to lose integrity.
Se.I.SePDsFF.0
DF.I.HPDSDADF.0

Service Process serves a corrupt stored copy of data Data to FlowsTo: if the locally stored copy of Data on Host served by Process is corrupt, so will the flow of Data served to FlowsTo.
Se.I.SePDsFF.0
DF.I.HP-iDODF.0

Loss of reliability at Process corrupts outbound flow of data Data to FlowsTo: if there is a loss of reliability at process Process it may send corrupt output Data to FlowsTo.
Se.I.SePDsFF.0
DF.I.HuirPiDF.0

User Human interacting with Process provides incorrect input Data: user Human provides incorrect input Data to Process, due to having previously received corrupt data from the system.
Se.I.SePDsFF.0
DF.I.DScSePDmFF.0.1

Corrupt control input causes loss of integrity in output Data from Sensor: if the control input to Sensor is faulty or corrupt, then measurement of the environment by Sensor will be affected, leading to faulty or corrupt sensor output Data.
Se.I.SePDsFF.0
DF.I.DScSePDmFF.0.2

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.
