Threat Co.U.CoPDS.0.2

URI: Co.U.CoPDS.0.2

Package: IoT

< prev | next >

Description: Loss of reliability due to out of date input at Controller: if the onboard data at a controller is out of date, it means the controller will not be reliable unless it does not require real-time updates to operate safely.

Threat Type: Secondary Threat

Matching Pattern:

Co.U.CoPDS.0.2
MP-CoPDS

Finds a Controller with its stored control input data.

Co.U.CoPDS.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Data: if process Process is not available, then it cannot update a local stored copy of Data on Host, which will become out of date.
Co.U.CoPDS.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Data from FlowsFrom is stored by data service Process on Host: if the flow of data Data from FlowsFrom to Process is out of date, then so will be the copy saved locally on device Host by Process.
Co.U.CoPDS.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if a flows of updates from FlowsFrom is not available, then Process cannot update this copy of Data which will become out of date.
Co.U.CoPDS.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from FlowsFrom is not encrypted, then Process cannot update this copy of Data without a key, so this copy will become out of date.
Co.U.CoPDS.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from FlowsFrom is encrypted, then Process cannot update this copy of Data without a key, so this copy will become out of date.
Co.U.CoPDS.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to save updates unless it has a key or can produce the data in the encrypted domain, so this copy of Data will become out of date.
Co.U.CoPDS.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Output Data computed by Process from stale inputs is stored on Host: if process Process uses out of date inputs, then its output Data computed by Process (not obtained from a user) and saved locally on device Host will also be out of date.
Co.U.CoPDS.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-SafeIoTController

The IoT controller device Controller is regulating a physical system where it is not necessary to get real-time updates to control input data, due to the nature of the IoT application. This control strategy does not represent a contingency plan to constrain Controller at run-time, but should be used to signal that the IoT application is not sensitive to temporary interruption in the flow of control inputs.

CSG-SafeIoTControlMode

The IoT controller device Controller can be set to operate within safety limits such that it poses no danger to the physical system it regulates, even without real-time control inputs. This strategy represents a contingency plan, which can be used to reduce risk from some threats. However, it may trigger other threats, or produce some loss of efficiency or function in the physical system.

CSG-SafeIoTControlMode-Implementation-Runtime

The IoT controller device Controller has been set to operate within safety limits in response to an interruption in real-time control inputs, such that it poses no danger to the physical system it regulates. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. To activate it at runtime, signal user HostManager who is responsible for managing the device. The Safe IoT Controller control shoud be deselected only when the restrictions on Controller have been lifted.
