Package: Application

< prev | next >

Description: Represents a state in which a data asset is somewhat out of date, or a process or human has outdated or (temporarily) unavailable inputs.

This misbehaviour affects the trustworthiness attribute Timeliness

Data

Represents a class of data items that can be stored on Hosts, or processed and exchanged by Processes. Note that this asset represents the presence of data in the system. Physical copies of the data are represented by inferred assets linked with Processes that serve or use them, hosts where they are stored.

Human

An individual user role within the socio-technical system that uses and/or manages assets.

Process

Represents a process (usually implemented by software running on a Host) that can read, update or create data, or exchange data with other processes.

DataAsset

A base class for all assets representing Data. Used partly to provide a classifier for the palette.

DataField

Represents a specific element within a structured data asset. Used to model the presence of parts in data that may be more sensitive or have extra protection compared to the remaining contents of a data asset.

Sensor

A Thing that can sense its physical environment and produce data describing aspects of that environment including the device user. A sensor has no console allowing login, but it may have an interface allowing some interaction with a human user.

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Data from FlowsFrom is stored by data service Process on Host: if the flow of data Data from FlowsFrom to Process is out of date, then so will be the copy saved locally on device Host by Process.

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if a flows of updates from FlowsFrom is not available, then Process cannot update this copy of Data which will become out of date.

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from FlowsFrom is not encrypted, then Process cannot update this copy of Data without a key, so this copy will become out of date.
LossOfTimeliness
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.
LossOfTimeliness
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.
