Description: The asset cannot (or will not) carry out its function within the system, failing to interact with other assets as expected.

This misbehaviour affects the trustworthiness attribute Availability

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.

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.

DataCentre

A building or buildings containing physical hosts and networks that can itself be connected to other networks, and used to support virtual hosts and management via a cloud platform. Internal connections and resources will be inferred where necessary, if not added manually.

Host

A device that can store, process, transmit or receive data.

NetworkAsset

Base class for all network assets excluding host devices, including abstract and real subnets, network interfaces, routes through gateway hosts, and extended network paths.

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.

Human

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