iot data management is done by the cisco kinetic iot platform to extract, move and compute the data. devicehive is another rich iot open-source platform that is distributed under the apache 2.0 license and can be used and changed free of charge. the sap internet of things cloud platform has everything you need to build and handle an iot application. without the microsoft azure solution, a cloud service giant with aws and google cloud platform, the comparison of our iot platform will be not complete.
in smart cities and the automobile industry, hpe universal of things platform was used properly. the cost-efficient platform allows you to connect all your appliances to a cloud solution. the platform provides services from over 60 partners and free access to a community of 200,000 designers. the platform seeks to provide industrial iot devices and clouds with security. iot promotes and links all elements in the scheme.
this chapter is lengthy relative to the other chapters in part because there are many iot framework standards available and each takes a different perspective. this chapter is lengthy relative to the other chapters in part because there are many iot framework standards available and each takes a different perspective. the use of iot technology to implement a completely new iot system spawns unique applications for operational automation; building such a system with wholly new technology and protocols is sometimes referred to as greenfield iot technology. the technology within a particular ecosystem is specialized for that ecosystem, its business models, as well as the producers and consumers in that market. the framework data model describes a view of the network where nodes appear as flat or nested data structures, and updates to data values may result in actuation of various controllable elements. when viewed from a manufacturing perspective, the device is a physical component consisting of hardware, firmware, and system software. when viewed from an application perspective, the iot framework data abstractions can make it difficult for application code to tell when a physical device boundary is crossed. securing software defined devices requires a trusted execution environment that creates trustworthy hardware isolation and exposes security roots of trust to the soft device. the remote device expects to receive an attestation report that is signed by a trustworthy signing key protected by a root-of-trust for reporting. the tpm is an example of a discrete processor that combines roots-of-trust for storage and reporting. the uds and deviceid derivation functionality form a root of trust that is simpler than a traditional trusted platform module (tpm), secure co-processor or tee. iot platforms and devices follow a lifecycle (figure 2-5) that may begin during manufacturing and ends when the device is decommissioned or waterfalled to another owner for redeployment starting another lifecycle. then the entity responsible for adding iot devices to their network is sometimes called the “owner” which implies a change of ownership and establishment of a “local” identity that differs from a manufacturer or supply chain supplied identity. decommissioning is the process of undoing onboarding, commissioning, and provisioning that were applied previously. the framework provides a semantically rich description of iot nodes, objects, and interactions that allow iot network designers to focus only on node interaction semantics rather than on the details of connectivity. the top layer of the framework is iot use case specific in that it exposes a data model abstraction that reinforces an iot usage context. to a certain extent, iot frameworks can be compared with information-centric networking (icn).footnote 12 icn rethinks the network where named information is the centerpiece of network architecture. the framework layer may not be aware of the impact to authorization which can result in the framework misrepresenting actual security posture to iot applications. iot frameworks may expose manageability elements through the framework object abstraction layer as a way for other framework objects and resources to better manage and respond to change resulting from management activity. iot device roots of trust should be used to protect device identities and ensure the appropriate firmware and software is loaded and executed. by allowing applications to focus only on the semantics of iot node behavior and node interactions, interoperability improves. complexity in any form, however, is a security consideration because vulnerabilities and security weaknesses can hide within the corners of complexity. the gateway application contains control and management logic to present nodes to a peer iot network that shadow actual nodes existing deeper inside the local iot network. ideally, the security endpoint context is the central point of enforcement where the flow of data between the data object layer and the connectivity layer can be inspected and controlled. the device driver and api are most often proprietary and specific to the vendor and model of the sensor or actuator. root-of-trust hardware is essential to the creation and protection of device identities that may be used to attest device security properties to a peer node and to security boot the device. the security context-a is a fulcrum point in the framework that uniformly applies an iot network security policy involving the peer nodes and node-a. at the time of this writing, an object security for constrained restful environments (oscore) draft specificationfootnote 22 defines a rest message binding to coap and http. the core framework layer defines several built-in resources used to implement several of the services and capabilities offered by the core layer. introspection can be used by a client to obtain a machine-readable description of all the resources, properties, and interface definition syntax. the ocf uri contains a device identifier in the form of a uuid followed by a reference to its resources. if a role is asserted, then acl entries that specify a role name could be used to match the requestor. the device is guaranteed to be in one of these five states throughout its deployment. a security challenge facing ocf frameworks is the binding between the lower framework layer to the platform and its security capabilities isn’t defined by the specification.
an application must know which transport protocol to use and an appropriate d-bus name when attempting to connect to a peer leaf node known as the “bus address.” d-bus supports several status and discovery commands that may be helpful in determining the health of d-bus daemon processes: org.freedesktop.dbus.introspectable is used to obtain an xml description of the interfaces, methods, and signals the device implements. effective data-level protection at the application layer requires data formatting and encapsulation technology that is part of its data model. the upnp protocol stack (figure 2-11) may be regarded as iot frameworks, though loosely as upnp is tightly bound to ip and the network services built around ip such as dhcp, dns, ip multicast, and so on. control: control point code is expected to identify which commands and data objects are supported by the service to construct a program sequence that uses them to achieve application objectives. the open connectivity foundation and the upnp forum merged in 2016. they defined a bridging specification that allows ocf and upnp devices to interact; however the ocf bridging specifications do not define security interoperability. the lwm2m client is the managed node and corresponds to a sensor/actuator device. introspection is not supported except through the use of a separately defined introspection service – something that wasn’t defined at the time of this writing. once the client device is configured, it may interact with other iot nodes as an iot service such as a sensor or actuator. a onem2m reference point uses the nomenclature “mc-” meaning m2m communication to the entity “-” – where the dash is a placeholder for the first letter of the entity name. management gateways, proxies, and bridging functions fall within the scope of device management functions. the group management csf must validate group membership and whether the group member is capable of performing functions meaningful to the group. that is to say, each of these security requirements was considered and addressed to a certain extent. the architectural principles defined by the iic reference architecture serves as a reference point for evaluating the merits and demerits of iis framework solutions. the user benefits of autonomous operation (without users) may be compared to perceived and actual benefits of user involvement in setting and evaluating security relevant decisions. the business domain functions as a layer on top of operations, information, and application domains that interact with the control domain. the output of one shop floor device may be consumed as input to another shop floor device. as long as there is a framework instance that runs on the os and hardware of interest, iiot device interoperability exists. it also can be used to authenticate applications that connect with the opc-ua framework. the primary design goal is summarized as the efficient and robust delivery of the right information to the right place at the right time. data readers: correspond to the subscribers of a publish-subscribe interaction pattern and must create a subscriber instance object in order to register to receive publications. deadline: controls the interval in which a topic is expected to be updated. reliability: allows reliability to be defined in terms of levels, best_effort being the lowest and reliable being the highest. implied by the dds layering architecture is a device system layer that implements the iot device capabilities including native security and manageability capabilities. it is even possible to construct a domain broker that gives the illusion of the same topic appearing in separate domains. the dds framework takes a modular approach to security so that platform-specific capabilities can be exposed to and utilized by dds entities. for example, dds doesn’t appear to support attestation protocols that would query a peer principal’s security subsystem to provide proof of device provenance and integrity of the system firmware, software, plugins, and dds framework layers. ironically, the “success” of iot seems to have created a more complex environment for iot interoperability as both standard and proprietary “connectivity” frameworks and toolkits proliferate. a traditional framework may not be regarded as a type iii gateway depending on the set of protocols and message types the framework supports. a lwm2m object identifier is a uri that is constrained to two layers of nesting, and object names are numeric. in general, the gateway is expected to be one of the most trusted nodes in the network. this implies the data will be unprotected through some portion of framework layering before handing off to the gateway translation application and again in the reverse flow. framework a resources at the interaction and connectivity layers are strictly isolated from framework b. however, because the object translation logic is shared across network a and network b, the data object layer, compromise of this layer implies access to both a and b networks. the meaning of an idealized architecture is it attempts to describe iot framework architecture where security is central to the design and integrated from the start. new and existing proprietary approaches also seem to have gained ground as the size of iot grows. in summary, frameworks appear to offer significant value for enabling interoperable iot applications by hiding much of the complexity of multiple connectivity technologies, messaging solutions that incorporate multiple hundreds or thousands of nodes, and data schemas that present consistent, declarative, and vendor-neutral expressions of iot objects.
