FUNDAMENTALS OF SECURED REMOTE ACCESS FOR INDUSTRIAL/AUTOMOTIVE/IoT DEVICES.

Securing Operational Technology (OT) devices on the cloud is critical as industries shift towards more connected, cloud-integrated environments. OT (Operational Technology) refers to hardware and software that detects or causes changes through direct monitoring and control of physical devices, processes, and events within industrial settings.

Here is a compilation of the technologies that a remote access platform need to adhere to be best in class to protect Operations Technologies.

UNDERSTANDING FUNDAMETALS OF OPERATIONAL TECHNOLOGY (OT) DEVICE.

At the core of the digital ecosystem lies the Industrial Internet of Things (IIoT), a network of physical objects imbued with the ability to collect and exchange data through the Internet. This expansive category of devices includes various products for industrial control and data collection to make them efficient.

For example, programmable Logic Controllers (PLCs) play a crucial role in the digital ecosystem by bridging the gap between physical systems and digital control processes. They are foundational components in automation (OT) environments along with Human machine interfaces (HMI) devices. These devices are used for energy management, HVAC control system Security and Access Control, Elevator and Escalator Control Systems, Smart Lighting, Smart sensors, climate control, Security systems and many more custom embedded applications. They make machines smart.

WHY SECURE REMOTE ACCESS OT DEVICES?

In today’s industrial environment, where security and efficiency are paramount in data collection and control to build high performance digital systems, the Industrial Internet of Things (IIoT) emerges as a pivotal innovation, revolutionizing how we interact with the machines. With the ability to remotely control various facets of machines and process, IIoT devices have become integral components of modern industry, seamlessly integrating into daily routines, and providing unparalleled access to industrial electronic equipment to perform with best efficiency and ease of use is of prime importance.

The essence of secure remote connection function is to add transformative power to seamless connectivity. This intrinsic feature enables these devices to be operated and managed remotely, bridging distances with a few clicks on smartphones, tablets, or computers. This connectivity unlocks the full potential OT devices using secured remote connection, allowing for real-time management and control from virtually anywhere, thus ensuring that users can harness the full spectrum of benefits offered by these smart devices.

KEY ATTRIBUTES OF SECURED REMOTE ACCESS

Secured remote access to Operational Technology (OT) devices is crucial for protecting critical infrastructure in industrial environments. Here are the key attributes of a secured remote access solution for OT devices. By combining these attributes, secure remote access solutions for OT devices can help prevent cyber threats unauthorized access, and operational disruptions while maintaining the critical uptime required for industrial systems.

Zero trust Security principals.

The management and control of IIoT devices go beyond simple digital interactions, involving a complex coordination of processes that ensure the seamless, secure, and intelligent operation of smart devices within a network.

Zero Trust is a security framework based on the principle that no entity, whether inside or outside the organization's network, should be trusted by default. Instead, every access request must be continuously verified before granting access to resources. Achieving proactive secure remote access begins with a holistic approach of adopting a modern solution grounded in zero trust principles. This mechanism allows granular, just- in-time access to individual assets. This robust access controls systems is vital to prevent disruptions, data breaches, and unauthorized access (insider threats), all of which can have serious implications for safety and uptime of machines.

Provisioning and Authentication.

The first step when an IIoT device connects to a network is provisioning. This process meticulously prepares and configures the device to ensure compatibility with the existing technology. This crucial stage establishes the foundation for the device's roles and operations within the network. Alongside provisioning, authentication acts as the gatekeeper, rigorously verifying the identity of each device or user requesting access to the network. This dual process facilitates secure entry into the network and fortifies the network’s defenses against unauthorized access, ensuring that only legitimate, authenticated participants can engage with the ecosystem.

Configuration and control.

The digital landscape is ever-changing, with devices and networks continually adapting to new technologies and demands. Configuration serves as the tool that enables IIoT devices to go beyond their initial settings, allowing for modifications that accommodate this evolving environment. Remote control capabilities add another layer of sophistication, empowering users to adjust device operations from a distance, refine automation, and create more intelligent, efficient interactions within the IIoT ecosystem.

Securing SW updates

In the fast-paced tech world, the software driving IIoT devices cannot remain static. Regular updates and upgrades are crucial, ensuring that each device is protected with the latest security patches and improved functionality. This commitment to continuous improvement not only guards against new threats but also ensures devices adapt to users' changing needs. By prioritizing software maintenance, the longevity, reliability, and performance of IIoT devices are greatly enhanced, allowing them to deliver optimal value throughout their lifespan.

Support diverse modality.

In the complex landscape of IIoT ecosystems, the methods for interacting with and managing devices are as diverse as the devices themselves, each providing distinct benefits and conveniences suited to various user requirements and situations. These modalities need their own secured mechanism that must be invoked with its mode and state.

User Interface.

Secure the user access by integrating secured method to invoke access by adding 2 factor authentication or secured remote password with limited access windows.

Monitoring and Diagnostics.

Constant monitoring and diagnostic capabilities are essential for effective IIoT device management. This ongoing oversight enables users to track the health and performance of their devices, providing valuable insights into operational data like environmental conditions and mechanical efficiency Constant More than just observation, this functionality allows users to customize the system's reactions to specific situations, setting up alerts for critical events such as security breaches or hardware failures. Proactive monitoring helps identify and resolve potential issues quickly, preserving the integrity and security of the entire network.

CONCLUSIONS:

Secured Remote Connection platforms should empower customer to achieve best secure remote access ecosystem that is both powerful and secure. Secured remote access should strengthen OT security offering by cyber-hardening to virtually any cyber-physical system.

Secured Remote Connection platforms must provide robust security controls including point-in-time access and role-based access policy, Least privileged access, Audit trail recording regardless of the native device capabilities. Additionally, it should offers a unified interface for managing, monitoring, and auditing all remote activities. This single pane should improves incident response capabilities.
