Complete Guide to XIoT Security

The Extended Internet of Things (XIoT) is a comprehensive term covering all connected cyber-physical systems. It is not just the traditional “Internet of Things” (IoT) devices you might think of, like smart speakers and wearables. 

XIoT goes beyond that to include:

• Operational technology (OT): This refers to the hardware and software used to control industrial processes, such as factory equipment and power grids.
• Industrial control systems (ICS): These are specialized computer systems used to monitor and control industrial processes.
• Industrial IoT (IIoT): This subset of XIoT refers specifically to the use of IoT technologies in industrial settings.
• Connected medical devices (IoMT): This includes devices like pacemakers, insulin pumps, and MRI machines.
• Other IoT devices within the enterprise: These could include building management systems, security cameras, HVAC control, elevators, and vending machines.

So, XIoT is essentially the next level of the IoT—a more connected and intelligent version that combines all of these different types of devices and systems. XIoT has the capacity to create many new opportunities for automation, efficiency, and innovation.

Before going into the details, let’s start with understanding IoT.

What Is IoT?

The Internet of Things (IoT) refers to the interconnection of everyday physical objects to the Internet, enabling them to collect and exchange data. 

This interconnected network facilitates a perfect flow of information between devices, contributing to a more efficient and automated environment. Numerous examples illustrate the pervasive impact of IoT across various sectors. 

For instance, in manufacturing, IoT-enabled sensors can monitor equipment performance in real time, predict potential failures, and trigger preventive maintenance. 

In the energy sector, smart grids leverage IoT to manage and control power distribution more intelligently, ensuring reliability and optimizing energy consumption. 

These examples underscore how IoT in OT enhances productivity and contributes to creating more resilient and adaptive systems in critical industries.

What Are XIoT Devices?

XIoT, short for Extended Internet of Things, covers three categories of devices found in diverse settings: enterprise IoT devices, network devices, and operational technology (OT) devices.

Examples of XIoT Devices

The integration of interconnected devices and equipment within organizations holds the potential to herald a “fourth industrial revolution” on the business front. More than 80% of executives spanning diverse industries acknowledge the IoT, citing its critical role in various aspects of their business operations. 

The universality of “smart objects” permeates daily life, ranging from “smart home” intelligent thermostats, smartphones, and laptops to intricate industrial machinery and expansive transportation networks. 

Governments are contemplating the realization of comprehensive “smart cities” driven by large-scale IoT applications. The all-inclusive objective of IoT is to elevate efficiency, refine decision-making processes, and unlock novel opportunities by comfortably merging digital and physical existence.

What Are the Challenges of XIoT?

While the extended Internet of Things offers transformative benefits, its implementation also faces several challenges. Mastering these challenges is crucial for ensuring the successful integration of XIoT technologies across diverse sectors.

Challenges:

Security Concerns

Ensuring the security of interconnected devices is a primary challenge. System vulnerabilities may lead to unauthorized access, data breaches, and potential threats to critical infrastructure.

Interoperability Issues

The diverse range of devices and protocols in XIoT can result in interoperability challenges. Ensuring seamless communication and compatibility between different technologies remains a complex task.

Data Privacy

Collecting and managing vast amounts of data in XIoT raises concerns about privacy. Striking a balance between utilizing data for insights and safeguarding individual privacy is an ongoing challenge.

Scalability Challenges

As the number of connected devices expands, scalability becomes challenging. Ensuring that XIoT systems can handle growing amounts of data and devices without compromising performance is crucial.

Power Consumption

Limited power sources constrain many IoT devices. Optimizing power consumption while maintaining functionality is challenging, particularly in remote or resource-constrained environments.

The Complexity of Implementation

The complexity of implementing XIoT solutions, especially in existing infrastructures, can be a barrier. Integration may require significant investments in both technology and workforce training.

Lack of Standards

The absence of standardized protocols and frameworks in the XIoT landscape complicates development and deployment. Establishing common standards is essential for seamless collaboration and compatibility.

Data Management

Managing the vast volume of data generated by interconnected devices poses a challenge. Efficient storage, processing, and analysis of this data are crucial for deriving meaningful insights.

Why Are XIoT Devices Easy Targets?

Generally, xIoT devices have weaker security compared to laptops, servers, smartphones, and other IT systems. They can’t use anti-malware or endpoint monitoring software. Many use default or weak passwords, and most have risky vulnerabilities. 

A lot of these devices, often called “shadow xIoT,” are unknown to security teams. They might not be monitored for issues or suspicious activity, even when they are known. In many organizations, it’s unclear who is responsible for xIoT security—IT teams, IT security teams, the OT groups deploying the devices, or sometimes no one at all.

Why Is XIoT Device Security Difficult? A Detailed Analysis

As discussed earlier, XIoT devices pose unique security challenges, setting them apart from traditional IT systems. Let’s understand the possible reasons behind this.

Vendors’ Security Priorities

Security isn’t typically a top consideration for XIoT device makers. Their focus tends to be on delivering impressive features for functions like sensing, measuring, and controlling. Security often becomes an afterthought, leading to issues like inadequate protection against tampering and insecure storage of credentials.

Constraints on Single-Purpose Devices

Devices like sensors and monitors, designed for specific purposes, face constraints in terms of space, power, and real-time performance. These limitations often discourage vendors from incorporating robust security features that might demand more power and computing resources.

Vulnerabilities in Multi-purpose Devices

Some XIoT devices, while considered single-purpose, actually run on standard IT technologies like Linux and Android. Unfortunately, vendors often neglect to secure these devices properly, thus leaving them open to malware and ransomware attacks.

Long Replacement Cycles

Unlike traditional IT equipment, which refreshes every few years, XIoT devices often have replacement cycles exceeding 10 years due to cost and logistical challenges. This means older devices might lack the latest security features and software updates.

Massive Scale

Enterprises deal with a large number of XIoT devices per employee, making manual management impractical. Automation becomes essential to monitor and address security concerns at scale effectively.

Inability to Use Traditional IT Security Tools

Most security tools used by IT teams are designed for systems that can host security agents and communicate through standard protocols. However, many XIoT devices lack these capabilities, making traditional security tools ineffective.

No Place for Security Agents

XIoT devices often cannot run local agents used by anti-malware and endpoint detection tools, limiting the applicability of these common security measures.

Standards Complexity

Numerous IoT and OT security standards and frameworks exist, offering recommendations for device vendors and security teams. However, the diversity of these standards can lead to inconsistencies across networks of XIoT devices.

The challenges in securing XIoT devices arise from a combination of vendor priorities, device constraints, vulnerabilities, extended replacement cycles, scale, tool limitations, and the complexity of existing standards. Addressing these challenges requires a comprehensive and adaptive approach to ensure the security of interconnected devices in our evolving technological landscape.
