Deploying IoT solutions poses significant security challenges, exposing many devices, data, and systems to various cyber threats and attacks. In this article, we will explore IoT projects’ risks with a lens on agriculture, mining and energy industries and expose the best practices and tradeoffs necessary to secure IoT solutions.

IoT security risks in agriculture, mining, and energy

IoT solutions in agriculture, mining, and energy can bring many benefits, such as improving crop yield, optimizing resource utilization, enhancing worker safety, and reducing environmental impact. However, they can also introduce many risks, such as:

• Data breaches: IoT devices collect and transmit large amounts of sensitive data, such as soil moisture, water level, power quality, location, temperature, and gas detection. These data can be intercepted, modified, or stolen by malicious actors, who can use them for various purposes, such as espionage, sabotage, blackmail, or fraud. For example, hackers can access the data from soil moisture sensors in a farm and use them to manipulate the irrigation system, causing overwatering or drought. Hackers can also access the data from water level sensors in a river and use them to trigger false alarms, causing panic or evacuation.
• Device hijacking: IoT devices can be compromised, controlled, or manipulated by malicious actors, who can use them for various purposes, such as launching attacks, disrupting operations, or causing damage. For example, hackers can take over the control of drones or vehicles in a mine and use them to crash into other equipment, workers, or infrastructure. Hackers can also take over the control of smart devices and sensors in a grid and use them to cause power outages, overloads, or fires.
• System disruption: IoT devices can be affected, disabled, or destroyed by malicious actors, who can use them to disrupt the normal functioning of the system or to prevent the system from recovering. For example, hackers can infect the devices with malware, ransomware, or botnets and use them to launch distributed denial-of-service (DDoS) attacks, encrypt or delete data, or spread the infection to other devices. Hackers can also physically damage or destroy the devices and use them to create gaps or bottlenecks in the system or to prevent the system from repairing or replacing the devices.

These risks can have severe consequences for the agriculture, mining, and energy industries, such as:

• Economic losses: IoT security breaches can cause direct or indirect economic losses, such as reduced output, increased costs, wasted resources, or lost revenues. For example, IoT security breaches can affect the quality or quantity of the crops, minerals, or energy produced or the efficiency or reliability of the production process. IoT security breaches can also affect the reputation or trust of the customers, partners, or regulators or compliance with the standards or regulations.
• Environmental damages: IoT security breaches can cause environmental damages, such as pollution, contamination, or degradation. For example, IoT security breaches can affect the management or monitoring of environmental factors, such as water, air, soil, or climate, or the mitigation or adaptation of ecological impacts, such as emissions, waste, or hazards.
• Human harms: IoT security breaches can cause human harm, such as injuries, illnesses, or deaths. For example, IoT security breaches can affect the health or safety of workers, customers, or communities, or the protection or privacy of personal data or information.

IoT security best practices and tradeoffs in agriculture, mining, and energy

Securing IoT solutions in agriculture, mining, and energy is not a trivial task, as it involves various factors, such as the diversity and complexity of the devices, data, and systems, the variability and unpredictability of the environments, the scalability and availability of the solutions, and the tradeoffs and constraints of the resources and requirements. However, some general best practices can help to improve the security of IoT solutions, such as:

• Implementing a proper access control and identity management system. This means ensuring that only authorized users and devices can access the IoT network and data and have the appropriate permissions and roles. For example, in smart agriculture, farmers must protect their yield data, farming methods, and other proprietary information from competitors and third parties. In mining and energy, workers need to access the IoT devices and sensors that control the machinery and equipment, but not the data collected and analyzed by the cloud platform.
• Securing the connection and communication of the IoT devices. This means ensuring that the IoT devices can establish a secure and reliable connection to the IoT network and cloud platform and that the data they transmit and receive is encrypted and protected from eavesdropping, tampering, or interception. For example, in smart agriculture, devices need to connect securely to the cloud platform that provides data analysis and decision support and encrypt the data that contains sensitive information such as crop yield, soil quality, and weather conditions. In mining and energy, devices must connect securely to the network that controls the machinery and equipment and encrypt the data containing critical information such as operational status, environmental parameters, and safety alerts.
• Continuously monitoring the security posture of the IoT systems. This means collecting and analyzing data on the performance, behaviour, and status of the IoT devices and networks and detecting and responding to anomalies, threats, or incidents. For example, in smart agriculture, sensors and cameras can monitor crops and livestock and alert the farmers of any diseases, pests, or environmental changes. In mining and energy, sensors and actuators can be used to monitor the conditions and operations of the mines and power plants and alert the operators of any faults, hazards, or emergencies.
• Implementing the right device update strategy. This means ensuring that the IoT devices run the latest firmware and software versions and receive regular patches and updates to fix any vulnerabilities or bugs. For example, in smart agriculture, devices must be updated to support new features and functionalities, such as precision irrigation, fertilization, and harvesting. In mining and energy, devices must be updated to comply with regulatory and safety standards, such as emission control, noise reduction, and waste management.

Securing an IoT solution is not a one-size-fits-all approach, as different industries and applications may have different security requirements and constraints. Therefore, it is essential to consider the tradeoffs and costs involved in implementing security measures for an IoT solution. Some of the factors that may affect the security tradeoffs are:

• The performance and functionality of the IoT devices. Security mechanisms such as encryption, authentication, and updates may consume additional resources and power from IoT devices, which may affect their performance and functionality. For example, encryption may increase the latency and bandwidth of the data transmission, authentication may require user interaction or additional hardware, and update may require device downtime or user consent.
• The scalability and complexity of the IoT network. Security mechanisms such as device management, monitoring, and patching may become more challenging and costly as the number and diversity of IoT devices increase. For example, device management may require a centralized or distributed architecture, monitoring may require a real-time or periodic approach, and patching may require a manual or automatic process.
• The risk and impact of IoT security breaches. Security mechanisms such as risk assessment, security analysis, and incident response may vary depending on IoT security breaches’ potential threats and consequences. For example, risk assessment may require a qualitative or quantitative method, security analysis may require a static or dynamic technique, and incident response may require a reactive or proactive strategy.

These are some tradeoffs and costs involved in securing an IoT solution. However, these tradeoffs and costs should not be seen as barriers or excuses to neglect IoT security but rather as challenges and opportunities to find the optimal and balanced security solution for each industry and application.

Conclusion

IoT solutions in agriculture, mining, and energy can offer many opportunities and benefits but pose many risks and challenges. 

Securing IoT solutions is not an option but a necessity, as it can protect the devices, data, and systems from various cyber threats and attacks and the industries, environments, and humans from multiple consequences and damages.
