Securing Industrial IoT: Protecting Against Cyber Threats

In recent times, there has been a massive adoption of the Internet of Things in all kinds of industrial settings. It plays a huge role in connecting devices or objects to the internet. Moreover, it allows them to collect and share information. 

But guess what? This industrial Internet of Things is also one of the prime targets for cyber attacks. IIoT has the potential to increase the vulnerability of all the devices to the cyber threats. 

What is the industrial Internet of Things mainly comprised of? Well, there are sensors, actuators, and manufacturing processes connected to the internet. It helps to increase their efficiency. 

However, despite the advantage of such connectivity, IIoT opens up a gate for cyber threats and makes industrial cybersecurity a central concern.

Understanding Industrial IoT And Its Vulnerabilities

Industrial IoT systems, or IIoT, are vulnerable to all kinds of attacks that can possibly disrupt complete operations. In this section, we will learn about industrial IoT and its vulnerabilities.

What Is Industrial IoT?

Firstly, we will talk about the industrial Internet of Things. 

Industrial IoT involves implementing IoT technologies in industrial applications. These devices are connected within industries such as: 

• Manufacturing, 
• Energy, 
• Transportation, and others.

But what does it do? Well, the industrial Internet of Things mainly helps: 

• To collect data, 
• Monitor conditions and 
• Automate processes. 

Moreover, an IoT ecosystem utilizes smart sensors, actuators, controllers, and communication networks, all interacting to enhance productivity and efficiency.

However, with the increased connectivity and automation that IIoT brings, the importance of industrial cybersecurity cannot be overstated. 

Increased interconnectedness of industrial systems heightens their vulnerability to cyberattacks.

Common Vulnerabilities In IIoT Systems

• Legacy Systems: Firstly, most industrial environments have inherited legacy systems that were not designed with cybersecurity in mind. These outdated systems lack security features that would protect them from modern cyber-attacks.
• Complexity and Scale: Secondly, IoT networks range in size from large to very complex and are difficult to monitor and secure. 

IIoT networks are often highly distributed—sometimes covering several square kilometers—increasing the attack surface through the number of endpoints that provide several entry points through which a cyber-attack may be carried out.

• Lack of Standardization: Thirdly, the lack of security protocols and practices among different devices and vendors introduces inconsistencies and gaps in security measures. 

It is, therefore, quite hard to apply holistic cybersecurity strategies.

• Remote Access: Then comes the matter of remote access. The requirement of remote access to IoT devices for maintenance and monitoring purposes opens other vulnerabilities. 

Thus, unauthorized access to the systems brings about significant disruptions or even potential damage.

• Insider Threats: Lastly, the employees or contractors who have access to the IIoT system might pose a massive threat to organizational integrity, knowingly or unknowingly. Insider threats are pretty hard to detect and mitigate.

Impact Of Cyber Threats On Industrial IoT

Even though it is dependable on the application, a data breach in the IIoT can result in massive risks. In this section, we will learn about the impact of cyber threats on Industrial IoT. 

Operational Disruptions

The IIoT systems are subject to cyber attacks, which can cause severe disruptions in operation. For instance, ransomware attacks lock critical systems, thus generally coming to a halt in the production lines, while some result in expensive downtime. 

Moreover, infections from malware result in data corruption and disrupt communication between devices, leading to inefficiency and delays. 

Safety Risks

The top priority in an industrial environment is safety. Cyber attacks on IIoT systems may result in dangerous situations wherein devices malfunction or operate under unsafe conditions. For example, manipulating sensor data to show incorrect readings. 

These can result in severe accidents and damage to workers, substantial financial harm, and reputation damage.

Data Breaches

IIoT devices generate voluminous data, much of which is sensitive and comprises operations, processes, and intellectual property information. 

The targeted cyber-attack on these devices can result in valuable data being stolen, hence financial losses and competitive disadvantages. 

Additionally, Such breaches may further be responsible for regulatory penalties and reputational damage to companies.

Financial Losses

The financial cost of the cyber attack on IIoT systems can be significant. These include not just immediate costs like 

• Ransom paid,
• Remediation efforts, and 
• Legal fee expenses. 

But, it also includes long-term costs such as productivity loss, reputation damages, and reduced customer trust. 

More so in the case of small and medium enterprises (SMEs), usually short of resources and wherewithal for quick recoveries.

Strategies For Securing Industrial IoT

Industrial IoT networks always differ from other enterprise data networks. Thus, it is necessary to have a proper security strategy that can be specifically used for new sensors and devices. 

Industrial Cybersecurity Robust Measures Implementation

• Risk Assessment and Management: Conducting elaborate risk assessments in search of vulnerabilities and threats is only a starting point for securing IIoT systems. 

Such risk assessments must be reviewed continuously to implement strategies aimed at mitigating these risks.

• Network Segmentation: This isolates the IIoT network into sub-networks, limiting the propagation of cyber-attacks.

This basically involves creating barriers within a network so that in case there is a breach, it will stay contained and will not affect the most critical systems.

• Encryption and Authentication: Stringent symmetric and asymmetric encryption protocols must be implemented along with MFA.

This way, even in the case of interception, the data is not easily readable or changeable.

• Regular Updates and Patch Management: The IoT devices and systems are supposed to be kept updated with the latest security patches and firmware updates. Regular updates address known vulnerabilities and protect against emerging threats.
• Intrusion Detection and Prevention Systems (IDPS): Implementing IDPS can identify and block unauthorized access and malicious activities. 

Therefore, the IDPS is configured to monitor network traffic to follow any indication of the occurrence of suspicious activity and can automatically block several types of threats.

Ensuring Physical Security

• Secure Access Points: This is the physical access of IoT devices and network infrastructure, which should be given to only authorized persons. 

Moreover, physical access control, either by Biometric authentication, Key cards, etc., prevents unauthorized access.

• Tamper-Proof Enclosures: Tamper-proof enclosures for critical IoT devices help in deterring and detecting physical tampering and unauthorized modifications. 

These provide another level of defense from physical attacks.

Improving Employee Awareness And Training

• Cybersecurity Training: Proper training regarding cybersecurity best practices should be given on a regular basis to employees and contractors to enable them to prevent insider threats. 

Additionally, this should include training on solid passwords, recognizing and fending off phishing attempts, and reporting unusual activities.

• Security Policies and Procedures: Clear policies and security procedures will allow all employees to comprehend their role and responsibility in maintaining cybersecurity. 

The organizations must review their policies and update them on a regular basis. This way, they can keep up with all the potential threats. 

Harnessing Advanced Technologies

• Artificial Intelligence and Machine Learning: AI and ML technologies in cybersecurity analyze heaps of data to finally pick out the patterns that indicate cyber threats. 

The technologies will, hence, aid in anomaly detection and threat response in real-time.

• Blockchain Technology: Blockchain will provide secure, decentralized data storage and transmission for devices from IIoT. 

With blockchain technology, an organization will be able to ensure the integrity of its data and thus guard against tampering or other unauthorized access.

• Edge Computing: This can be realized by reducing the quantum of data being sent across the network, hence reducing the possibility of its interception. 

Processing at the edge enables the processing of data closer to its source, therefore improving security and reducing latency.

Collaborate With Industry Partners:

Industry Standards and Frameworks: Industry standards and frameworks, such as the NIST Cybersecurity Framework, help organizations implement best practices in security for the IIoT. 

Such standards advise on the identification, protection, detection, response, and recovery from cyber threats.

Information Sharing: Industry partners can collaborate and share threat and vulnerability information, improving the collective efforts in cybersecurity. 

This may, in turn, support the improvement of the security posture of an organization through the accretion of knowledge and experience from the industry.
