As of October 2023, Internet of Things (IoT) technology has become a standard tool for automating business processes, with 57% of organizations in North America and Europe using IoT devices, according to a Statista study.
However, alongside these benefits, IoT introduces significant cybersecurity challenges. This article by Umal Nanumura, recognized expert in network security engineering, is devoted to various trends of IoT-based solutions implementation.
Unlike traditional IT systems like ERP or CRM, IoT’s varied components—ranging from sensors and cloud systems to RFID and NFC—are more susceptible to attacks due to the lack of standardized security protocols.
Since the early 2000s companies have eagerly adopted IoT for its potential to streamline operations, reduce costs, and optimize processes.
However, as more IoT devices integrate into business systems, many organizations overlook the complexity and diversity of IoT ecosystems, making them prime targets for cybercriminals.
These systems exchange vast amounts of data, often without comprehensive security measures, allowing sensitive information to circulate more freely across networks.
A notable case occurred in 2016 with the Mirai Botnet attack. This malware compromised 600,000 IoT devices, leading to significant data breaches and billions in damages.
Despite the risks, businesses continue to embrace IoT for its undeniable advantages. For example, Royal Dutch Shell saved $1 million after investing just $87,000 in IoT-based oil production monitoring.
Similarly, Harley Davidson reduced its production cycle from 21 days to 6 hours by automating its manufacturing processes with IoT sensors. Even Rolls-Royce utilized IoT in aircraft engines to monitor performance in real time, allowing for quick responses to optimize fuel consumption and improve overall efficiency.
While these success stories demonstrate IoT’s potential, businesses must not ignore the cybersecurity threats that come with this technology.
Many IoT devices still operate with default passwords and lack adequate encryption, making them vulnerable to even basic cyberattacks. Simple preventive measures, such as updating passwords and using encryption protocols, could prevent many common IoT-related breaches.
Cybercriminals are increasingly using unconventional entry points to exploit IoT systems. For instance, in a notorious case at the Silverton hotel in Las Vegas, hackers gained access to a VIP client database by targeting an IoT-connected aquarium thermostat.
Rather than attacking the databases directly, the cybercriminals exploited a weak point in the IoT system, demonstrating how even minor vulnerabilities in these devices can lead to significant data breaches.
To mitigate these risks, businesses are increasingly adopting the Governance, Risk, and Compliance (GRC) methodology.
GRC provides a structured framework for managing vulnerabilities in IoT ecosystems, integrating risk management and compliance processes with cybersecurity tools.
Traditional cybersecurity approaches are often insufficient for IoT environments, but GRC helps create a comprehensive strategy that involves both technical defenses and management oversight.
One promising approach, according to Umal nNanumura, is to combine blockchain technology with GRC for enhanced security. Blockchain’s tamper-proof architecture ensures data integrity, while smart contracts can regulate data sharing and access control in IoT systems.
This layered security approach can be especially beneficial in sectors like healthcare, where privacy and data security are paramount. For example, using blockchain to secure medical data has proven effective in protecting sensitive information from cyberattacks.
Implementing GRC, however, is not without challenges. Many businesses find it difficult and expensive to customize GRC tools to their specific needs.
Errors in configuring these systems can leave IoT ecosystems vulnerable to attacks, and top management may not realize the severity of the issue until critical data has been compromised.
Despite these hurdles, when applied correctly, GRC offers a reliable defense against cyber threats in IoT environments, reducing vulnerabilities and enhancing operational security.
In addition to GRC, businesses can benefit from using automated security tools such as penetration testing and AI-driven real-time threat detection.
These tools can identify and neutralize threats much faster than traditional security systems, providing an extra layer of protection for IoT infrastructures.
As IoT continues to reshape industries, from logistics and supply chains to healthcare and smart offices, the need for robust cybersecurity becomes increasingly urgent.
While IoT’s benefits are clear, organizations must prioritize cybersecurity to protect themselves from financial and operational risks.
Experts in the field recommend adopting comprehensive security frameworks and leveraging advanced technologies to secure IoT ecosystems and ensure long-term success.
