Securing Connected Ecosystems with MCA

The Internet of Things (IoT) has shaped how industries operate, connect, and innovate. At MCA, we recognize IoT's immense potential in smart buildings, industrial automation, and critical infrastructure. However, every opportunity carries its risks. IoT’s rapid proliferation has raised new cybersecurity challenges, making robust security measures an option and imperative. 

With Digi International, one of our top cellular router manufacturing partners in the IoT connectivity space, we explore the latest IoT cybersecurity trends and best practices, underscoring the steps businesses must take to protect their interconnected ecosystems.

Why IoT Security Is More Relevant Than Ever

Data is the engine of innovation across enterprises. IoT continuously delivers revolutionary insights for today's industries, whether enabling real-time automation, improving grid efficiencies, or powering connected healthcare solutions. Yet, every additional IoT device integrated into a network represents a new entry point that cybercriminals could exploit. This underscores the urgent need for resilient IoT cybersecurity strategies to protect sensitive data and guarantee operational reliability. At MCA, we align with Digi International, emphasizing security as the foundation of scalable and sustainable IoT deployment.

Critical IoT Cybersecurity Trends and Threat Landscapes

One company leading this charge is an organization that offers advanced data analytics for in-store refrigeration and HVAC systems across North America. Their use of Ericsson NetCloud Service for IoT and plug-and-play LTE routers and 5G adapters are revolutionizing how grocers manage their infrastructure and data, while providing a secure and isolated network for the IoT systems they depend on.

IoT solutions, such as the ones deployed by the HVAC and refrigeration company, drive transformative results for food retailers, enabling smarter operations, improved energy efficiency, and enhanced security.

Exponential Growth of IoT Devices

IoT Analytics projects an estimated 40 billion connected devices by 2030, surpassing 2015. This incredible growth accelerates innovation but magnifies cybersecurity exposure. Organizations must prepare for a surge in connected endpoints by adopting layered security and proactive monitoring to counteract vulnerabilities.

Skyrocketing IoT Cyberattacks

According to Zscaler, cyberattacks targeting IoT infrastructure increased by 400% year over year. Particularly vulnerable are manufacturing sectors, central to Industry 4.0 innovation, but facing an average of 6,000 IoT device-related cyber incidents per week. MCA’s collaboration with Digi International focuses on providing foundational protections like secure firmware updates and network management solutions to address these alarming trends.

Unencrypted Traffic and Data Risks

According to research from Unit 42 and Palo Alto Networks, a staggering 98% of IoT device traffic remains unencrypted. This lack of encryption leaves valuable data vulnerable to interception and theft. Encrypting traffic is no longer optional—it’s a critical priority. To scale IoT securely, secure transfer protocols and widespread encryption adoption must be embraced.

Fragmentation of IoT Security Standards

The lack of standardization across IoT security protocols leaves significant gaps, especially when outdated systems persist within connected device ecosystems. For example, the HIPAA Journal found that only 17% of IoT devices currently receive proper support from the operating system. MCA takes deliberate steps to ensure that our IoT deployments meet rigorous security standards, alongside partners like Digi International, whose solutions prioritize current, secure firmware.

IoT Security Investments Rapidly Expanding

According to Markets and Markets, global spending on IoT security solutions will grow from $24.2 billion in 2024 to $56.2 billion by 2029. The growth reflects an acknowledgment across industries that robust security is the linchpin of IoT innovation. At MCA, we remain at the forefront, guiding organizations with tailored solutions that merge advanced functionality with airtight security.

IoT Cybersecurity Best Practices

MCA and Digi International advocate for a multifaceted approach to IoT cybersecurity. Building resilient defenses requires a mix of both foundational and advanced best practices, including:

  • Encryption First: Employing robust data encryption ensures information exchanged via IoT devices remains secure from unauthorized access.
  • Secure Boot Processes: Prevent malicious code initialization through system integrity verification at startup.
  • Physical Device Protection: Restrict access to hardware with tamper-proof measures and controlled environments.
  • Real-Time Monitoring: Regularly assess network health with tools like Digi Remote Manager®, ensuring quick vulnerability response.
  • Network Segmentation: Isolate IoT devices from critical systems to mitigate widespread damage in the event of a breach.
  • Authentication and Access Control: Enforce unique device passwords and allow only authenticated devices within the network.
  • Firmware Updates: Proactively patch vulnerabilities with automated updates.

By adopting these comprehensive strategies, enterprises can build multi-layered defenses that minimize attack surfaces and ensure operational reliability.
