Founded in 1985, Digi International is a pioneer in wireless communication and a leading provider of Internet of Things (IoT) solutions. Their recently released webinar, Three Key Focus Areas for IoT Security, aimed at helping organizations understand the importance of securing their IoT developments and provided expert insight into the three areas that organizations need to focus on to ensure the security of their IoT infrastructure.

The Need for Fortified Security in Connected Systems

IoT devices and connected systems are inherently susceptible to cyber threats and security breaches. According to IoT World Today, from January to June of 2021, there were approximately 1.51 billion breaches of IoT devices as opposed to 639 million in 2020. Some reasons why connected systems are particularly susceptible to cyberattacks include:

  • The growing number of IoT devices
  • Lack of standardization
  • Potential for catastrophic consequences
  • Personal data privacy
  • Liability and reputation risks

Digi International’s webinar reminds developers that securing IoT devices extends beyond encryption and strong passwords. The purpose of IoT security is to prevent operational downtime, ensure that an organization’s customers feel safe and secure, protect personally identifiable (PI) data, and comply with government/industry standards. Additionally, securing IoT systems is a team effort involving manufacturers, customers, corporate users, the government, cloud services, and resellers. Every person/entity interacting with a connect system or device is responsible for security.

Common IoT Device Security Threats

Digi International classifies the following models as common IoT device security threats (Figure 1):

  • Attacks on the boot process
  • Physical attacks
  • Lifecycle attacks
  • Attacks on secure assets
  • Firmware attacks
  • Application attacks

The Challenges of Securing Connected, Artificially Intelligent, and Machine Learning Devices

Digi International suggests that the three places where developers should be focusing their IoT security efforts are connected, artificially intelligent (AI), and machine learning (ML) devices. However, there are some innate security challenges in the development and deployment of these types of devices.

IoT Development Security Challenges

  • Long product development and approval processes
  • Changing regulations (state, federal, and international)
  • Evolving standards in security and encryption
  • Security vulnerabilities in software

IoT Deployment Security Challenges

  • Products deployed in insecure locations
  • Inability to be deployed with other security assets
  • Rapidly accelerating hacking and ransomware challenges
  • Wireless connectivity security
  • Device security and software upgrades
  • Long-term support and decommissioning
