IoT/Device Trust

The Internet of Things is revolutionizing the ways we interact with technology. Ensuring the security and trustworthiness of our devices more critical than ever—and that’s where device trust comes into play.

What is the Internet of Things (IoT)?

The Internet of Things (IoT) refers to a network of interconnected devices that communicate and share data with each other over the internet. These devices range from everyday household items like smart thermostats and refrigerators to industrial machines and healthcare monitors. By enabling seamless interaction and data exchange, IoT enhances efficiency, convenience, and decision-making across various sectors.

Why is IoT device trust important?

As IoT devices become more integrated into our daily lives and critical infrastructures, understanding the threats they face is essential for maintaining a secure and reliable IoT ecosystem. Here are some of the primary cyber threats that device trust addresses:

  1. Unauthorized access and control 
    Weak or default passwords, lack of robust authentication mechanisms, and outdated firmware can make devices vulnerable to unauthorized access.
  2. Malware and ransomware attacks 
    Malware can be introduced through various means, including malicious software updates, infected peripherals, or compromised network connections. Ransomware can lock users out of their devices or data until a ransom is paid.
  3. Botnets and DDoS attacks 
    Compromised IoT devices can be enlisted into botnets—networks of infected devices controlled by attackers. Botnets can be used to launch Distributed Denial of Service (DDoS) attacks, overwhelming targets with massive traffic and causing significant disruptions.
  4. Physical tampering 
    Physical access to IoT devices can lead to tampering, where attackers can alter device configurations, install malicious hardware, or extract sensitive data.
  5. Vulnerabilities and exploits 
    IoT devices often suffer from software vulnerabilities that attackers can capitalize on. These vulnerabilities may arise from insecure coding practices, lack of regular updates, or insufficient testing.
  6. Privacy concerns 
    Unauthorized access to data collected by devices can lead to privacy breaches, identity theft, and unauthorized surveillance.
  7. Supply Chain Attacks 
    Malicious actors can compromise devices at various stages of the supply chain, embedding malicious code or hardware that can be activated post-deployment.
