The Main Vulnerabilities and Security Risks within IoT Devices



Here at Iotabl, we love the Internet of Things (IoT). The application of these interconnected devices that exchange data between themselves, and systems over the Internet or other communications networks, is vast and exciting. Our favourite smart home speaker is the (heart)beat of our home. Without a water quality monitor, how else can utility firms ensure the water we consume is of the right quality? Both examples of IoT devices are adopted in different industries to benefit our lives.


However, it’s not all sunshine and roses. Though the impending surge in the adoption of IoT devices will further the technology capabilities of beneficiaries around the world, the increase in attack surfaces on these devices from malicious actors will follow suit. Exploits can be attacked within endpoint devices (speakers, cameras) or from the software and hardware adopted inside the product.


Below are six IoT vulnerabilities and threats to be aware of:


1. Insecure ecosystem interfaces

Application programming interfaces (APIs) can open the doors for attackers to access a firm’s IoT devices and exploit its server, web interface, network router, etc.


2. Weak passcodes (DUH!)


3. Botnets

The series of internet-connected devices created to compromise networks, steal data or send spam. Containing malware, Botnets enable attackers to infiltrate an organisation’s network through access to IoT devices – a huge threat for businesses.


4. Unaware of IoT devices in the network

You can only manage what you see. Significant IoT devices remain untracked, unmonitored, and improperly managed. Lacking visibility into device status can prevent companies from detecting and responding to potential threats.


5. Insecure data storage

As the adoption of cloud-based communications and data storage increases, as do the cross-communication between smart devices and the IoT network. However, there is a lack of encryption and access controls before data is entered into the IoT ecosystem. As a result, as data is transferred and stored through such networks, potential breaches, or data compromises surge.


6. Lack of physical hardening

As most IoT devices are remotely deployed, it is difficult to secure devices that are constantly exposed to the broader physical attack surface. Without a secure location and lacking continual support, devices are exposed to potential attackers who can gain valuable information about their network’s capabilities and, as a result, assist in future remote attacks


With our risk-mitigation platform, we seek to empower companies with a greater understanding of their IoT network, devices, and software supply chains. As a result, putting cyber security in their own hands, giving them the knowledge and tools to innovate.
