Special Issue Information

Dear Colleagues,

The topic of "Cybersecurity and Internet of Things (IoT)" encompasses the intersection of two critical areas in the modern digital landscape. Cybersecurity focuses on safeguarding systems, networks, and data from digital attacks, unauthorized access, and malicious activities, aiming to protect the confidentiality, integrity, and availability of information.

In the context of IoT, which refers to the network of physical devices embedded with sensors, software, and connectivity that enable them to collect and exchange data, cybersecurity plays a pivotal role in ensuring the secure operation and communication of these interconnected devices. 

The increasing integration of IoT devices into various aspects of daily life, including smart homes, healthcare systems, industrial automation, and transportation, has amplified the importance of addressing cybersecurity challenges within the IoT ecosystem. This includes considerations for securing device communication, data encryption, access control, authentication, and resilience against potential cyber threats. Moreover, the vast amount of data generated by IoT devices poses additional cybersecurity concerns, such as data privacy, data integrity, and protection against unauthorized access. 

The topic of "Cybersecurity and Internet of Things (IoT)" delves into the critical strategies, technologies, and best practices essential for ensuring the security and integrity of interconnected devices and the data they generate, ultimately contributing to the establishment of a trustworthy and resilient IoT environment in the digital era.

The trend in self-tracking devices has remained unabated for years. Even if they record a large quantity of sensitive data, most users are not concerned about their data being transmitted and stored in a secure way from the device via the companion app to the vendor’s server. However, the secure implementation of this chain from the manufacturer is not always given, as various publications have already shown. Therefore, we first provide an overview of attack vectors within the ecosystem of self-tracking devices. Second, we evaluate the data security of eight contemporary fitness trackers from leading vendors by applying four still partly standards-compliant Bluetooth Low-Energy Man-in-the-Middle (MitM) attacks. Our results show that the examined devices are partially vulnerable against the attacks. For most of the trackers, the manufacturers put different security measures in place. These include short and user-initiated visibility and connectivity or app-level authentication to limit the attack surface. Interestingly, newer models are more likely to be attackable, underlining the constant need for verifying the security of BLE devices, reporting found vulnerabilities, and also strengthening standards and improving security awareness among manufacturers and users. Therefore, we finish our work with recommendations and best practices for law- and regulation-makers, vendors, and users on how to strengthen the security of BLE devices. Full article
