An Extensive Review of Security Challenges in Wireless Body Area Networks.
TL;DR
The need to implement multilayered security frameworks, integrating strong encryption, authentication mechanisms, and advanced anomaly detection mechanisms to safeguard WBAN systems is emphasized, focusing on security in WBAN.
Abstract
Wireless body area networks (WBANs) became one of the most pioneering technologies in the medical sector and are known for continuous health monitoring and real-time medical data transmission. However, holding a secure WBAN environment is crucial to protect health-sensitive data and patient privacy from various cyber threats. This article serves as a comprehensive survey of potential security risks, focusing on security in WBAN. A detailed taxonomy of possible attacks is introduced, categorizing threats based on fundamental security services: authenticity, integrity, confidentiality, availability, and nonrepudiation. To alleviate these challenges, an in-depth classification of countermeasures has been provided, portraying detection mechanisms and defense strategies. This article emphasizes the need to implement multilayered security frameworks, integrating strong encryption, authentication mechanisms, and advanced anomaly detection mechanisms to safeguard WBAN systems. Moreover, this study serves as a foundation for future research on enhancing resilience in WBAN technologies.
