A Review of Forensics Security Hazards and Challenges in WBAN and Healthcare Systems
S. Karthika, K. Juliana Gnanaselvi · 2024
Wireless sensors affixed to the body or implanted are used by wireless networks, also known as Wireless Body Area Networks (WBANs). Because WBANs are focused on medical equipment, the system must be designed to accommodate a wide variety of end users with various specialized skills. To enhance people’s quality of life, a new technology called WBAN is being utilized to monitor the patients inside and outside of the hospitals, in sporting events, military environments, and many other contexts. WBANs consist of smart nano or micro sensors that process data and communicate with a base station (BS). Thanks to sensors placed on the body, people can provide important information wirelessly. Due to the need for online medical information, consumers are concerned about the security of their personal information. Medical information security is important and difficult, as both active and passive threats can be made. Businesses and government agencies must now comply with laws and regulations to prevent data breaches. WBANs continue to be a major problem, among other vulnerabilities discovered, which competitors can easily exploit in the medical field. For this reason, it is important to identify the vulnerabilities of WBAN systems and create effective protection. WBAN is built based on BodyNet, which allows sensor nodes to monitor physiological composition and body movement over a wireless network. Its purpose is to help doctors monitor patients remotely by changing the connection of the cell phone sensor. This study examines WBANs, security issues, physical sensor network architectures, and communication technologies. We conducted a risk assessment (Practical Impact Assessment [PIA]) in a real situation to discuss potential WBAN security vulnerabilities and threats to identify issues and improve protection and monitoring accurately. This allows us to create secure network architecture for forensic-ready WBAN systems.
