Wireless security is a research field and academic concept dedicated to understanding and mitigating the unique security risks inherent in wireless communication technologies and networks. It investigates vulnerabilities arising from the broadcast nature of wireless signals, potential threats such as eavesdropping, unauthorized access, and denial-of-service attacks, and develops protocols, algorithms, and methodologies to ensure the confidentiality, integrity, and availability of data and systems operating in wireless environments. Its significance lies in protecting sensitive information and critical infrastructure in an increasingly interconnected world reliant on wireless connectivity.
