What is Wireless security?

Understanding Wireless security

Wireless security involves a collection of strategies, safeguards, and standards designed to protect wireless connections from unauthorized use and hostile actions. Because data is transmitted through open air rather than through a wired path, additional security layers are crucial to guard against eavesdropping, interference, and other illicit activities. These protective measures range from robust encryption protocols—such as WPA2 or WPA3 for Wi-Fi networks—to specialized authentication requirements and continuous monitoring systems that detect unusual traffic or potential breaches.

Wireless security covers a variety of technologies, including Wi-Fi, cellular networks, and Bluetooth communication. Ensuring strong, up-to-date defenses helps maintain the confidentiality, integrity, and availability of information passed across the network. In broader contexts, wireless security measures often align with general security frameworks or industry standards to reinforce trust and safety. For related concepts, see Bluetooth.
