It works by using formulas known as algorithms to scramble messages as they travel between wireless devices. These include wireless access points ( APs) communicating with a controller device (or, on a mesh network, with each other), as well as communications between APs and endpoints connected to the Wi-Fi network.Įncryption is one of the most important tools used to create a secure network, including - and perhaps especially - in a wireless LAN. In contrast, wireless security primarily concerns itself with traffic that travels over the air between wireless devices. Wired network security protects traffic that travels between devices like switches, routers and anything using an Ethernet cable. Technology enforces those rules and protects the network from anyone, or anything, that attempts to breach it.
Broadly speaking, wireless security articulates which endpoints are and aren't permitted on a Wi-Fi network through network access and security policies. 12 types of wireless network attacks and how to prevent themĮnter wireless network security - a set of practices and tools used to protect WLAN infrastructure and the traffic that traverses it.Wireless network capacity planning and requirements.A history of wireless for business and a look forward.This article is part of What is wireless communications?
