Wireless security consists of the policies and procedures put in place to safeguard wireless networks, the information transferred through them, and any risks to safety. As wireless networks grow in popularity, it is crucial to be educated on how to secure them in order to fend off possible threats, and preserve data privacy, and integrity.
How Does Wireless Security Work?
Data traveling between switches, routers, and other equipment attached by Ethernet cables is protected by wired network security. Contrary to popular belief, wireless security mainly deals with safeguarding information sent between wireless devices using radio waves. This broad category covers mobile access points that are in conversation with a device that acts as a controller or with one another inside a mesh network. Additionally, it includes the interactions that take between the access points and endpoints that are linked to the Wi-Fi network.
Encryption is of utmost importance in developing a secure network, especially in the context of wireless local-area networks. As a cornerstone, encryption uses complex algorithms to hide public messages as they travel between various wireless devices. These encrypted messages are inaccessible to unauthorized parties without the necessary decryption key, even when they are intercepted. This adds an extra layer of security to the information being transferred.
Wireless encryption protocols have changed throughout time in light of dynamic changes in network requirements, the introduction of security concerns, and the discovery of weaknesses ingrained in earlier encryption techniques.
Examples of Wireless Security Protocols
- WPA (WiFi-Protected Access)
- WEP (Wired Equivalent Privacy)
WPA3 is proven to be the best wireless security measure among the others but, WPA2 is recommended if WPA3 is not available.
