Hello everyone!
In this article, I'll share some basics about WiFi security, and I'll also share my views on which type of security you should choose.
Wireless Security Type
WEP
WEP stands for Wired Equivalent Privacy and was the first WiFi security protocol approved in September 1999. It was initially expected to provide the same level of security as a wired network. The second function of WEP is said to be to prevent unauthorized access to the wireless network.
However, cryptanalysts have identified several weaknesses in WEP, so it was obsoleted by WiFi Protected Access (WPA) in 2003 and replaced by the full IEEE 802.11i standard (also known as WPA2) in 2004. WEP has some weaknesses, but it's enough to deter non-professional snooping.
WPA
WPA, called WiFi Protected Access, has three standards: WPA, WPA2, and WPA3, and is a system that protects the security of wireless computer networks (WiFi). It arises in response to several serious weaknesses found by researchers in the previous generation of System Wired Equivalent Encryption (WEP). WPA implements most of the IEEE 802.11i standard and is a transition solution to replace WEP before 802.11i is complete. WPA is designed to work with all wireless cards, but not necessarily with first-generation wireless access points.
WPA2
WPA2 (WPA version 2) is the WiFi Alliance's certification program for products that incorporate IEEE 802.11i security enhancements. Simply understood, WPA2 is a new encryption mode based on WPA. Most enterprises and many new residential WiFi products support WPA2. As of March 2006, WPA2 has become a mandatory standard. WPA2 requires chipsets with Advanced Encryption Standard (AES) to support it.
WPA2 is available in two styles: WPA2 Personal Edition and WPA2 Enterprise Edition. WPA2 Enterprise requires a RADIUS (Remote User Dialing Authentication System) server with IEEE 802.1X capability.
WPA3
I have already shared an article about WPA3 on the forum. I won't repeat the introduction here. Interested friends can click WPA3 for more information.
WPS
In 2007, a new method of security, WiFi Protected Settings (WPS), began appearing on wireless access points. Its main purpose is to simplify the security encryption configuration of wireless networks. WPS technology is used to help users automatically set the network name (SSID) and configure the highest level of WPA2 security key.
With this type of security, users can add a new device to their network by pressing a button (in the management software or on the router) and entering an 8-digit PIN on the client device.
Suggestions on WiFi Security Type Selection
Don't use WEP, it's easy to crack.
Do not use WPA unless older devices on your network require WPA.
It's best not to use WPS, it's easy to brute force crack.
Make sure you use at least WPA2 with a strong password
Of course, the latest version of WP3 is by far the best choice.
