Did you know that your Wi-Fi connection uses one of four different security types? While they are all different, they are not all the same; Thus, it is necessary to learn which security type your Wi-Fi is using.

Let’s explore the four Wi-Fi security types and see which ones are the best to use.


What Are the 4 Wi-Fi Security Types?

1. The Wired Equivalent Privacy (WEP) Protocol

WEP is the oldest security type to enter the computing world in 1997. Due to its age, it is still practiced in older systems in the old age. Of all the protocols, WEP is considered the least secure.


2. The Wi-Fi Protected Access (WPA) Protocol

Wi-Fi Protected Access or WPA was introduced to correct the inherent weaknesses of the WEP. Although it improves safety, it has its own problems. The encryption key used by the WPA depends on a passphrase, service set identification name (SSID), SSID length, and a random value. Most of the information used to create this 256-bit key is easily known, so a hacker would only have to guess the passphrase for access to the network. Dictionary attacks systematically tried several combinations of words, characters, and phrases to infer this passphrase. It was determined that a passphrase with less than 20 characters could be defeated.


3. The Wi-Fi Protected Access 2 (WPA2) Protocol

WPA2 is the successor to WPA and brings more features into the mix. This replaced TKIP with the Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP), which worked better with encrypted data.


4. The Wi-Fi Protected Access 3 (WPA3) Protocol

WPA3 is the new kid on the block, and you can find it in Routers produced in 2019. With this new format, WPA3 brings improved encryption to public networks to prevent hackers from harvesting information from them. It is also easy to connect to a WPA3 router with a device with no display, and has some additional features that protect against brute force attacks. It is likely to be the new WPA standard in the future, so it is a good idea to find out everything you need to know about WPA3.
