What is wpa

It is a technology developed to secure internet access for Wi-Fi networks. Prior to this, WEP or Wired Equivalency Privacy was the only security technology available but was later upgraded since its authentication and encryption features were weak. Although conflict has risen since writing a new security specification would take up a lot of time and require a careful process.

The WPA was released in as an interim standard to answer the immediate need for a more secure protocol. With this, nobody can access which pages are visited and other information shared. Meanwhile, one of the upgrades provided in WPA was the incorporation of message integrity checks. This determines if someone has intercepted packets while it is being transmitted from an access point to the client. This is more secure than WEP's fixed key system since it uses a per- packet system.

This was primarily used to protect classified data of the US government. There are two types of WPA that cater to different users. This type is primarily used for small office use and for personal use at home. A bit authentication key is used for all wireless devices connected. You can get the WPA password from whoever runs the network. In some cases, a default WPA passphrase or password may be printed on a wireless router. If you can't determine the password on your router, you may be able to reset it.

However, WPA2 still has drawbacks. KRACK exploits a weakness in WPA2, which allows attackers to pose as a clone network and force the victim to connect to a malicious network instead. This enables the hacker to decrypt a small piece of data that may be aggregated to crack the encryption key.

WPA3 introduced new features for both personal and enterprise use, including:. Individualized data encryption : When logging on to a public network, WPA3 signs up a new device through a process other than a shared password. Simultaneous Authentication of Equals protocol : This is used to create a secure handshake, where a network device will connect to a wireless access point, and both devices communicate to verify authentication and connection. Stronger brute force attack protection : WPA3 protects against offline password guesses by allowing a user only one guess, forcing the user to interact with the Wi-Fi device directly, meaning they would have to be physically present every time they want to guess the password.

WPA2 lacks built-in encryption and privacy in public open networks, making brute force attacks a significant threat. WPA3 devices became widely available in and are backwards compatible with devices that use the WPA2 protocol.

Knowing your Wi-Fi encryption type is important for your network's security. Older protocols are more vulnerable than newer ones and, therefore, more likely to fall victim to a hacking attempt.

This is because older protocols were designed before it was fully understood how hackers attacked routers. The more recent protocols have fixed these exploits and are therefore considered to offer the best Wi-Fi security. Unfortunately, there is no way within iOS to check your Wi-Fi security. Each router may be different, so you may need to refer to the documentation that came with the device. Alternatively, if your internet service provider set up the router, you could contact them for assistance.

If a router is left unsecured, criminals could steal your internet bandwidth, carry out illegal activities through your connection, monitor your internet activity, and install malicious software on your network. The network name and key shouldn't be confused with the username and password, which are needed to access the router settings.

If the WPA key has been changed, reset your router to return the key to the default. The latest standard is WPA3 , which offers enhanced security for open networks. On Windows 10, select the Wi-Fi icon in the taskbar, select Properties under the network you're currently connected to, then look for the Security Type.

On a Mac, hold down the Option key and select the Wi-Fi icon in the toolbar to see your network details. On Android, go to your Wi-Fi connections and tap the network to see its details.
