Wi-Fi Protected Setup (WPS) consists of four modes that enable the addition of devices to a network. Which mode is associated with major security risks as a result of a brute-force exploit?

In 2011, it was discovered that WPS (Wi-Fi Protected Setup) personal identification numbers (PINs) posed a security risk due to a practical brute-force attack against WPS PIN setup modes. Besides this, WPS has several other security problems and is not utilized for enterprise security. However, WPS is still popular in home environments because of its ease of installation.

There are a few ways to mitigate the security risks associated with WPS:

• Disable WPS: If the WPS functionality is not necessary, disabling it is the easiest and most effective way to eliminate the associated security risks.
• Use the push-button method: WPS offers a push-button option that allows devices to be added to the network without the need for a PIN. This method is more secure than using a PIN because it is not susceptible to brute-force attacks.
• Use a strong and unique WPS PIN: If using a PIN is necessary, it is essential to use a strong and unique PIN that is not easily guessable. Some routers allow users to change the default PIN to a custom one.
• Keep the router firmware up to date: Router manufacturers frequently release firmware updates that address security vulnerabilities, including those related to WPS. Keeping the router firmware up to date can help mitigate security risks associated with WPS.
