Which protocol is often employed to secure wireless networks for guest access?

1. PPTP

2. IPSec

3. WPA2

4. SSL

The correct answer is: WPA2

WPA2, which stands for Wi-Fi Protected Access II, is widely used to secure wireless networks, particularly for guest access. This protocol provides strong encryption and authentication methods, making it a go-to choice for most organizations looking to protect their wireless communications. WPA2 uses Advanced Encryption Standard (AES), offering robust data protection against unauthorized access and eavesdropping, which is particularly important when allowing guests on a network. WPA2 not only secures the connection but also supports different modes of access, enabling tailored guest management while maintaining the integrity of the primary network. The use of Pre-Shared Keys (PSK) or enterprise-level security such as 802.1X further enhances its usability for guest networks, permitting different access levels and ensuring that guests only have access to designated resources without compromising security. In contrast, other protocols such as PPTP and IPSec are primarily focused on securing VPN connections rather than wireless guest access. SSL (Secure Sockets Layer) is mainly utilized for securing connections over the internet, such as those used in web browsers, rather than being specifically designed for wireless network security. Therefore, when it comes to securing wireless networks designated for guests, WPA2 stands out as the most appropriate and effective choice.
