A consultant frequently travels and occasionally needs to use their smartphone to provide an internet connection to their laptop. To mitigate security risks, which setup would be the MOST effective when configuring the smartphone's hotspot for secure access?
Implement MAC address filtering to allow only the laptop's MAC address to connect
Use WPA3 or WPA2 with a strong, unique password for the laptop's connection
Restrict the number of devices that can connect to the hotspot to one
Configure the hotspot as an open network to avoid the hassle of passwords
Creating a strong, unique password using a combination of letters, numbers, and symbols is essential for securing a hotspot connection and mitigating unauthorized access. MAC filtering adds an additional layer of security by only allowing access to the laptop with a specific MAC address. However, since MAC addresses can be spoofed, relying solely on MAC filtering is less secure than using WPA2 or WPA3 with a strong password. Open networks are vulnerable to any nearby device, which is a significant security risk. Restricting the number of connected devices alone does not inherently secure the network as any device within that limit could connect.
