What should be implemented to increase the security of a wireless network in a small office setting?

Implementing the disabling of SSID broadcast is an important step in increasing the security of a wireless network in a small office setting. When SSID broadcast is disabled, the network name is not publicly advertised, meaning that devices will not show the network in the list of available networks to those who are scanning for Wi-Fi. This adds a layer of obscurity that can deter casual users or potential attackers from attempting to connect, as they would need to know the SSID in advance to join the network.

While disabling SSID broadcast can improve security to some extent, it's important to understand that it should be part of a broader security strategy. Security measures such as implementing robust encryption (like WPA3), changing default credentials, and using strong passwords should also be utilized alongside it for effective security.

The other options are related to network management and optimization rather than directly enhancing security. For example, changing default credentials is essential for securing network devices, but it does not specifically address the visibility of the network itself. Enabling Quality of Service (QoS) management helps prioritize network traffic but does not contribute to security. Modifying DHCP settings can help manage IP address assignments but does not directly impact the security of the network.

Thus, disabling SSID broadcast is
