A company's IT policies require that any wireless access for non-employees must be strictly controlled and monitored. As the network administrator, you have been tasked with configuring the wireless access point to align with this policy. What is the most effective action to take that allows for occasional, secure guest use without providing continuous open access?
Increase the Wi-Fi encryption level, which requires more complex passwords for guest access.
Enable a guest network with its own authentication mechanism that is separate from the internal network.
Disable the DHCP server to prevent unauthorized devices from obtaining an IP address.
Implement MAC address filtering to allow only pre-approved devices to access the network.
Enabling a guest network with a separate password that can be changed regularly allows for controlled and temporary access for guests without compromising the security of the main network. It is crucial to avoid providing guests with access to the primary network credentials. MAC address filtering is not effective as MAC addresses can easily be spoofed. Disabling the DHCP server would prevent all wireless devices from obtaining IP addresses automatically, which would disrupt network connectivity for authorized users.
