A company wants to ensure their employees do not access gambling sites during work hours from corporate devices. The network administrator is tasked with enforcing this policy using security features available on the organization's network firewall. Which of the following actions would most effectively meet this requirement?
Enforce network access control (NAC) to restrict all unauthorized devices from the network.
Disallow the use of mobile devices on the company network.
Configure URL-filtering rules on the network firewall to block websites categorized as gambling.
Update the firmware of the network firewall to the latest version.
Configuring URL-filtering rules on the firewall to block the Gambling content category ensures that any HTTP or HTTPS request to sites classified as gambling is denied. URL filtering evaluates outbound web requests against predefined category databases or custom lists and applies the block action specified in the policy. Updating firewall firmware and enforcing NAC improve security in other ways but do not directly stop users from reaching gambling sites. Disallowing mobile devices reduces exposure only if those devices are the access path; it does not address requests coming from approved corporate endpoints.
