A company wants to implement a solution to prevent phishing emails from reaching employee inboxes. Which of the following should the technician configure?

While firewall rules play a significant role in network security by controlling incoming and outgoing traffic, they are not specifically designed to filter email content. Firewalls primarily protect networks from unauthorized access and attacks but do not address the specific issue of phishing emails, which require more specialized filtering solutions.

Antivirus software is vital for detecting and removing malware from systems but serves a different purpose than email filtering. Although some antivirus programs offer email scanning features, they are not primarily focused on preventing phishing emails from reaching inboxes. Their primary function is to protect devices from malicious software that may be delivered via email.

Configuring DNS settings can enhance security by preventing access to known malicious domains, but this approach does not directly filter incoming emails. DNS settings help direct internet traffic effectively and can block certain threats, yet they do not address the specific challenge of identifying and filtering phishing attempts in email communications.
