Explanation

DNS filtering blocks access to malicious domains by preventing DNS resolution of known bad sites, protecting users from phishing and malware even if they click on harmful links. Updating ACLs to allow only HTTPS doesn't stop access to malicious HTTPS sites. IPS (Intrusion Prevention System) helps with network-level threats but may not directly prevent users from resolving or visiting phishing domains. 802.1X controls network access at the port level, not web traffic or DNS-level filtering. DNS filtering is the most effective and targeted measure to prevent access to malicious websites.
