A screened subnet typically segregates public-facing services from internal networks and does not directly prevent social engineering attacks like whaling against internal users.

A firewall can help limit the risk of whaling attacks by blocking access to known malicious websites and command-and-control servers that might be linked from a whaling email or become active after an initial compromise. It acts as a critical network security control that can prevent the execution or spread of malware resulting from a successful social engineering attempt, thereby limiting potential damage.

Anti-phishing training is highly effective at preventing users from falling victim to whaling attacks, but a firewall provides a technical, network-level implementation to block malicious traffic and mitigate the effects of an attack.

Antivirus software protects against known malware signatures, but whaling attacks primarily exploit human trust and often don't involve direct execution of traditional virus files as the initial vector.
