ユーザーの職場の PC が複数のフィッシング攻撃の標的になりました。ユーザーがさらなる攻撃を防ぐ方法は次のうちどれですか?
正解:B
Phishing attacks are typically delivered via email, so the most effective immediate measure is to filter out these malicious emails. * Enabling Windows Firewall: Helps protect against network threats but does not specifically address phishing emails. * Activating the email spam filter: Directly targets phishing attempts by filtering and blocking suspicious emails before they reach the user. * Using a secure VPN connection: Enhances secure communications but does not prevent phishing attacks. * Running vulnerability scans on a schedule: Identifies and mitigates vulnerabilities but does not address phishing emails directly.
