A. B. C. D.C.
Phishing is a way of attempting to acquire information such as usernames, passwords, and credit card details by masquerading as a trustworthy entity in an electronic communication.
Phishing attacks are a type of to social engineering attack and are best defended by end-user awareness training.
Incorrect Answers: A: An intrusion detection system does not protect against phishing attacks since phishing attacks usually do not have a particular pattern or unique signature.
B: Application hardening does not protect against phishing attacks since phishing attacks generally use e-mail as the attack vector, with the end-user as the vulnerable point, not the application.
D: Certain highly specialized spam filters can reduce the number of phishing e-mails that reach the inboxes of user, but they are not as effective in addressing phishing attack as end-user awareness.
The BEST defense against successful phishing attacks is end-user awareness (Option C).
Phishing attacks are a social engineering technique where the attacker tricks the victim into clicking on a malicious link or downloading a malware-laden attachment. In such attacks, the attacker may pose as a trustworthy entity, such as a bank, an email provider, or a social media platform, to lure the victim into providing sensitive information or taking an action that compromises their security.
End-user awareness is the most effective defense against phishing attacks because it educates individuals on how to recognize and avoid phishing attempts. It teaches them to be vigilant and cautious when dealing with unsolicited emails or messages, to scrutinize the sender's details and email content, and to avoid clicking on suspicious links or downloading unknown attachments.
While other options such as intrusion detection systems, application hardening, and spam filters can complement end-user awareness, they do not provide a comprehensive defense against phishing attacks.
Intrusion detection systems can alert the organization of potential attacks, but they cannot prevent users from falling for phishing attempts. Similarly, application hardening can secure the applications against known vulnerabilities, but it cannot protect against novel attack techniques or user errors. Spam filters can block a significant amount of spam emails, but they may not detect sophisticated phishing emails that can bypass the filters.
Therefore, end-user awareness should be a cornerstone of any organization's defense against phishing attacks, coupled with other technical controls and policies to mitigate the risk of successful attacks.
