A finance department employee has received a message that appears to have been sent from the Chief Financial Officer (CFO), asking the employee to perform a wire transfer.
Analysis of the email shows the message came from an external source and is fraudulent.
Which of the following would work BEST to improve the likelihood of employees quickly recognizing fraudulent emails?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
The best way to improve the likelihood of employees quickly recognizing fraudulent emails is to educate them about the signs of fraudulent emails and provide them with training on how to identify them. However, out of the given options, the most effective would be option D: adding a banner to incoming messages that identifies the messages as external.
This solution would help to increase awareness among employees and remind them to be more cautious when receiving emails from external sources. The banner could also be customized to include additional information or warnings about the risks associated with opening emails from unknown sources.
Option A, implementing a sandboxing solution for viewing emails and attachments, may help prevent the spread of malware or viruses, but it would not necessarily help employees recognize fraudulent emails.
Option B, limiting email from the finance department to recipients on a pre-approved whitelist, would not be practical in most organizations and would not address the broader issue of fraudulent emails.
Option C, configuring email client settings to display all messages in plaintext when read, may help prevent phishing attacks that rely on embedded links or scripts, but it would not necessarily help employees recognize fraudulent emails that use social engineering techniques to deceive recipients.
Overall, the best approach to preventing fraudulent emails is to implement a comprehensive security awareness program that includes employee training, regular phishing simulations, and the use of technical controls such as spam filters and email authentication protocols like DMARC, DKIM, and SPF.
