Question
A financial analyst is expecting an email containing sensitive information from a client. When the email arrives the analyst receives an error and is unable to open the encrypted message. Which of the following is the most likely cause of the issue?
A. The S/MIME plug-in is not enabled
B. The SSL certificate has expired
C. Secure IMAP was not implemented
D. POP3S is not supported
Answer
A. The S/MIME plug-in is not enabled
Explanation
The most likely cause of the financial analyst being unable to open the encrypted email is:
A. The S/MIME plug-in is not enabled
S/MIME (Secure/Multipurpose Internet Mail Extensions) is an email encryption standard that requires a plug-in to be installed and enabled in the email client. If the plug-in is not enabled, the email client will not be able to decrypt the encrypted message, resulting in an error.
The other options are less likely to be the cause:
B. SSL certificate expiration would affect the secure connection between the email client and server, but not the ability to decrypt an encrypted message.
C. Secure IMAP is used for retrieving emails securely but does not directly impact the decryption of encrypted messages.
D. POP3S is a secure version of POP3 for retrieving emails but is not related to the decryption of encrypted messages.
In summary, the most probable cause of the analyst’s inability to open the encrypted email is the S/MIME plug-in not being enabled in their email client.
