A security architect wants to prevent employees from receiving malicious attachments by email. Which of the following functions should the chosen solution do?
C. Scan email traffic inline.
Inline scanning is the most effective method to prevent malicious attachments from reaching employees' inboxes. By scanning emails in real-time, as they are being delivered, the security solution can identify and block malicious attachments before they reach the user's device.
SPF records are used to verify the sender's identity, but they do not prevent malicious attachments
Only scanning the inbox can detect and protect the malicious attachment.
* Detect Malicious Attachments: SPF (Sender Policy Framework) does not scan or analyze the content of emails, including attachments.
* Block Phishing or Malware: SPF only verifies the sender's server, not the safety of the email's content.
The correct answer is:
C. Scan email traffic inline.
Explanation:
To prevent employees from receiving malicious attachments via email, the solution should scan email traffic inline. This involves scanning email messages, including attachments, as they pass through the mail server. By scanning emails inline, the system can identify and block malicious attachments before they are delivered to the user's inbox. This type of solution often includes antivirus and anti-malware scanning for email content.
