5 minutes 5 Questions

Email and messaging security aims to protect an organization's electronic communications from unauthorized access, malware, phishing attacks, and spam. Given that email serves as a primary communication medium for most organizations, it is vital to safeguard the messages, attachments, and users from potential risks. By employing server and client-side mechanisms such as email encryption, secure message transmission, strong authentication, anti-spam, anti-malware, and anti-phishing technologies, organizations can secure their email and messaging systems. Email and messaging security measures can prevent data leakage, protect the organization's reputation, and maintain compliance with various data privacy regulations. A robust email and messaging security plan helps ensure that an organization's electronic communications remain confidential, authentic, and available to authorized users.

Question 1

A user receives an email that appears to be from a bank requesting sensitive account information. Which of the following security measures can help prevent this type of attack?

Establish email usage policies Disable attachments in email clients Implement email content filtering Enable Secure Socket Layer (SSL) encryption

Correct Answer: Implement email content filtering

Email content filtering can detect and block emails containing harmful content or links, such as phishing attempts. While SSL encryption helps protect the content of emails during transmission and email usage policies can guide users, they do not prevent phishing emails from arriving. Disabling attachments, using email forwarding, and validating sender addresses also do not directly address phishing content in emails.

Question 2

A company needs to archive all ingoing and outgoing email communications for compliance reasons. Which of the following would be the most effective method for achieving this?

Use a cloud-based spam filter to archive emails Configure email clients to export emails to an external storage Implement email archiving on the email server Manually archive all emails on a regular basis

Correct Answer: Implement email archiving on the email server

Implementing email archiving on the email server enables automatic and centralized archiving of all ingoing and outgoing email communications. Manual archiving, configuring email clients, cloud-based spam filtering, forwarding, and server backups are not effective methods for ensuring complete and compliant email archiving.

Question 3

An employee receives an email with a PDF attachment that claims to contain an invoice. The employee was not expecting an invoice. What action should be taken before opening the attachment?

Reply to the sender asking for more details Print the email and open the attachment Scan the attachment with an up-to-date antivirus software Forward the email to a colleague

Correct Answer: Scan the attachment with an up-to-date antivirus software

Scanning the attachment with an up-to-date antivirus software ensures that the attachment is free from known viruses and malicious software. Forwarding, replying, printing, opening, or saving the email does not necessarily protect against potential threats contained within the attachment.
