Question

An accountant needs to send an email with sensitive information to a client and wants to prevent someone from reading the email if it is intercepted in transit. The client's email system does not allow them to receive attachments due to their company security policies. Which of the following should the accountant use to send the email?

answer

Host-based firewall


Cipher text


File level encryption


Plain text

Answer 1

In this scenario, since the accountant needs to send an email with sensitive information and wants to prevent interception, the best option would be to use **Cipher text**.

Cipher text refers to data that has been encrypted and is not readable without the proper decryption key. Using cipher text ensures that even if the email is intercepted during transit, it would be unreadable to anyone without access to the decryption method.

- A **host-based firewall** does not secure the email itself; it only controls network traffic.
- **File level encryption** involves encrypting data in files, which isn't applicable here since no attachments can be sent.
- **Plain text** is not secure and can easily be read if intercepted.

Therefore, the best choice is **Cipher text**.
