Question

The Chief Executive Officers (CEOs) from two different companies are discussing the highly sensitive prospect of merging their respective companies together. Both have invited their Chief Information Officers (CIOs) to discern how they can securely and digitally communicate, and the following criteria are collectively determined:

Must be encrypted on the email servers and clients
Must be OK to transmit over unsecure Internet connections.

Which of the following communication methods would be BEST to recommend?

A. Force TLS between domains.
B. Enable STARTTLS on both domains.
C. Use PGP-encrypted emails.
D. Switch both domains to utilize DNSSEC.

Answer 1

PGP-encrypted emails would be the best communication method to recommend.

Step-by-step explanation:

The BEST communication method to recommend in this scenario would be PGP-encrypted emails. PGP (Pretty Good Privacy) is a cryptographic protocol that allows for secure communication by encrypting the email content. When using PGP-encrypted emails, the email servers and clients are encrypted, ensuring that the content remains secure during transmission. This method meets both the criteria of encryption on the email servers and clients and being safe to transmit over unsecured Internet connections.
