Question 1

What is the primary purpose of email encryption?

Accepted Answer

To ensure only the intended recipient can read the email content

Answer

Email encryption converts email content into an unreadable format that can only be decrypted by the intended recipient, protecting the confidentiality of the message.

Question 2

Which type of email attack uses a fabricated sense of urgency to trick recipients into taking immediate action?

Accepted Answer

Social engineering through urgency-based phishing

Answer

Urgency-based phishing emails create artificial time pressure—such as threatening account suspension or missed deadlines—to override the recipient's critical thinking and prompt hasty action.

Question 3

What does SPF (Sender Policy Framework) do for email security?

Accepted Answer

Specifies which mail servers are authorized to send email for a domain

Answer

SPF is a DNS-based email authentication protocol that allows domain owners to specify which mail servers are authorized to send emails on behalf of their domain, helping prevent email spoofing.

Question 4

Why should you be cautious about clicking links in emails, even from known contacts?

Accepted Answer

The sender's email account may have been compromised and used to send malicious links

Answer

Even emails from known contacts can contain malicious links if the sender's account has been hacked, making it important to verify unexpected links before clicking.

Question 5

What is the purpose of a digital signature in email?

Accepted Answer

To verify the identity of the sender and ensure the message has not been altered

Answer

A digital signature uses cryptographic techniques to verify the sender's identity and confirm that the email content has not been modified during transit.
