Question 1

What are SPF, DKIM, and DMARC?

Accepted Answer

SPF (Sender Policy Framework) specifies which mail servers are authorized to send email for your domain. DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails so recipients can verify the message was not altered. DMARC (Domain-based Message Authentication, Reporting and Conformance) ties SPF and DKIM together with a policy that tells receiving servers what to do when checks fail — reject, quarantine, or allow.

Question 2

Why do attackers use phishing emails?

Accepted Answer

Phishing is one of the most effective attack vectors because it exploits human trust rather than technical vulnerabilities. A well-crafted phishing email can trick users into revealing credentials, clicking malicious links, or downloading malware. Over 80% of security incidents involve some form of phishing, making it a critical threat to understand and defend against.
