DomainKeys Identified Mail is a method of email authentication that allows the receiver to verify that an email message was sent by an authorized sender and has not been tampered with during transit. This is done by using public-key cryptography to sign outgoing messages, with the receiving server verifying the signature against a public key published in DNS.

38
Q

SPF

A

Sender Policy Framework
Another email authentication method that helps prevent email spoofing by verifying that sender’s IP address is authorized to send email for a particular domain. SPF records are published in the DNS and specify which IP addresses are allowed to send email on behalf of the domain

39
Q

Test question mentioned by peer: Something like you need an IP address and configured for a computer you’re adding to the network **

A

DHCP

40
Q

DMARC

A

Domain-based Message Authentication, Reporting, and Conformance is a more advanced email authentication protocol that combines the use of DKIM and SPF records to provide greater visibility and control over email authentication. DMARC policies are also published in DNS and allow domain owners to specify how receivers should handle email that fails authentication checks. For example, DMARC policies can instruct receivers to quarantine or reject suspicious email.

41
Q
