Chapter 6 : How To Secure And Authenticate Customers’ Emails
The Need For Email Authentication
Email authentication is necessary to block fraudulent uses of emails such as phishing and spam. It also ensures that the sender’s credentials are genuine and that the contents have not been tampered with during transit.
Ensure Successful Delivery Of The Emails To The Respective Clients
Email authentication provides more confidence to the mailbox provider that the emails sent are genuine. Thus, it ensures successful delivery of the emails to the client’s inbox instead of ending up in the spam folder.
Use Consistent Mail Sender Address
Using a consistent email address allows the receiver to recognize the sender as a trusted brand. Frequent changing of the names and addresses can send suspicious signals and train recipients to be susceptible to phishing attacks.
Authenticate IP Addresses With SPF
SPF compares the email sender’s IP address with the list of addresses authorized to send emails from the specific domain. Thus, it authenticates the IP address as genuine.
Configure DKIM Signatures For Messages
DKIM is an authentication standard that provides the recipient servers with the confidence that there is no tampering of the email message in transit. It cryptographically signs them to facilitate authentication.
Protect The Domain With DMARC Authentication
DMARC is a protocol that uses both SPF and DKIM to prevent cyber adversaries from spoofing an email address.
Prepare For BIMI
‘Brand Indicators for Message Identification’ or BIMI adds extra authentication to provide the element of trust to the recipient. BIMI allows senders to include their brand’s logo in the inbox for easy identification.
The Role Of SPF And DKIM In Email Authentication
SPF compares the sender’s IP address with the authorized list provided to it to ensure that the email has originated from a genuine domain. DKIM cryptographically signs the emails to certify that there has not been any tampering in transit.
