Secure Emails with SPF, DKIM and DMARC Records

Email is the prime target for hackers.  At the very basic level, we need to protect our Email systems by making the required Updations at the DNS Level. We have seen that in many User Organizations, the basic Email records are not updated.

Given below are some important records that you need to ensure are correctly updated:

1. SPF Record

Sender Policy Framework is an email authentication method designed to detect forging sender addresses during the delivery of the email. When used in combination with DMARC can it be used to detect the forging of the visible sender in emails, a technique often used in phishing and email spam.

2. DKIM Record

Domain Keys Identified Mail (DKIM) record is used for Email Security. It gives emails a signature header that is added to the email and secured with a public/private key pair and a Certificate. It helps in strengthening authenticity of your email. It is a process of signing your email with a digital signature for proving authenticity.

3. DMARC Record

The Domain-based Message Authentication, Reporting, and Conformance (DMARC) record is a record your sending server uses to securely communicate with receiving email servers. It works with Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate mail senders and ensure that destination email systems trust messages sent from your domain. Implementing DMARC with SPF and DKIM provides additional protection against spoofing and phishing email. DMARC helps receiving mail systems determine what to do with messages sent from your domain that fail SPF or DKIM checks.
