What is DMARC Record?
DMARC record stands for Domain-based Message Authentication, Reporting, and Conformance. It is an email authentication protocol that helps organizations protect their email domains from unauthorized use, such as phishing and spoofing attempts. DMARC record works by allowing email domain owners to publish policies in their Domain Name System (DNS) records, which tell email receivers whether an incoming email is legitimate or not.
Why DMARC Record is Important?
Email is a critical communications channel for businesses, and it is also a primary target for cybercriminals seeking to gain access to sensitive information or spread malware. Phishing and spoofing attacks are two common tactics used by cybercriminals to impersonate legitimate businesses or deceive users into revealing their personal and financial information. DMARC record provides a way for businesses to protect their email domains from these types of attacks by enabling email receivers to verify the authenticity of incoming emails.
DMARC record is important for the following reasons:
How DMARC Record Works?
DMARC record operates on top of two existing email authentication protocols, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). SPF verifies the sender’s IP address against a list of authorized senders for a particular domain, while DKIM uses public-key cryptography to validate the authenticity of the sender’s message.
When an email receiver receives an email, it checks the sender’s IP address against the SPF record and validates the DKIM signature. DMARC record uses the results of these checks to determine the authenticity of the email. If the email passes both tests, it is considered legitimate, and if it fails, it is marked as spam or rejected entirely.
How to Implement DMARC Record?
DMARC record implementation requires a few steps:
Conclusion
DMARC record is a powerful email authentication protocol that provides businesses with an effective way to protect their email domains from unauthorized use and prevent email-based fraud and cyberattacks. By implementing DMARC record, businesses can maintain a positive reputation, increase email deliverability, and gain valuable insights into their email ecosystem.
