Email is a critical communication tool that is used more frequently than ever before. However, attackers are increasingly using email to deliver malware, phishing scams, and other forms of cyberattacks. As such, it is essential for companies and individuals to safeguard their email accounts from unauthorized access and malicious activity. DMARC is a powerful email validation system that helps protect users from email fraud and phishing attacks. This article will introduce the DMARC framework, examine its objectives, and analyze its advantages for email security.

What is DMARC?
DMARC, Domain-based Message Authentication, Reporting and Conformance, is an email authentication protocol that allows domain owners to protect their domain from unauthorized use or fraudulent emails. DMARC does this by enabling an email recipient to validate whether an email message originates from the domain it claims to be from.
Objectives of DMARC
The primary objective of DMARC is to protect users from email fraud and phishing scams. DMARC accomplishes this by preventing unauthorized use of a domain by email spammers and cyber attackers. DMARC allows domain owners to define their email policies that must be enforced at the recipient’s end when an email is received. DMARC monitors emails sent using a domain, allowing the owner to see how their domain is being used online and allowing authorized users to validate the sources of the email.
Advantages of DMARC for Email Security
DMARC enables domain owners to specify what happens to email messages that fail SPF and/or DKIM, so that failed emails are no longer a security risk. Companies can use DMARC to prevent email-based impersonation attacks that could lead to phishing, malware, or ransomware infections. DMARC provides a clear indication of whether a domain is actively used for email and which messages are supported by the domain owner. This can help the domain owner protect their reputation and reduce chances of their domain being used for fraudulent activities. Additionally, DMARC’s reporting mechanism allows domain owners to analyze email traffic statistics and other useful information that can help them identify malicious activity.
How to Implement DMARC
Implementing DMARC requires the domain owner to add a DMARC record to the domain’s DNS. The DMARC record specifies the DMARC policy, DMARC data, and email addresses for sending DMARC reports for the domain. Once configured, DMARC will reveal any and all sources of email messages that are sent on behalf of a company or domain, allowing the organization to control and manage their email communication.

Conclusion
DMARC is a valuable tool for protecting email domains from fraudulent activity and increasing confidence in email communications. There are a significant number of threats that specifically target email users, and it is essential that domain owners take steps to protect their domains from fraudulent email activity. DMARC provides a mechanism that enables organizations to define policies to authenticate their email messages and protect against cyber attacks. Implementing DMARC can be a challenge, but this extra effort is worth it when considering the security and reputation benefits it offers.
