Email is the most popular mode of communication in the digital age, but it’s also vulnerable to cyberattacks. Phishing and spoofing attacks are common, and they can cause significant harm to individuals and businesses alike. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps prevent such attacks by providing a way for email recipients to verify the authenticity of incoming emails. Deploy DMARC can seem like a complex task, but it doesn’t have to be. In this article, we’ll explore the easy way to deploy DMARC and secure your email domain.
What is DMARC?
DMARC is an email authentication protocol that uses Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to verify the authenticity of incoming emails. It enables email domain owners to publish policies for email authentication and provides a mechanism for email receivers to check those policies.
DMARC allows email receivers to determine if incoming emails are legitimate or not by checking the SPF and DKIM signatures. If the email fails these checks, the receiver can take appropriate action, such as quarantining or rejecting the email.
Why Deploy DMARC?
To Deploy DMARC can help you secure your email domain in several ways:
- Prevent Phishing and Spoofing Attacks: DMARC helps prevent phishing and spoofing attacks by enabling email receivers to verify the authenticity of incoming emails. If an email fails DMARC checks, it’s likely to be fraudulent, and the receiver can take appropriate action.
- Protect Your Brand Reputation: Phishing and spoofing attacks can damage your brand reputation. By deploying DMARC, you can protect your brand reputation by preventing fraudulent emails from being sent using your domain.
- Improve Email Deliverability: DMARC can also improve your email deliverability by reducing the likelihood of your emails being marked as spam or phishing emails. When email receivers see that you have deployed DMARC, they are more likely to trust your emails and deliver them to the inbox.
Steps to Deploy DMARC
To Deploy DMARC may seem like a daunting task, but it doesn’t have to be. Here’s the steps to deploy DMARC:
Step 1: Create DMARC Record
The first step in deploying DMARC is to create a DMARC record for your domain. A DMARC record is a DNS record that specifies your DMARC policy. Here’s an example DMARC record:
In this example, the DMARC policy is set to “reject,” which means that emails failing DMARC checks should be rejected. The “pct” parameter specifies the percentage of emails that should be subjected to DMARC checks, and the “rua” parameter specifies the email address to which DMARC reports should be sent.
Step 2: Publish DMARC Record
Once you’ve created your DMARC record, you need to publish it in your DNS. This involves adding a TXT record to your DNS with the following information:
_dmarc.yourdomain.com. IN TXT “v=DMARC1;p=reject;pct=100;rua=mailto:firstname.lastname@example.org”
Make sure to replace “yourdomain.com” with your actual domain name and “email@example.com” with your actual email address.
Step 3: Monitor DMARC Reports
After you’ve deployed DMARC, you should monitor DMARC reports to ensure that everything is working as expected. DMARC reports provide valuable information on the status of your email authentication and can help you identify and address any issues.
You can use SimpleDMARC reporting tools to generate and analyze DMARC reports of your domains. These tools provide detailed information on the status of your DMARC policy, including the percentage of emails that pass or fail DMARC checks, the sources of failed emails, and recommendations for improving your DMARC policy.
Step 4: Adjust DMARC Policy
Based on the DMARC reports, you may need to adjust your DMARC policy to improve your email authentication. For example, you may need to adjust your SPF or DKIM settings or increase the percentage of emails subjected to DMARC checks.
It’s essential to monitor and adjust your DMARC policy regularly to ensure that it remains effective in protecting your email domain.
