DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol. Its purpose is to enable email domain owners to prevent illegal usage of their domain (spoofing). That completely alters the dynamic of email security. Nonetheless, despite its importance, many businesses continue to use DMARC ineffectively.
In this blog post, we will be discussing the top 5 DMARC deployment mistakes that organizations should avoid.
Failing to publish DMARC records.
One of the most common mistakes organizations make while deploying DMARC is failing to publish DMARC records.
The DNS publishes DMARC records (Domain Name System). These outline the rules for email authentication that the domain’s owner intends to impose.
Not only are the advantages of DMARC lost to organizations who don’t publish DMARC entries. Yet, they also run the danger of phishing attempts being carried out on their domain.
Setting DMARC Policy to “None”.
Setting the DMARC policy to “None” while deploying DMARC for the first time is another error that enterprises frequently commit. Under the “None” policy, only reports are created; no emails are rejected or placed in quarantine. Although it can seem like a nice place to start, this is not advised. Because you are enabling phishing emails to be sent to your users by changing the policy to “None,” this is necessary. Your company will be put in danger as a result.
Organizations ought to begin with a “quarantine” policy instead. gradually transition to a “reject” stance as they gain confidence in DMARC.
Not monitoring DMARC reports.
The DMARC deployment procedure includes DMARC reports as a critical component. These reports include specific details about the emails being transmitted from your domain, such as which ones are successful and which ones are unsuccessful in the DMARC authentication process. Businesses who ignore these reports are losing out on important information regarding the state of their email security.
Moreover, they are neglecting to address any potential problems as they develop. Businesses must make sure they have a procedure in place for tracking DMARC reports and responding to any concerns that may occur.
Not configuring SPF and DKIM.
SPF (Sender Policy Framework) and DKIM (Domain-Keys Identified Mail), two more email authentication methods, are used by DMARC to verify the authenticity of emails. Companies who don’t have SPF and DKIM enabled miss out on DMARC’s advantages and run the risk of having their domain exploited in phishing attempts.
Before using DMARC, organizations should make sure that SPF and DKIM are implemented and that their records are current.
Not Keeping DMARC Records Up-to-Date.
Organizations should refrain from making the error of not maintaining their DMARC data. To reflect the change in your email ecosystem, such as adjustments to your email infrastructure or the inclusion of new email sources, DMARC records should be updated on a regular basis.
Businesses who don’t keep their DMARC records up-to-date risk having their domain exploited in phishing attempts and lose out on the advantages of DMARC.
DMARC is a crucial technology that businesses may use to safeguard their domains against phishing scams and email fraud. Organizations should be aware of frequent DMARC deployment problems, such as neglecting to publish DMARC records, setting the DMARC policy to “None,” failing to monitor DMARC reports, failing to configure SPF and DKIM, and failing to maintain DMARC records up-to-date. Organizations can assure by staying away from these errors.
