Email is a fantastic way for companies to advertise their brand and gain customers. Email, on the other hand, aids the dissemination of spam, phishing, malware, viruses, and other forms of fraud because it is difficult to say whether the sender is who they claim to be.

A new email authentication standard was adopted by email senders and receivers to help email senders deliver valid emails to recipients while also blocking phishing and fraud messages.

What is DMARC?

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It is an email validation system designed to protect your company’s email domain from being used for email spoofing, phishing scams, and other cybercrimes. Its aim is to prevent email spoofing, phishing scams, and other malware from being sent from the company’s email domain.

SPF (Sender Policy Framework) and DKIM (DomainKeys Defined Mail) are two existing email authentication techniques that DMARC uses (Domain Keys Identified Mail). DMARC introduces a crucial feature: reporting. When a domain owner adds a DMARC record to their DNS record, they’ll be able to see who’s sending an email on their behalf. This data may be used to obtain more specific information about the email channel. 

A domain owner can gain control over emails sent on his behalf using this information. DMARC can be used to shield the domains from phishing and spoofing attacks.

Why Does Your Business Need DMARC?

There is no medium with a broader scope than email, which has nearly 5 billion accounts worldwide. As a result, cybercriminals choose this channel for their malicious purposes. Despite the fact that improved security measures have been implemented in recent years to secure this platform, crime continues to rise year after year. 95% of all cyber-attacks and data breaches involve emails.

DMARC adds value in this field. DMARC not only gives you complete visibility into your email channels but also renders phishing attacks noticeable. DMARC is more powerful: DMARC will reduce the impact of phishing and malware attacks, prevent spoofing, protect against brand misuse and scams, and protect business email from being compromised. DMARC Check enables organizations to deploy DMARC and simplify their DMARC setup.

Where Does DMARC Help?

Malicious emails sent on their behalf threaten organizations and their clients; DMARC will stop these attacks. A company may gain insights into their email channel using DMARC. Organizations will focus on deploying and executing a DMARC policy based on the information provided.

Organizations are shielded from the following threats when the DMARC policy is set to p=reject:

  • Phishing on customers of the organization
  • Brand abuse & scams
  • Malware and Ransomware attacks
  • Employees from spear phishing and CEOs from fraud

Organizations will gain complete insight into their email channel using ProDMARC. Since companies could historically only learn about phishing attacks after they had already occurred, DMARC’s ability to gain complete visibility into the email channel is a significant benefit. It is possible to gain insight into phishing attacks using DMARC. Customers will be told ahead of time in this manner, resulting in a more positive experience. This way, customers are aware of these attacks in advance.

DMARC in Practice

DMARC’s primary aim is to identify and avoid email spoofing. Phishing scams, for example, use bank domains to send emails on their behalf. Customers of that bank believe they have received a legitimate email informing them that their bank card is no longer valid. The connection you are supposed to click will take you to a fake website.  This website is exactly the same as the real website and logging in will provide cybercriminals the possibility of using your credentials.

Originally, email authentication strategies such as DKIM and SPF were used to secure the domains from such scams. Cybercriminals, on the other hand, can get around these safeguards. DMARC will establish a connection between SPF and DKIM in order to completely protect your domain and email channel. When you add DMARC to your DNS record, you gain control over your email channel. 

On a regular basis, ISPs can provide Aggregate (RUA) and Forensic (RUF) DMARC reports, which can be sent to the email address mentioned in your DMARC log. Aggregate Reports (RUA) and Forensic DMARC Reports (RUF) are the two forms of DMARC reports available:

Aggregate DMARC reports (RUA) are

  • Sent on a daily basis
  • Provide an overview of email traffic
  • Include all IP addresses that have attempted to transmit email to a receiver using your domain name

Forensic DMARC reports (RUF) are

  • Real-time
  • Only sent for failures
  • Include original message headers
  • May include the original message

SPF, DKIM, and DMARC outcomes can all be monitored and analyzed using ProDMARC’s dashboard. Adding a DMARC record to your DNS isn’t enough to keep your domains secure. DMARC works for three different DMARC rules, allowing you to choose what happens to your addresses. The ‘none’ policy is only used to gather data and keep track of your latest email channel. 

There are two more DMARC policies to enforce your email channel. The DMARC ‘quarantine‘ policy would send a malicious email to the recipient’s spam folder, while the ‘reject’ policy will not deliver the email at all.

Why is DMARC Important?

To tie all of these, DMARC provides the following benefits to domain owners:

Prevention of fraud emails

You can tell email receivers to reject any email that appears to come from your domain but fails the DMARC check if you use DMARC and ensure all of your valid email sources follow DMARC alignment. DMARC is an anti-phishing control that has been used to prevent massive quantities of email fraud.

Simplified delivery to the recipient’s Inbox

DMARC makes it easy for email recipients to recognize a letter. To combat spam, email recipients devote a significant amount of time, money, and resources to the development of technology that filters out unwanted messages. The DMARC implementation helps email receivers streamline their filtering rules, easily identify and distribute emails. If an email passes DMARC authentication, it means it truly comes from the domain displayed in the From address.

Protection of the domain and brand reputation

You can detect unauthorized senders using your domain by reviewing DMARC reports, and you can tell recipients to reject emails sent from your domain if they fail the DMARC search. This will reduce the number of unsolicited emails from your domain, which will damage your sender’s credibility, brand, and ROI.

Email traffic control

The use of DMARC gives you complete control over your email sources, ensuring that they only deliver valid messages to your subscribers. You can verify whether your valid sending sources pass the SPF and DKIM checks, and you can resolve any authentication problems that arise. 

DMARC allows businesses to monitor how their partners send emails on their behalf to ensure that everything is sent correctly. This lowers the chances of your sending IP/domain being blacklisted for sending spam emails.

Easier email visibility and brand recognition

You will use the BIMI standard to show your logo next to your messages in the recipient’s inbox if you use DMARC enforcement. BIMI assists the recipient in recognizing your emails in a crowded inbox and ensuring that the email was sent by you and not by anyone posing as you. 

The BIMI standard is currently only endorsed by Yahoo and Gmail’s mailbox provider.

For those concerned about email deliverability, DMARC has become a “must-have.” If your emails are not DMARC compliant, they can compete for a user’s Inbox with spam and fraud emails.

What Is DMARC And Why Does It Matter To You?

Question mark. 3d abstract on dark background with dots and stars. Ask symbol. Help support, faq problem symbol, think education concept, confusion search illustration or background.Business man.

DMARC is the acronym for Domain-Based Message Authentication, Reporting, and Conformance.

It is a security practice in the world of email that allows people to determine which messages are from legitimate sources such as businesses, and which are from fraudsters seeking to take advantage of them.

DMARC is used by organizations in a number of industries for a variety of purposes that we will address later, but the overarching aim is to defend against spam and reduce cybercrime.

The definition of DMARC is not entirely new. Instead, it employs DKIM and/or SPF to conduct a more detailed review of each email received.

A domain owner may define its own authentication protocol with DMARC using a DMARC policy

The DMARC policy is used to signal to an incoming server what to do if a message fails the DMARC test. Finally, the policy will produce reports that detail each review to help enhance processes and provide early warning if the account is spam.

Let us take a look at how the other two methods for authenticating emails operate to get a better understanding of this process.

How does DMARC work?

The best way to understand DMARC is that it is a method of evaluating whether or not an email is authentic. Companies may use this standard to publish policies or regulations within their email system, causing messages that do not follow particular criteria to be discarded.

Anyone studying DMARC should be familiar with the acronyms SPF and DKIM, which stand for Sender Policy Framework and DomainKeys Defined Mail, respectively. Before DMARC can be implemented, each of these protocols must be defined.

SPF

The Sender Policy Framework is a process that allows you to accept messages sent on your behalf. Each email contains a communication between the recipient’s DNS server and the sender’s DNS server.

By introducing an SPF, your DNS will only be able to send messages from IP addresses that have been authorized (essentially, devices).

Emails from other IP addresses are blocked, so no one in another country can send messages on your behalf.

There are many tools available to help you set up an SPF. Although each domain provider will typically have its own set of rules to follow, ProDMARC’s version of the DMARC setup process is relatively simple.

DKIM

DKIM, on the other hand, is relatively straightforward to describe but substantially more difficult to implement than SPF.

Each email will be marked with an invisible stamp that works similarly to a signature on a letter. This information is stored in the header and decrypted by the recipient’s server, which enables it to authorize the sender based on what it knows about them.

Many tech experts also note the use of DKIM to ensure that an email has not been tampered with on the way to the recipient’s inbox, similar to how people line out blank spaces on checks to prevent further information from being added.

DKIM is a little difficult to set up. It requires the development of a public key (the system that enables a mail server to decrypt your signature) as well as a private key (which encrypts it, therefore hiding it from others).

Your domain provider should have instructions that will allow you to set up both.

Why should your organization use DMARC?

By now, you should have a clear idea of why it is important to have DMARC records associated with your messages. To drive home the point, we will go over each gain one by one, beginning with security.

DMARC’s reporting function means that receivers activated by DMARC can tell you:

Email Spoofing

There are several types of fraud, and email is arguably one of the worst-affected fields.

According to the Herjavec Group, cybercrime would cost the world $6 trillion by 2021; although it is difficult to predict how much of that would come from spoofing techniques, a simple glance through your junk mail can reveal how many people are trying to cheat you for financial benefit.

Of course, it is less about data breaches and network infiltrations that drill holes in the networks and steal money in this case. DMARC is used to check the company’s own identity, stopping actual consumers from communicating with people posing as you.

Damage To Your Brand’s Reputation

If one of your customers gives money or information to an imposter, the outcome will almost always be a negative experience.

DMARC is an extra security mechanism intended to keep out criminals who are becoming more innovative in their tactics.

That said, you should possibly say goodbye to any large orders from customers who were caught in the crossfire. They will be unsure of which senders they can trust, and even the mention of your brand can conjure up unpleasant memories.

Awareness

Many small businesses are unaware of how vulnerable they are to cybercriminals.

It is the same if you are a regular person with a small savings account. You should not want someone to steal your prize money because the criminals have bigger fish to fry.

Email authentication

If you send email messages that you think could be spoofed, you can inform recipients that if the SPF/DKIM checks fail, they can reject or quarantine the post. Rejection or DMARC quarantine is useful if you want your recipients to be 100% positive that an email from one of your receiving domains really came from you. This will ensure that your domains and brand are still trusted.

Feedback and reporting

There are two types of DMARC reports. Aggregate reports show you the email message header data as well as the recorded information, such as the message disposition, which indicates what the recipient did with the messages.The harassment reports that go through the email server Feedback Loops are close to forensic reports. They are modified versions of email messages that failed SPF, DKIM, or both. These are useful for finding any snags that may occur during the DMARC implementation.

Final Thoughts- Why is DMARC important?

We hope we have clarified the benefits of adopting a DMARC policy clearly, but cybersecurity professionals are taking their time to spread the word.

Although 47 percent of government domains have adopted this feature ahead of time, research reveals that just 0.5 percent of the world’s top one million domains have done so, despite the fact that 76 percent of email clients support it.

Worse still, according to research 77 percent of domains with a DMARC policy may not be sufficiently covered due to DMARC configuration issues.

It is important to set things up with the aid of an expert if you want to defend your organization from cybercrime.

How can DMARC prevent the misuse of your domain?

Cloud storage background, remixed from public domain by Nasa

The ability to create fake emails has long been used by cybercriminals as a tool for the deployment of spam, phishing attacks, or malware, and has been so since email was invented. DMARC is an easy way to give an email recipient the opportunity to verify an email’s validity with additional security that makes it easier to recognize.

It is understood that cybercriminals copy well-known brands and use the trusted reputation of the brand to send emails to recipients and orchestrate an impostor. The offenders end up giving away confidential data such as credit card pins, passwords or even end up making payments to the impostors.

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email protection service that enables the identification and prevention of email spoofing. The aim of DMARC is to wage war on email phishing scams, where the address of the sender has been forged to look as if it came from a legitimate organization.

How does DMARC protect your domain emails?

For an organization that sends emails to its customers, DMARC guarantees that valid emails are authenticated and the identity of the sender is checked by the email service provider of the recipients. Fraudulent emails that tend to be originating from domains under the jurisdiction of the company are blocked. In its DMARC policy, the organization can also include domains that do not send emails or even defensively registered domains.

Inbound emails that fail DMARC authentication do not enter the inbox of the recipient, so phishing emails are filtered out. So, if you get an Income Tax Department email with a “From” address with intimations@cpc.gov.in, did cpc.gov.in really approve the message?

DMARC is built on two existing and widely deployed email authentication techniques, the Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM).

SPF- enables domain owners to approve hosts who can use the “MAIL FROM” or “HELLO” identifier with their domain name. A list of hosts that are permitted to use a specific domain name is published as a specially formatted TXT record in the Domain Name System (DNS) records of that domain.

DKIM– allows a digital signature for a domain owner tag and email message. Email authentication is performed using the public key of the signer, which is published in the DNS. A valid signature ensures that, since the signature was attached, at least some parts of the email have not been changed.

While SPF and DKIM helped identify fake emails, neither of these protocols included a way to report what and why messages were denied. DMARC addresses this issue by enabling domain owners to tag sent messages to prove validity with certain domain identifiers.

It provides instructions for receiving email servers on how to deal with messages that fail authentication tests for SPF and DKIM; and also provides a reporting system to convey what activities were taken under the policies.

Benefits of DMARC

What separates DMARC from other protocols for email authentication is its reporting feature. You can see who sends emails on behalf of your domain, your brand, with DMARC, and stop spammers from using it to send fake emails.

DMARC’s reporting function means that receivers activated by DMARC can tell you:

  • How many messages they’ve received using your domains in the From address
  • Where the messages come from
  • If they passed DKIM and SPF tests on these messages

Other advantages:

  • Before DMARC, receiving email servers did their best to decide whether or not the email was legitimate. It was never perfect and users had to search for lost emails in spam folders.
  • DMARC offers visibility dealing with messages that fail to authenticate.
  • By preventing unauthorized hosts from sending mail on your domain’s behalf, publishing a DMARC record protects your brand.
  • Valid emails are easily recognized after setting up your DMARC Record. This means you can advise all recipients to reject emails from anyone who imitates your business. This was DMARC’s original goal-to stop domain harassment.
  • DMARC reports give you an insight into who is sending mail from your domain.

It is easier to decide that the messages are not bad for inbox providers. Such emails are more likely to be sent easily and without errors to the recipient’s mail. Setting up a DMARC policy and finding the best service provider to deliver your emails would only help improve the credibility of your company.

Conclusion

We at ProGIST suggest getting a well-implemented DMARC setup to avoid emails reaching end-users who spoof your domain. This is a highly successful way to avoid the sending of both general phishing emails to your customers and spear phishing emails to your employees.
