It's no surprise that many businesses are looking to adopt DMARC authentication to check emails sent on their behalf, given the fast growth of email fraud and the fact that domain spoofing assaults account for a major part of these attacks.

Many firms have not yet implemented DMARC since it is difficult to establish and there is a large danger of DMARC difficulties, such as blocking the genuine email.

To further assist businesses and government organizations in protecting their trusted domains, we've identified five frequent DMARC authentication problems.

5 Common Mistakes Made While Implementing DMARC Many senders send emails on behalf of other companies, including third parties.

It might be difficult to identify all of the genuine senders, especially when different departments within a firm, such as marketing, sales, and human resources, employ third-party email senders.

Essential communications may be prohibited, creating business interruption if all valid senders are not discovered and authorized to send an email on behalf of the firm.

Email spoofing is the act of sending emails with a forged sender address.

It tricks the recipient into thinking that someone they know or trust sent them the email.

Usually, it’s a tool of a phishing attack, designed to take over your online accounts, send malware, or steal funds.

Reasons for email spoofing The reasons for email spoofing are quite straightforward.

Many companies and individuals use email spoofing or a phishing scheme in order to steal personal data, credit card information, and anything else related to online financial transactions.Email spoofing provides a multitude of motives.

Spoofing is not a new hacking technique, but it’s been used more frequently in recent years to trick people into giving up passwords and sensitive data.

DMARC is an email authentication standard that can help businesses fight the rising threat of brand exploitation, including email phishing attempts and business email compromise attacks. But it’s a complex protocol, the benefits and mechanisms of which are not often well-understood by non-security professionals. Blocking unauthenticated email is only the beginning; DMARC was designed as a framework for building policies and reporting on communications practices. In simple terms, DMARC analyzes SPF and DKIM results to instruct an inbound mail server what to do with messages that fail these checks. To use a real-world analogy, imagine an email is a package that needs to be delivered to a recipient at an office park. DMARC provides a means for companies to specify the actions associated with failed validation checks.

Let's look at how these two procedures vary from one another.DKIMDKIM (DomainKeys Identified Mail) is an anti-tampering technology that protects the security of your email while in transit.

Digital signatures are used by DKIM to verify that an email was sent from a certain domain.

SPF detects fraudulent sender addresses when the email is being sent.

Falsified sender claims are detected in the email's envelope, which is used when it bounces.

To identify email spoofing, common phishing, and spam tactic, SPF must be used in conjunction with DMARC.DKIM and why it’s better than SPF alone for Office 365DKIM encrypts a signature within the email header, whereas SPF adds information to the email envelope.

DomainKeys Identified Mail (DKIM) is an anti-tamper protocol that ensures your mail remains secure in transit. DKIM uses digital signatures to check whether the email was sent by the domain it claims to be from. DKIM uses two actions to validate your messages. The public key, however, is added to the DNS records of the user’s domain to help verify email messages. Take for example a receiving system that maintains a whitelist of secure sending domains that can be kept locally or obtained from third-party certifiers. In this case, DKIM can skip the filtering of signed emails from those whitelisted domains and filter the remaining emails more aggressively.

Email remains one of the most likely targets of cyberattacks simply because it’s comparatively easier to exploit than other systems. To point MSPs in the right direction, this guide will consider and explain a key aspect of robust email security, called Domain-based Message Authentication Reporting and Conformance (DMARC) email security. DMARC builds on existing technologies, such as Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM), to help prevent phishing and other malicious email spoofing. What makes DMARC unique is that it doesn't just tell receivers whether an email is spoofed or not, but it tells them who to contact if they have any issues or questions about the message they've received. A Domain-based Message Authentication, Reporting & Conformance (DMARC) protocol is an email validation system developed by internet engineers to combat phishing attacks. By adopting a new protocol called Domain-based Message Authentication, Reporting & Conformance (DMARC), companies are able to take action against these attacks and prevent data leakage that leads to major financial losses.

DomainKeys Identified Mail (DKIM) is an anti-tamper protocol that ensures your mail remains secure in transit. DKIM uses digital signatures to check that a specific domain sent an email. Emails signed with DKIM can be considered legitimate, and the recipients can rest assured that the email is not a spam or phishing attack. This signature may be verified using a public cryptographic key stored in the organization's DNS records. In the DKIM procedure, a public key is created as a TXT record for the domain's DNS Manager (registrar of the domain or DNS Provider). Every email sent has its own signature, which is produced with the domain's private key.

The public key is added to the DNS records of your domain to broadcast to the world and help verify emails.

In simpler words, a public key is issued as a TXT record for the domain's DNS manager in the DKIM process (registrar of the domain or DNS Provider).Every outgoing email has its own signature, which is generated using the domain's private key.

This private-public key combination is used by the recipient email server to verify all email sources.

When an inbound mail server gets an email, it looks up the DNS records to find the sender's public DKIM key.

To protect your brand from phishing, it is advised that you implement protocols such as DKIM, which help in verifying the legitimacy of the sender and establish trust. It uses digital signatures to confirm whether the email was sent by an authentic sender. DKIM authentication can be summarized in two simple actions. The first DKIM action occurs on the sending server that sends a DKIM signed email while the second takes place on the recipient server that affirms whether incoming emails have a DKIM signature. It consists of an encrypted header that is added to emails sent from domains that have DKIM implemented. The public key, however, is added to the DNS record of your domain to help verify your emails.

It can waste time, and it can sometimes be a bit of a gamble.Are you willing to gamble your system’s security?The good news is that you now have options for improved authentication protocols to adopt that can go a long way in protecting you from malicious emails spam.

Whenever you send an email, it includes additional text that is not always visible (depending on your email settings) that contains “return address” information for that email with details concerning the IP addresses and servers used to send the email.

If all looks good, then SPF authentication is approved and the message is delivered.Using DomainKeys Identified Mail (DKIM)DKIM adds a domain name identifier to the email that’s unique and separate from any other identifier.

You can easily adopt DKIM by adding a single DNS record and signing your existing emails with your own private key.

This signature allows the receiver of the message to verify the identity of the sender and detect any changes made to either the message or header information.

A new generation of email security has emerged in the last few years with the ability to provide greater assurances for recipients that their email is arriving intact, and that it’s actually coming from the stated sender. Whether you’re managing large organization with thousands of domains or an individual with a few websites, DKIM and SPF are critical to any email security program. DKIM helps to protect your domain by validating the From email address against the actual sending IP of the message, ensuring that your mail is legitimate. It prevents outsiders from sending out emails with forged sender information. If you’ve got top-notch sending practices such as high engagement, low spam, and minimal bounces, you’ll get a higher score, which improves your trust and reputation with ISPs.
