Business Email Compromise or BEC is a form of email security breach or impersonation attack that affects commercial, government, non-profit organizations, small businesses and startups as well as MNCs and enterprises to extract confidential data that can negatively influence the brand or organization. Spear phishing attacks, invoice scams and spoofing attacks are all examples of BEC.
Cybercriminals are expert schemers who intentionally target specific people within an organization, especially those in authoritarian positions like the CEO or someone similar, or even a trusted customer. The worldwide financial impact due to BEC is huge, especially in the US which has emerged as the prime hub. Read more about the global BEC scam volume. The solution? Switch to DMARC!
What is DMARC?
Domain-based Message Authentication, Reporting and Conformance (DMARC) is an industry-standard for email authentication. This authentication mechanism specifies to receiving servers how to respond to emails failing SPF and DKIM authentication checks. DMARC can minimize the chances of your brand falling prey BEC attacks by a substantial percentage, and help protect your brand’s reputation, confidential information and financial assets.
Note that before publishing a DMARC record, you need to implement SPF and DKIM for your domain since DMARC authentication makes use of these two standard authentication protocols for validating messages sent on behalf of your domain.
You can use our free SPF Record Generator and DKIM Record Generator to generate records to be published in your domain’s DNS.
How to Optimize Your DMARC Record to Protect Against BEC?
In order to protect your domain against Business Email Compromise, as well as enable an extensive reporting mechanism to monitor authentication results and gain complete visibility into your email ecosystem, we recommend you to publish the following DMARC record syntax in your domain’s DNS:
v=DMARC1; p=reject; rua=mailto:rua@example.com; ruf=mailto:ruf@examplel.com; fo=1;
Understanding the tags used while generating a DMARC Record:
You can generate your DMARC record with PowerDMARC’s free DMARC Record Generator wherein you can select the fields according to the level of enforcement you desire.
Note that only an enforcement policy of reject can minimize BEC, and protect your domain from spoofing and phishing attacks.
While DMARC can be an effective standard to protect your business against BEC, implementing DMARC correctly requires effort and resources.

How Does DMARC Protect Against BEC?
As soon as you set your DMARC policy to maximum enforcement (p=reject), DMARC protects your brand from email fraud by reducing the chance of impersonation attacks and domain abuse. All inbound messages are validated against SPF and DKIM email authentication checks to ensure that they arise from valid sources.
SPF is present in your DNS as a TXT record, displaying all the valid sources that are authorized to send emails from your domain. The receiver’s mail server validates the email against your SPF record to authenticate it. DKIM assigns a cryptographic signature, created using a private key, to validate emails in the receiving server, wherein the receiver can retrieve the public key from the sender’s DNS to authenticate the messages.
With your policy at reject, emails are not delivered to your recipient’s mailbox at all when the authentication checks fail, indicating that your brand is being impersonated. This ultimately keeps BEC like spoofing and phishing attacks at bay.
