Why Should Everybody Use DMARC To Prevent Phishing?

Phishing and malware attacks are often carried out via email. According to a May 2016 cyber threat report by an Internet security technology company, the Locky ransomware was solely responsible for a 412 percent rise in malware emails in March compared to February. Although knowledge and preparation are the most universally successful countermeasures, according to a recent report from a popular technology website, even that is extremely difficult. 

A combination of training and technical developments is most likely needed. One of the above concerns the validity of emails. Can you depend on the sender’s address in an email? In most cases, no, but DMARC allows you to do so.

To begin, an email has two sender addresses: 

  1. One is the “envelope” address, which is used as the return address if the email is not sent. The MAIL FROM SMTP comma is used to communicate between MTAs. The “envelope” address, which is used as a return address in the event that the email is not sent. The MAIL FROM SMTP command is used to communicate between MTAs.
  1. The email address that you see in your email app is the address written in the letter itself. It’s communicated in the form of a “From” header.

What is DMARC?

DMARC (Domain-based Message Authentication Reporting and Conformance) is a free and open technical specification that aligns SPF and DKIM frameworks to authenticate an email. Domain owners, large and small, can combat business email compromise, phishing and spoofing by implementing DMARC. 

With DMARC you can tell the world how to handle the unauthorized use of your email domains by instituting a policy in your DMARC record. 

DMARC Policies

The three DMARC policies are:

p=none

It keeps track of your email traffic. There will be no further action taken.

p=quarantine

Unauthorized emails are routed to the spam folder.

p=reject

The final strategy and the ultimate aim of DMARC implementation. This policy prohibits unauthorized email from ever being delivered.

Why Use DMARC for Email?

Email is involved in more than 90% of all network attacks, and without DMARC, deciding whether an email is real or false can be difficult. By combating phishing, spoofing, CEO fraud, and Business Email Compromise, DMARC helps domain owners protect their domain(s) from unauthorized use.

The operator of an Internet domain will tell the world that “anything I send is easy to recognize using DMARC—feel free to drop fake email that pretends to be me” by always sending DMARC compliant email.

Instead of attempting to screen out malicious emails, why not provide operators with a way to quickly recognize legitimate emails? This is where DMARC shines as an anti-spoofing technology. The promise of DMARC is that it will replace the inherently flawed “filter out evil” email protection model with one that “filters in good.”

Benefits of DMARC

To ensure that your customers can trust your emails

Essentially, you want everyone on the internet to be able to trust your email messages without having to worry about cybercrime or the problems that cyber-attacks might create for your business. To trick their victims into giving up details, cybercriminals are increasingly using well-known brands to send out email blasts with their logo. This is something that a DMARC check can help you stop.

To protect your brand

Another reason to use DMARC is to safeguard your carefully cultivated brand image from irreversible damage. When it comes to building and retaining a strong brand, nothing is more important than confidence, so imagine cybercriminals impersonating you. Email reports would list you as the sender, and the receiver may not be aware that the message is not genuine. DMARC aids in the prevention of spam.

To prevent C-level fraud

Finally, DMARC email provides security against C-Level attacks. These are commonly referred to as ‘Whaling’ and are carried out for the purpose of gaining authority and access within a corporation. Since they are identical in nature, whaling attacks are often confused with phishing attacks. You can use DMARC to influence the deliverability of Whaling attacks and thus add “trust” to your domain.
