Introduction
We’ve all heard a lot about phishing and how attackers steal money and data from gullible users. The impact is huge. You might wonder. How do we get rid of this menace? How do we keep our emails safe? How do we ensure that our emails are used by just us and not somebody else?
We have an answer for all your questions: DMARC!
DMARC for Dummies
DMARC (Domain-Based Message Authentication, Reporting, and Conformance) is a standard or system for determining whether or not an email is legitimate. It uses SPF and DKIM, two additional protocols, to determine an email's authentication state. DMARC allows organizations to see who is sending emails from their domain, improves email delivery, and, most critically, protects against domain spoofing, phishing, and impersonation threats.
If your company's domain name is mycompanyisthebest.com, you don't want a cyber attacker to be able to send emails from that address. This jeopardizes your brand's reputation and has the ability to propagate financial malware. The DMARC standard avoids this by verifying that emails are being sent from the expected IP address or domain. It defines how domains should be informed if there are difficulties with authentication or migration, and it gives forensic information so that senders may monitor email traffic and quarantine suspicious emails.
Now you might ask why would you need DMARC specifically?
Why DMARC?
Well, firewalls and Internet security software, for example, are insufficient to guard against email phishing attacks. To strengthen your security, you must first understand how your firm communicates via email. This necessitates the use of advanced techniques, such as professional email forensics software. These programs can help you parse and analyze every email that your company sends and receives in order to identify potential email phishing attempts and mitigate damage even if an attack has already happened. However, before you do so, you should think about implementing easily available email security standards like DMARC, SPF, DKIM, and DMARC is the best option available to safeguard your incoming and outgoing emails.
Identifying a Phishing Attack
The threat of spoofing is not new. Email spoofing is a misleading technique used by attackers to modify both the identity of the sender and the seeming origin of email communication. The majority of spoofing attacks employ falsified header information or construct a bogus sender email address.
Recipients can detect phishing emails sent from a faked firm domain by inspecting the email header information, such as the “from:” and “return-path” addresses, and ensuring that they match. While the email “From” address is normally accessible in the header, the “return-path” address is not always visible, and upon inspection, it might assist receivers to determine the original identity of the attacker.
Stop Email Phishing Using DMARC
To let DMARC handle all security checks for your email communications, you need to set up the policy of p=reject. It is an effective solution in countering a wide range of assaults, such as direct-domain spoofing and email phishing.
DMARC assists in verifying the origin of emails and preventing bogus emails from being received and opened. However, only a tiny number of firms have embraced the protocol, and an even fewer number of them have done it successfully.
