We are facing a global phenomenon: inflation. Companies everywhere are laying off employees, tightening budgets, and cutting costs. Now is the time to optimize your business operations and double down on security to protect against losses. We’ll tell you what you can do right now to improve your email performance and protect your business against email spoofing and impersonation attacks.
What Is Email Spoofing?
How to Strengthen Your Email Security Profile Through DNS
Sender Policy Framework or SPF combats sender address forgery by verifying the MAIL FROM during email transmission. SPF determines who and what can send mail on behalf of your email domain. Approved senders are specified in a TXT record in your DNS. If a sender is not in that list, SPF authentication will fail.
DomainKeys Identified Mail or DKIM authenticates the sending email domain. When an email is composed, a digital signature is created. If DKIM is enabled, the receiving mail server will verify if the email was signed by the sending email domain, meaning the message has not been modified during transit.
DMARC or Domain-based Message Authentication, Reporting and Conformance takes the results from SPF and DKIM to tell receiving mail servers how to treat emails that fail the DMARC validation. This is done by specifying a policy in your DNS: none, quarantine, or reject.
Why Is DMARC Essential?
Many companies are unaware of problems with their authentication practices. Unless messages bounce back to the sender, there is no way to determine how many legitimate messages are being sent that can’t be authenticated and delivered or even the scope of the fraudulent emails that make their way to the end user’s inbox.
The only way to address these issues is for senders and receivers to work together in sharing information about the email they send to each other. DMARC helps email senders and receivers determine whether or not a given message is legitimately from the sender, and what to do if it isn’t. This process improves email deliverability and protects users and brands from costly abuse.
