DMARC Protects Your Domain Brand
Imagine this fraud scenario.
Your outside controller Connie, got an email from your staff person Stacy to disperse funds.
One of three things happened.
- Stacy sent it to Connie.
- Stacy’s PC apparently got a virus and sent the request to Connie.
- Stacy has been on vacation, her computer has been turned off. There is no way Stacy sent Connie the request. so… Either Connie or Stacy once got a virus that stole the address list linking Stacy and Connie. The virus is now gone, the knowledge remains. Thus, Stacy’s email address was spoofed from a criminal source.
The Dmarc process adds the following TXT records to your domain name to prevent spoofing. The setting tells receivers of emails with your domain name how to run a valid security check.
The TXT records to add are;
- SPF lists valid email senders by IP address such as the IP address of your email server or range of IP addresses of your mass email marketing service.
- DKIM is an email security setting much like a code word “so and so sent me and the code word is xxx”
- DMARC tells a receiver what to do if those authentication methods fail. Choices are
- None = do nothing but tell someone that it happened such as the DMARC report collection service we use
- Quarantine = send the email to a spam folder
- Reject = reject the email.
In short, DMARC protects your email brand. Take this test. You will find our record and that of many respected companies are “all green”
Many IT consultants don’t establish Dmarc records for themselves nor for their customers
First lookup at our fully secure and properly setup (aggressive setting of reject) Dmarc record. We use a popular industry tool not at all connected with our Infotel Systems.
infotelsystems.com gets all green check marks.
So do the “FANG” technology companies facebook.com, amazon.com, apple.com, netlfix.com, microsoft.com, google.com. So do the popular email domains yahoo.com and aol.com.
gmail.com and hotmail.com have not yet adopted.
