How ADP and Facebook battle bad e-mail

ADP and Facebook use DMARC seen by both as a way to fight phishing attacks

Each day cyber-criminals around the world manage to unleash untold millions of spoofed e-mails that fake well-known brand names to try and fool victims that receive this fraudulent e-mail into opening malware attachments or visiting malware-laden websites. To fight this scourge, security managers at companies like Automatic Data Processing (ADP), and Facebook that want to protect e-mail users and their brand name ramp up defenses against phishing.

Of growing importance in the phishing battle is participating in the growing global cooperative effort known as DMARC, which started just over a year ago. DMARC stands for "Domain-based Message Authentication, Reporting and Conformance," and it involves adjusting e-mail servers to publish DNS mail records using supported standards that include Sender Policy Framework (SPF) and DomainKeys Identified Mail.

"We're a massive target for the fraudsters," explains V. Jay LaRosa, senior director in ADP's global security organization in the division called the chief security officer's converged security architecture group. ADP's business services include payroll processing, and fraudsters target many an unwary victim by sending out deceptive e-mail that appears to concern ADP accounting.

"DMARC is critical to us," says LaRosa, saying ADP is DMARC-enabling its e-mail infrastructure so that fake ADP e-mail can be filtered out across the world because it is blocked by the growing number of service providers supporting the DMARC process. Today, it's estimated that 60% of the world's e-mail boxes are protected under the DMARC process, which means fake e-mail can potentially be blocked and filtered out before it hits the mailbox of any intended victim.

With assistance from partners such as Agari which aggregates e-mail phishing reports that are made available through the DMARC process, ADP can discover how widespread abuse of its corporate brand name is in terms of phishing.

ADP is still implementing the e-mail server changes needed to implement DMARC to protect e-mail users, and "We've seen a dramatic decrease in the impact of phishing," says LaRosa. But while things are proceeding well, one main question that remains is how to bring the DMARC protection system to include outside services such as Salesforce.

Facebook also says DMARC is an important weapon in that fight.
