The Payment Card Industry Data Security Standard (PCI DSS) is undergoing a major update that will take effect in March 2025. Organizations will need to enforce Domain-based Message Authentication, Reporting, and Conformance (DMARC) to comply with the new standards.
Just a quick reminder on some of the terms used:
What is DMARC?
What is BIMI?
What is SPF?
What is DKIM?
This update is designed to enhance email security by reducing the risk of phishing attacks and other forms of email fraud, thereby safeguarding cardholder information. Although the advantages of DMARC enforcement are evident, achieving compliance may prove difficult, especially for organizations with intricate email systems.
In this blog, we will discuss the forthcoming changes, their potential effects on businesses, and how KiZAN and Valimail can assist your organization in adapting to these updates smoothly.
What’s Changing in PCI DSS?
DMARC is an essential tool for email authentication that checks if messages comply with the policies set by the sending domain. The recent update to PCI DSS mandates that organizations implement DMARC policies, which means that any unauthenticated emails must be either quarantined or rejected by the recipient's server.
Key compliance highlights include:
- Enforcement Required: Organizations must set their DMARC policies to "p=quarantine" or "p=reject" by March 2025.
- Reporting Integration: PCI DSS now expects organizations to analyze DMARC reports as part of their security monitoring.
- Alignment with SPF and DKIM: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) must also be properly configured to ensure DMARC authentication succeeds.
For businesses unprepared for this transition, failure to implement DMARC enforcement could result in non-compliance penalties and increased susceptibility to cyber threats.
The High Stakes of Email Security
Phishing attacks remain a leading cause of data breaches, and the financial repercussions can be staggering:
- The Average Cost of a Data Breach: According to IBM’s Cost of a Data Breach Report 2024, the global average cost of a data breach is $4.45 million, with email-based attacks contributing significantly to these figures.
- Phishing Email Prevalence: An estimated 3.4 billion phishing emails are sent daily, targeting businesses and individuals alike.
- Click-Through Rates: Despite awareness efforts, phishing emails have an alarming average click-through rate of 3.4%, meaning millions of users inadvertently engage with malicious content daily.
Given the scale and impact of email-based threats, PCI’s push for DMARC enforcement represents a critical step in safeguarding businesses and consumers.
Challenges in DMARC Adoption
Despite its importance, implementing DMARC enforcement is no small feat. Organizations face several hurdles:
- Email Ecosystem Complexity: Managing multiple domains and third-party senders can complicate DMARC deployment.
- Misaligned Policies: Improperly configured policies can lead to legitimate emails being blocked, disrupting operations.
- Monitoring Overload: Interpreting DMARC reports requires expertise to identify issues and maintain compliance effectively.
Without the right tools and expertise, achieving PCI compliance can become an overwhelming endeavor.
