March 2025 is fast approaching, and IT leaders are under pressure to address the sweeping changes introduced by PCI DSS 4.0. Here are the top three things you need to know to stay ahead:
#1. Compliance Goes Beyond Email
Protecting sensitive cardholder data now means securing all communication tools – like Slack, Teams, and Zoom. Having sophisticated security controls are essential to safeguard every way your organization collaborates.
#2. Prepare for Technical Complexities
With over 50 new requirements becoming mandatory, you need to rapidly transform your traditional security controls into comprehensive real-time monitoring systems.
This includes key updates such as implementing DMARC, or Domain-based Message Authentication, Reporting, and Conformance, alongside complementary measures such as Sender Policy Frameworks and Domain Key Identified Mail for stronger email authentication.
Also, you will need to deploy anti-malware and URL protection to block phishing and malware threats.
In addition to that, you are going to need to strengthen encryption and network security, and retention policies for email and archives.
#3. Focus on Human Risk and Awareness
PCI now mandates phishing awareness as part of security training. You should consider taking a smarter, adaptive approach by delivering situational, real-time interventions to better protect your workforce.
