Change Detection Tools
Change detection tools monitor critical files on your systems and alert you when they're modified. PCI DSS requires file-integrity monitoring software to detect unauthorized changes to important system files.
Why you need it
These tools act as an early warning system, instantly notifying you if someone tampers with critical files that could compromise your payment card security.
What you need to do
If you already have change detection:
- Ensure alerts are sent to your admin users
- Confirm your team knows how to respond to alerts appropriately
If you don't have change detection:
Contact your IT support team or consult a qualified vendor to implement a file-integrity monitoring system
Bottom line
Without change detection, unauthorized modifications to your systems could go unnoticed, potentially compromising cardholder data and your PCI compliance.
