To block users from sending emails containing information subject to the Payment Card Industry Data Security Standard (PCI DSS), you can create a Data Loss Prevention (DLP) policy in Microsoft Exchange Online. Here’s how:

Create a Custom DLP Policy:

Log in to the Microsoft Exchange Online admin center.

Navigate to Data loss prevention > Policy.

Create a new custom policy specifically for PCI DSS compliance.

Define Conditions:

In the policy settings, define conditions that identify sensitive data related to PCI DSS. For example:

Keywords: Include terms like “credit card,” “debit card,” or specific card number formats.

Regular Expressions (Regex): Craft expressions to match credit card patterns (e.g., \b\d{4}-\d{4}-\d{4}-\d{4}\b for Visa/Mastercard).

Sensitive Information Types: Use built-in or custom sensitive information types related to payment cards.

Choose Actions:

Specify the actions to take when sensitive data is detected in emails:

Block: Prevent the email from being sent.

Notify Sender: Inform the sender that sensitive data is not allowed via email.

Add Disclaimer/Watermark: Optionally add a disclaimer or watermark to the email.

Apply the Policy to Emails Only:

Ensure that the policy is configured to apply only to emails (not other communication channels).

Exclude internal communication if necessary.

Test and Monitor:

Enable the policy in test mode initially to validate its effectiveness.

Monitor logs and adjust the policy as needed.
