12 Core Security Requirements - Covers areas such as firewalls, encryption, access control, and vulnerability management.
Secure Network & Systems - Requires organizations to install firewalls and update security configurations.
Data Encryption & Masking - Mandates strong encryption for stored and transmitted payment data.
