This presentation explores how payment enterprises can design and implement a robust PCI DSS–compliant security baseline in cloud-native environments. It breaks down PCI DSS requirements into practical security domains, including network isolation, data protection, identity and access management, vulnerability management, logging, and continuous monitoring. Using real-world payment scenarios and cloud services as examples, the session demonstrates how to translate compliance controls into scalable security architecture. The goal is not only to pass audits, but to establish a sustainable security foundation that supports business growth, regulatory alignment, and long-term risk reduction for modern payment systems.
