PCI DSS scope refers to the systems, networks, people, and processes that must comply with Payment Card Industry Data Security Standard (PCI DSS) requirements because they store, process, or transmit cardholder data, or impact the security of the cardholder data environment (CDE).
Determining scope involves identifying all system components connected to or affecting the CDE including:
- Servers
- Applications
- Databases
- Network devices
- Personnel with access
Organizations conduct scoping exercises to define boundaries, implement network segmentation, and document which assets fall within compliance requirements. Accurate scoping is critical for efficient audits, appropriate resource allocation, and ensuring security controls are applied where needed while avoiding unnecessary compliance burden on systems that don’t handle payment data.
