PCI DSS Network Segmentation: Explained.
Network segmentation is the practice of dividing a computer network...
The Purpose of Network Segmentation Penetration Testing for PCIDSS is to identify and validate effectiveness of network traffic restrictions between defined segments from out-of-scope networks to the in-scope networks that hold sensitive information such as Customer Card Holder Data (CHD) Cardholder Data Environment(CDE) is a network segment that stores, processes and transmits cardholder data.
Network segments help in avoiding congestion in the overall network and isolate crucial segments (those that have critical data) from other segments. Every organization follows their own segmentation process and procedures as per their business requirements. Segmentation Penetration Testing is carried out as a requirement of Industry-standard Compliances such as Payment Card Industry Data Security Standards (PCI-DSS).
As per PCI guidelines, Segmentation Penetration Testing is required to be done once every year for merchants and once every six months for merchant service providers.
