Prioritised approach to PCI DSS

The Prioritised Approach to PCI DSS defines 6 key milestones which aid Merchants and other organisations to achieve overall compliance. It deploys a pragmatic approach towards compliance, addressing the more critical aspects early on within the compliance journey.

1. Remove sensitive authentication data and limit data retention.
   This milestone targets a key area of risk for entities that have been compromised. Remember – if sensitive authentication data and other cardholder data are not stored, the effects of a compromise will be greatly reduced. If you don't need it, don't store it.

2. Protect the perimeter, internal, and wireless networks.
   This milestone targets controls for points of access to most compromises – the network or a wireless access point.

3. Secure payment card applications.
   This milestone targets controls for applications, application processes, and application servers. Weaknesses in these areas offer easy prey for compromising systems and obtaining access to cardholder data.

4. Monitor and control access to your systems.
   Controls for this milestone allow you to detect the who, what, when, and how concerning who is accessing your network and cardholder data environment.

5. Protect stored cardholder data.
   For those organizations that have analyzed their business processes and determined that they must store Primary Account Numbers, Milestone Five targets key protections mechanisms for that stored data.

6. Finalize remaining compliance efforts, and ensure all controls are in place.
   The intent of Milestone Six is to complete PCI DSS requirements and finalize all remaining related policies, procedures, and processes needed to protect the cardholder data environment.
