Over 34% of criteria require developer support,? the Payment Card Industry Data Security Standard (PCI DSS) 4.0, which spans over 356 pages, can be somewhat intimidating for the average software developer who is not yet proficient in the field of cybersecurity.

PCI DSS encompasses a variety of requirements for software developers, product managers, cybersecurity professionals, finance, and other support staff. Consequently, it may be regarded as a comprehensive company initiative.

This article is intended to facilitate the understanding of how to plan for software security decisions by mapping PCI DSS requirements to software development.

“ Please be advised that this article will not address the specific use cases that necessitate PCI SSC compliance if your organization is developing payment software or other related software.

While an organization must comply with all PCI DSS criteria, it is critical to have a developer's viewpoint on how these requirements should be reviewed early in the software development process. At a high level, here's a chart showing how I determine what is relevant by team:

Now If we go in details in each department or section in the development we find the following diagram:

As you can see most of the work relay in the backend developer, however 21% of the requirement is also shared across all department, table below list the above charts in numbers:

The last chart I want to show here the amount of work required between Technical,Procedures and Documentation:

As you can see in the chart above round 36.20% of the required action is under the development team , In next article will go in details for each requirement and how to build PCI-DSS application from ground-up.
