The Importance of Documentation in PCI DSS
2 min
Why Is Documentation So Important in PCI DSS?
You need to be as good with documentation as you are with the technical and physical aspects. In fact, the documents should be the blueprint of your technology and environment. More than 45% of PCI DSS requirements demand that you fulfill documentation requirements in the form of written policies, diagrams, guidelines, or checklists.
Documentation as the Foundation of Compliance
Producing a document that defines and explains your company and business is one of the most important parts of the PCI DSS compliance process. The document has to match the actual environment configuration and your work practices, which is a challenge. If there is a mismatch during the audit process, it becomes a major issue.
Therefore, it is wise to start with documentation at the same time as you begin setting up your environment for PCI DSS—ideally even beforehand.
Documentation Must Be Followed
However, documentation is not just about writing policies, procedures, roles, and processes—you actually have to follow them.
Policies and procedures are very specific to each company and should be driven and enforced by the personnel who work with them daily.
If you receive help from a third party, they need to work very closely with your company to produce accurate documentation. It is also important to ensure that the documentation matches your environment and working style.
Documentation in the Audit Process
Policies and procedures are among the most important elements during an audit and are often the most time-consuming. They serve as hard evidence that your framework meets the required standards.
Keep Documentation Clear and Continuously Improved
Policies and procedures should be straightforward and easy to understand. At the same time, confusion and different interpretations will always occur. Continuous improvement is necessary, and completely normal.
Guidelines for Policies and Procedures
Some guidelines to keep in mind:
- Try to cover as many areas of your company as possible
- Define policies, processes, and working methods in depth
- Clearly define and explain how they are implemented
- Explain your working standards and support them with reliable resources and knowledge
- Be open-minded and clear with your business justifications, especially for a QSA
- Break down policies into smaller, topic-specific documents to avoid constant updates to large documents
- Define roles and clearly assign responsibilities
From Documentation to Practice
Having a well-designed and clearly defined policy and procedure document is good, but not enough. You must enforce these policies and procedures as part of your daily routine. This is what audits are designed to verify: that your organization performs not only on paper, but also in real-world operations.
