n8n Workflow: PCI DSS Control Evaluation and Compliance Tracking

This n8n workflow provides a robust framework for evaluating PCI DSS controls and tracking compliance. It's designed to process control data, apply conditional logic for assessment, and manage the flow of information for reporting or further action.

What it does

This workflow is a foundational structure for processing and evaluating data, likely related to compliance controls. It includes the following key steps:

1. Manual Trigger: The workflow is initiated manually, allowing for on-demand execution.
2. Google Sheets (Input): It is designed to read or write data from/to Google Sheets, likely serving as the source for PCI DSS control data or a destination for evaluation results.
3. Code (Data Transformation): A "Code" node is included, indicating custom JavaScript logic will be applied to transform or process the data. This is where specific evaluation rules for PCI DSS controls could be implemented.
4. If (Conditional Logic): An "If" node allows for branching logic based on conditions. This is crucial for evaluating whether a control meets specific criteria (e.g., "compliant," "non-compliant," "requires attention").
5. Edit Fields (Set): Two "Edit Fields (Set)" nodes are present, one on each branch of the "If" statement. These nodes are used to modify or set specific fields based on the outcome of the conditional logic (e.g., setting a "Compliance Status" field).
6. Merge (Combine Paths): A "Merge" node combines the data streams after the conditional processing, bringing the workflow back to a single path for subsequent actions.
7. Filter (Data Filtering): A "Filter" node is included, suggesting that further filtering of items based on specific conditions can be applied after the initial evaluation.
8. Sticky Note: A "Sticky Note" is present, likely containing important information or instructions for the workflow's usage or context.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance (self-hosted or cloud).
• Google Sheets Account: Configured Google Sheets credentials within n8n to interact with your spreadsheets.

Setup/Usage

1. Import the Workflow: Import the provided JSON into your n8n instance.
2. Configure Google Sheets:
   • Click on the "Google Sheets" node.
   • Select or create your Google Sheets credential.
   • Configure the spreadsheet ID and sheet name from which you want to read or write data.
3. Customize Code Node:
   • Open the "Code" node.
   • Implement your specific PCI DSS control evaluation logic using JavaScript. This is where you would define how control data is assessed.
4. Configure If Node:
   • Open the "If" node.
   • Define the conditions that will determine the branching logic based on your PCI DSS control evaluation (e.g., {{ $json.status === 'Compliant' }}).
5. Customize Edit Fields (Set) Nodes:
   • On each branch of the "If" node, configure the "Edit Fields (Set)" nodes to update relevant fields based on the evaluation outcome (e.g., setting a complianceStatus to "Compliant" or "Non-Compliant").
6. Configure Filter Node:
   • Open the "Filter" node.
   • Define any additional filtering conditions if you need to process only a subset of the evaluated controls.
7. Activate the Workflow: Once configured, activate the workflow.
8. Execute Manually: Click "Execute Workflow" in the "Manual Trigger" node to run the workflow on demand.

This workflow provides a flexible foundation. You can extend it by adding nodes to:

• Write evaluation results back to Google Sheets.
• Send notifications (e.g., Slack, Email) for non-compliant controls.
• Integrate with other GRC tools or databases.
