Discover easy steps to mask data in Xano with this guide. Safeguard crucial info painlessly while boosting app security.
Implementing data masking in Xano means making the most of Xano's API backend to keep critical data safe. First off, pinpoint what data actually needs masking. After that, use Xano’s custom functions and conditional logic to change the data before it reaches clients. This method ensures personal information stays hidden from unauthorized eyes, boosting data privacy and compliance. By following this guide, integrating data masking into your Xano system becomes second nature.
First things first, log in to your Xano account with your credentials. Once you're in, head over to the project where you want to set up data masking.
Click on the "Database" tab on the left sidebar to get to your data tables. Pick the table where you want to apply data masking.
Add a new field in the table for storing the masked version of the sensitive data. Just click the "Add Column" button and give it a name, like masked_data. Set the data type based on what you need.
Now, go to the "API" tab on the left sidebar to define or tweak existing API endpoints. Pick the endpoint where you'll add the data masking logic.
In the selected API endpoint, adjust the data fetch logic by adding a function to mask the sensitive data. You can use Xano's built-in functions or custom scripts to swap out the original data with masked values.
Example:
let originalData = API.SQL("SELECT sensitive_data FROM your_table WHERE id = ?", [id]);
let maskedData = maskFunction(originalData);
API.response(200, { "masked_data": maskedData });
In the script editor, define the masking function. For instance, if you're masking an email:
function maskEmail(email) {
let [user, domain] = email.split("@");
let maskedUser = user.substring(0, 2) + "***";
return maskedUser + "@" + domain;
}
Use this function to transform the sensitive data in your API response.
Make sure your API response includes the masked data field. Edit the response object in your API configuration:
API.response(200, { "masked_data": maskedData });
Deploy the changes and run some tests to make sure the data masking works correctly. Use sample data to check that the sensitive info is properly masked in the API responses.
By following these steps, you can effectively implement data masking in Xano to boost data security and privacy.
