To hide sensitive data exchanged between API consumers and API implementations while allowing the conversion of tokenized fields back to their original values for other API requests or responses, the best approach is to use tokenization. This involves:

Tokenization Format: Create a tokenization format that will be used to apply a tokenization policy in the API gateway. This format ensures that sensitive fields in message payloads are replaced with tokenized values that maintain a similar format, making them less recognizable as sensitive data.

Tokenization Policy: Apply a tokenization policy in the API gateway that replaces sensitive data with tokenized values.

Detokenization Policy: Apply a corresponding detokenization policy in the API gateway to convert tokenized values back to their original values when required by other APIs.

This method does not require recoding the API implementations and ensures that sensitive data is protected while still being accessible in its original form when necessary.

API Gateway Security Best Practices

To achieve efficient caching and reduce redundant database transactions, the following strategy can be implemented:

On Table Row Listener: Implement an "On Table Row" trigger on the employees' table. This trigger will monitor changes (inserts, updates, deletes) in the employee records.

Invalidate Cache: Upon detecting changes in the employees' table, the trigger will call a flow to invalidate the current cache.

Object Store for Caching: Utilize MuleSoft's object store to cache the employee data. This store can hold the data for quick retrieval.

Set Expiration Interval: Configure the expiration interval for the cached data to ensure it is cleared when necessary. For this scenario, since we are invalidating cache on actual data changes, setting the expiration interval to empty can be suitable.

Return Cached Data: If there are no updates, the cached response is returned, reducing database load.

Caching Strategies

Requirement Analysis: Jenkins files and folders used for CI/CD configurations are not part of the actual Mule package and should be excluded from the deployed archive.

Solution: MuleSoft provides the .muleignore file to specify files and directories that should be excluded from the packaged application.

Implementation Steps:

Create a .muleignore File: In the root directory of your Mule project, create a file named .muleignore.

Specify Exclusions: Add the paths of the Jenkins files and folders that you want to exclude from the deployment package into the .muleignore file.

# .muleignore example /path/to/jenkins/file1 /path/to/jenkins/folder/*

Build and Deploy: When you build your Mule application, the Mule runtime will read the .muleignore file and exclude the specified files and directories from the deployment archive.

Advantages:

Clean Deployment: Ensures that only necessary files are included in the deployment package, reducing the package size and preventing potential issues related to unwanted files.

Ease of Maintenance: Easy to update and manage which files are excluded from the deployment package.
