powertools-lambda-java
Powertools is a developer toolkit to implement Serverless best practices and increase developer velocity.
AWS Lambda Powertools Data Masking AWS Lambda Powertools is “a developer toolkit to implement Serverless best practices and increase developer velocity” originally developed in Python but made available for Java, Typescript and .NET. As of now only the Python version offers a utility for data masking. Two approaches are proposed. One approach which uses a KMS key to encrypt/decrypt the sensitive information inside the log. A second approach which simply erases the sensitive information before writing the logs. To implement the first approach but also comply with regulations like the right to be forgotten, you would need to have one encryption key per customer, find some way to encrypt each customer’s information with their own key. Should they exercise their right to be forgotten, simply delete the encryption key, making their data forever unrecoverable. Although those approaches can address both problems, you must know exactly what to encrypt/erase. For example, to erase the phone number in a list of customers you would need to do something like this:
