Which of the following is NOT a level of data protection in Dynatrace?

Masking at compression is not recognized as a level of data protection in Dynatrace. In the context of data handling, levels of data protection are generally focused on ensuring the data's privacy and security throughout its lifecycle, including how it is captured, stored, and displayed.

Scrubbing at capture involves removing or anonymizing sensitive information at the point of data acquisition, which prevents any sensitive data from entering the system in the first place. Scrubbing prior to storage pertains to actions taken to cleanse or anonymize data before it is saved in a database, ensuring that only non-sensitive information is retained.

Masking on display refers to the process of obfuscating sensitive information when it is presented to users, ensuring that while under certain circumstances users can interact with the data, they do not see sensitive information that is not relevant to them.

In contrast, masking at compression does not correspond to a recognized practice in data protection levels; compression typically deals with optimizing data size rather than focusing on privacy and security aspects. This distinction clarifies why masking at compression does not fit the recognized framework for data protection in Dynatrace.
