What type of masking strategy involves replacing data on a system while it passes between the data and application layers?
A dynamic masking strategy involves replacing data on a system in real-time as it passes between the data and application layers. This method ensures that sensitive information is masked dynamically during the normal processing of data, thereby protecting production environments while still allowing applications to function without interruption.
A. Dynamic
Dynamic Data Masking (DDM) is a masking strategy that replaces or obfuscates data in real-time as it passes between the data and application layers. It does not alter the data at rest; instead, it modifies the data only when it is accessed by specific users or applications, ensuring that sensitive information remains hidden from unauthorized users. Why the other options are incorrect: B. Static → Static Data Masking (SDM) permanently replaces sensitive data at rest in a database, making it irreversible. C. Replication → Data replication refers to copying data from one system to another for redundancy, not masking. D. Duplication → Similar to replication, duplication means creating exact copies of data, but it does not involve masking.
