With static masking, a separate and distinct copy of the data set is created with masking in place. This is typically done through a script or other process that takes a standard data set, processes it to mask the appropriate and predefined fields, and then outputs the data set as a new one with the completed masking done.

An injection attack is where a malicious actor sends commands or other arbitrary data through input and data fields with the intent of having the application or system execute the code as part of its normal processing and queries. This can trick an application into exposing data that is not intended or authorized to be exposed, or it can potentially allow an attacker to gain insight into configurations or security controls. Missing function-level access control exists where an application only checks for authorization during the initial login process and does not further validate with each function call. Cross-site request forgery occurs when an attack forces an authenticated user to send forged requests to an application running under their own access and credentials.
Cross-site scripting occurs when an attacker is able to send untrusted data to a user's browser without going through validation processes.

Data that falls under the purview of an eDiscovery request is that which is in the possession, custody, or control of the organization. Although this is an easy concept in a traditional data center, it can be difficult to distinguish who actually possesses and controls the data in a cloud environment due to multitenancy and resource pooling. Although these options provide similar- sounding terms, they are ultimately incorrect.
