Where is a DLP Solution Installed for Data in Use Monitoring?

D.

To monitor data in use, the DLP solution's optimal location would be on the user's client or workstation, where the data would be used or processed, and where it would be most vulnerable to access or exposure.

The network perimeter is most appropriate for data in transit, and an application server would serve as middle stage between data at rest and data in use, but is a less correct answer than a user's client.

A database server would be an example of a location appropriate for monitoring data at rest.

A Data Loss Prevention (DLP) solution is a security technology that is used to monitor and control the movement of sensitive data across an organization's network. It is designed to prevent data leakage, whether it is intentional or accidental, by detecting and blocking the unauthorized transmission of confidential information.

When it comes to monitoring data in use, a DLP solution is typically installed on the user's client, which is the endpoint device that the user interacts with. This is because data in use refers to data that is currently being accessed, processed, or modified by an authorized user on their device. Therefore, a DLP solution installed on the user's client can monitor and control the user's actions in real-time to prevent unauthorized access to sensitive data.

Installing a DLP solution on the application server, database server, or network perimeter would not be effective in monitoring data in use since it would only be able to monitor data at rest or in transit. Data at rest refers to data that is stored on a device or server, while data in transit refers to data that is being transmitted between devices or servers.

In conclusion, the correct answer to the question is D. User's client, as this is where a DLP solution is generally installed when utilized for monitoring data in use.
