To monitor data in transit, a DLP solution would optimally be installed at the network perimeter, to ensure that data leaving the network through various protocols conforms to security controls and policies.
An application server or a web server would be more appropriate for monitoring data in use, and 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 tool that aims to identify and prevent sensitive data from being accessed or transmitted outside of authorized channels. When it comes to monitoring data in transit, DLP solutions are typically installed at the network perimeter.
The network perimeter refers to the boundary between an organization's internal network and the external world, including the internet. This is where data enters and leaves an organization's network, making it the ideal location for monitoring data in transit.
At the network perimeter, DLP solutions can inspect all traffic passing in and out of the network, looking for sensitive data that matches predefined policies or rules. This allows organizations to prevent sensitive data from being transmitted over unsecured channels, such as email, instant messaging, or file transfer protocols.
It's worth noting that DLP solutions can also be installed on other types of servers, such as database, application, or web servers, depending on the specific use case. For example, if an organization wants to monitor sensitive data stored in a database, a DLP solution may be installed on the database server to inspect queries and data transfers. However, in the context of monitoring data in transit, the network perimeter is the most common installation location for DLP solutions.
