An information security analyst is working with a data owner to identify the appropriate controls to preserve the confidentiality of data within an enterprise environment.
One of the primary concerns is exfiltration of data by malicious insiders.
Which of the following controls is the MOST appropriate to mitigate risks?

A. B. C. D.D.
The most appropriate control to mitigate the risk of exfiltration of data by malicious insiders is data loss prevention (DLP).
DLP is a set of technologies and processes designed to detect and prevent the unauthorized transfer of sensitive information, such as intellectual property, financial data, and personally identifiable information. DLP solutions can be deployed on endpoints, servers, and network gateways to monitor data in transit, at rest, and in use.
DLP solutions use a combination of techniques such as content analysis, context awareness, and user behavior analytics to identify and prevent data exfiltration. Content analysis involves scanning the content of data for specific keywords, patterns, or regular expressions that indicate sensitive information. Context awareness involves analyzing the context in which the data is being used, such as the user's role, location, and device, to determine if the data transfer is legitimate or not. User behavior analytics involves monitoring the behavior of users over time to identify abnormal patterns of data access or transfer.
Data deduplication, OS fingerprinting, and digital watermarking are not appropriate controls to mitigate the risk of data exfiltration by malicious insiders.
Data deduplication is a data compression technique that eliminates duplicate copies of data to reduce storage space. It does not address the issue of data exfiltration.
OS fingerprinting is a technique used to identify the operating system of a remote host by analyzing its network traffic. It does not prevent data exfiltration.
Digital watermarking is a technique used to embed invisible codes or markers into digital content to identify its source or ownership. It does not prevent data exfiltration.
Therefore, the most appropriate control to mitigate the risk of exfiltration of data by malicious insiders is data loss prevention.
