As more businesses begin to use encryption tech- nology, the security of data has enhanced tremendously over the years. However, it has also made it difficult to prevent data exfiltration. Conventional data loss prevention (DLP) tools often fail to scan encryption traffic, which makes them worse against advanced attacks. A different take on DLP architecture involves endpoint-based monitoring of data just before it gets encrypted. The different endpoint DLP architecture and their effective- ness in spotting and stopping encrypted data exfiltration is studied here. The study examines how these systems work, the methods they use and the problems they face in practice. The objective of this project is to provide an overview of the endpoint- based protection mechanisms in modern cybersecurity.

The paper analyses endpoint DLP architectures in the con- text of encrypted data exfiltration. Detecting ‘Data Exfiltration’ is easy with the use of endpoint-based monitoring, study indicates. The constraints of network-based systems are surpassed by the exploitation of data prior to encryption. Combining multiple detection techniques will enhance their effectiveness in detecting security threats. Even with challenges remaining, endpoint data loss preven- tion architectures are essential to modern cybersecurity.
