INFORMATION LEAKAGE PREVENTION SYSTEM AND METHOD OF INFORMATION LEAKAGE PREVENTION Russian patent published in 2024 - IPC G06F21/55 H04L41/894 

FIELD: computer engineering.

SUBSTANCE: data leakage prevention system comprises a server located inside a corporate network of an enterprise, wherein for each data transmission channel an interception subsystem is configured, and each intercepted message transmission or document access event is transmitted to a data extraction subsystem, which constructs an event parsing tree, wherein the parsing tree root is the intercepted document, and the remaining nodes contain information that was transmitted as part of the intercepted document, the information in which is text or image, result of operation of subsystem of data extraction from event is transmitted to subsystem of data analysis from events, which performs analysis of obtained data by application of analysis technologies, result of operation of subsystem of data analysis from events is transmitted to subsystem of application of security policies, where security policies impose configuration of security policies on properties of intercepted data by comparing policy values with result of data analysis and other attributes of events.

EFFECT: reduced time for detection of full scenario of development of events, which are potentially capable to lead to leakage of sensitive information.
