AI Technical Summary

Technical Problem

Existing methods for managing the outward distribution of files are insufficient to effectively address complex security threats, cannot conduct dynamic risk assessments and controls, and traditional encryption and permission settings are easily cracked, making it impossible to detect and address potential security risks in a timely manner.

Method used

By employing dynamic risk assessment, behavioral baseline models, and adaptive response strategies, combined with encryption keys, policies, and a key service center, the system monitors the file usage environment in real time, generates unique file identifiers, decrypts file content in memory, intercepts persistent operations, and utilizes decoy file fragments and encrypted beacons for proactive defense.

Benefits of technology

It achieves dynamic security protection for file transfer and viewing, can accurately identify risks and respond adaptively, improves the ability to deal with unknown threats, ensures that file content is not leaked, and provides a comprehensive security monitoring and tracking mechanism.

Abstract

The application discloses a file sending management method, system, medium and product, and relates to the field of data management.The method comprises the following steps: configuring a security policy for a basic file to be sent on a management end, encrypting the basic file by using an encryption key to obtain a target file; encapsulating the target file, a preset file management middleware and a unique file identifier to generate a controlled executable container; collecting current environment context data of a client through the controlled executable container; obtaining a risk assessment result through the environment context data and a trusted environment feature; when a first identifier in the risk assessment result is passed, issuing a decryption token to the controlled executable container, and determining the strength of an adaptive response strategy to be executed according to a second identifier in the risk assessment result. The above technical solution improves the security of the sent file in the transmission and reading process, and prevents the file from being illegally persisted and leaked.
