Cross-network illegal external connection monitoring method based on SM optical disc carrier whole life cycle management

Abstract

This invention discloses a cross-network unauthorized external access monitoring method based on the full lifecycle management of SM optical disc carriers, belonging to the field of controlled media management technology. The method includes: registering burner assets and establishing binding relationships in a local area network (LAN) management platform; receiving SM optical disc burning tasks and completing approval association; the burning client obtaining the WAN detection address and alarm address, encrypting the SM file and writing it to the optical disc, and writing a self-starting monitoring applet and encryption address configuration information; triggering the execution of the self-starting monitoring applet and performing access detection when the optical disc is inserted into the terminal; when WAN access is possible, collecting evidence packets and reporting to the alarm backend, while simultaneously blocking decryption access to the SM file; when WAN access is not possible but decryption conditions are met, allowing decryption access to the SM file. By implementing closed-loop management of SM optical discs, the method improves the proactive detection and real-time blocking capabilities of cross-network unauthorized reading, and enhances the effectiveness of audit evidence collection and accountability.
