Research on Risk Detection and Cleansing Technology for OOXML During Cross-Network Transmission

With the increasing frequency of data exchange, the security issue of cross-network file transfer has become more prominent. Safe data transmission requires controlling the sensitive information in documents to prevent the security issues caused by malicious and hidden information along with the document carrier. Based on the structural research of OOXML files, referring to the NSA's disinfection guidelines for OOXML files, this paper analyzes the information hiding risks in OOXML and summarizes the methods and suggestions for file risk detection and disinfection, aiming to conduct in-depth detection and cleansing of OOXML files and provide security guarantees for cross-network transmission of data files.
