Core Viewpoint - The article emphasizes the importance of proper use and management of shredders to protect sensitive information, highlighting that even seemingly secure shredders can pose a risk of information leakage if not used correctly [1][4]. Group 1: Common Operational Vulnerabilities - Choosing shredder models based on convenience rather than security standards can lead to inadequate shredding results, increasing the risk of sensitive information being recovered [2]. - Batch processing of sensitive and non-sensitive documents together can create a significant risk if the mixed shreds are not handled according to destruction standards, potentially allowing malicious individuals to extract sensitive information [2]. - Lack of oversight in the shredding process can lead to security breaches, as some units neglect to monitor the shredding process or maintain proper records of destroyed documents, making it difficult to trace leaks [2]. Group 2: Recommendations for Secure Shredding - Selecting shredders that meet confidentiality standards and are equipped with features like automatic jam stop, capacity alerts, and residue detection is crucial for ensuring effective destruction of sensitive documents [6]. - Establishing a robust management and oversight system for shredders, including appointing responsible personnel and conducting regular training for staff on proper shredding practices, is essential to mitigate risks [6]. - Regular maintenance and checks of shredders are necessary to ensure they operate effectively and securely, including cleaning and professional servicing to prevent malfunctions that could lead to information leaks [6].

——批量处理"赶进度"，混合粉碎风险大。部分人员为节省时间，将涉密文件与非涉密文件混合批量粉碎，混合粉碎后产生的纸屑若未按销毁涉密载体标 准集中处理，而是与普通垃圾一同清运，一旦被别有用心之人分拣筛选，会存在涉密信息被提取还原的风险。 ——流程把控"缺监管"，泄密隐患需防范。碎纸机使用的全流程监管是防止泄密的关键，但部分单位存在"重使用、轻监管"的问题。例如，工作人员将涉 密文件放入碎纸机后便离开现场，期间若发生碎纸机故障或他人误操作，无法及时发现和处置；某些单位未建立涉密文件销毁登记制度，对粉碎的涉密文 件名称、份数、密级、操作人员、处理时间等信息未如实记录，一旦出现泄密事件，无法追溯源头；此外，淘汰的涉密碎纸机若未按涉密设备报废流程处 理，极易被不法分子获取残留的涉密信息。 国家安全部今天发布安全提示文章，在日常办公中，碎纸机通过物理切割方式将记载有敏感信息的纸张粉碎，从而保护国家秘密安全。但随着窃密手段不 断迭代，看似可靠的碎纸机，正成为泄密风险的隐秘源头。有公开报道显示，有专业技术能通过扫描碎纸颗粒的图案、颜色，并运用相关软件恢复关键内 容，甚至可还原约70%的碎纸内容。因此，正确使用碎纸机，不仅是办 ...
