基于过滤驱动技术设计的数据防篡改系统及其测试验证

Design and verification of a data tamper-proof system based on filter-driven technology

计算机的独立性和模块化特点使得信息安全问题日益突显,为应对一系列信息安全攻击,提出了一种基于过滤驱动技术的计算机关键文件固化系统。该系统利用了计算机文件底层隐藏的NTFS文件结构特性,通过操纵操作系统底层文件实现了对关键文件的高效保护。系统运用了先进的过滤驱动技术,通过拦截和分析IRP流,能够提前预判写操作的文件。对所有受保护的网站目录的写操作进行即时截断,从而强化了文件的安全性。系统进一步限制对关键文件的修改权限,阻止了未经授权的篡改,还能够监测和阻止潜在的网络攻击,为计算机系统提供了全面的安全保障。系统不仅提高了关键文件的抗篡改能力,而且在篡改写入文件之前就能够主动阻止,成为一款高效的安全软件系统。通过该系统的应用,用户能够更加可靠地保护计算机系统中的关键数据,有效降低了信息安全风险。

The independence and modularity of computers have made information security issues increasingly prominent.In order to deal with a series of information security attacks,a key computer file solidification system based on filter drive technology was innovatively proposed.This system takes advantage of the NTFS file structure characteristics hidden at the bottom of computer files,and achieves efficient protection for key files by manipulating the underlying files of the operating system.The system uses advanced filtering driver technology,and by intercepting and analyzing IRP flows,it can predict files write operations in advance.Besides,instant truncation of write operations to all protected website directories enhances file security.The system further restricts the modification rights to key files,prevents unauthorized tampering,and can also monitor and block potential network attacks,providing comprehensive security protection for the computer system.The system not only improves the anti-tampering ability of key files,but also actively blocks tampering before it is written to the files,making it an efficient security software system.Through the application of this system,users can more reliably protect key data in computer systems and effectively reduce information security risks.
