A File System Protection Scheme Based on File Filter Driver and TrueCrypt

近几年,随着计算机网络的高速发展,对于计算机信息安全的重要性越来越被强调,尤其是政府和企业的内部资料显得尤为重要。但是传统的的杀毒软件和木马查杀软件的效果并不好,对木马和病毒的行为分析和特征库往往会因为创新性病毒的存在,因无最新的特征库和行为导致效果并不好,故采用一种全新的基于文件过滤驱动的文件重定向和TrueCrypt的虚拟磁盘的保护方式来对用户的机密文件进行保护。

In recent years, with the rapid development of computer network, the importance to computer information security is becoming more and more increasingly being emphasized. Especially the government and enterprise internal information is particularly important. But the tra- ditional antivirus software and Trojan Avira software effect is not good, to Trojan and virus behavior analysis and the characteristic database often because innovation virus exists, because without the latest feature library and behavior cause effect is not good. So we use a new virtual disk file system filter driver of file redirection and TrueCrypt protected mode on the user＇s confidential documents based on protection.
