| Popis: | 103 Network is an indispensable technology in our life. However, any computer in the network may be easily under attack by hackers, like Web page replacement, data loss; that’s to say, the confidential data is tampered, and even the hard disk is stolen by malicious users. All these human factors are difficult to defense for valuable data on computing devices. There are several solutions in current market for computer data protection, but they cannot completely solve the problems mentioned above. If malicious users enter the system’s safe mode, it means the system would open the door for free access to all, and it’s more difficult to defense the malicious access. Since the user’s data access activity is only controlled in user mode for current operating systems, for this characteristic, this thesis attempts to implement a FSG (File System Guardian) system in kernel mode to filter the users’ data access activity on two prevalent operating systems of Microsoft Windows and open-source Linux. They respectively use techniques of filter driver for Windows and hooking system call table for Linux to protect the files comprehensively. On the other hand, the proposed FSG system also encrypts the content of protected file via famous RC5 to ensure the protection reliability and then prevent the possible crisis caused by malicious users. |
