Reseach On Implementation Of Information Security System Based On File System Filter Driver

With the rapid development of computer science, security has become a problem that can not be ignored. The importance of information security is gradually being recognized and data security in information security is a core issue. So how to protect data has become a very important research topic in information science. Once failure occurs, backuping data immediately is very important, if we backup data quickly the loss will be reduced, so we have to solve problems in real-time data backup, Currently continuous data protection technology enables real-time data backup, so the technology has now become a hot topic in data protection.In this paper, we will use the file system filter driver development framework based on Minifilter to monitor process’ s requests for access to data continuously and using this development method, we will realize real-time backup for data. This goal is achived by embedding the file system filter driver in the kernel, so each time a change in the data file will be strictly recorded, thereby preserving the integrity of backup data. Furthermore, because the file is backed up during every visit to this file, it is possible to ensure real-time data backup. Because the security of back-up data can not be underestimated, so in this article back-up data is also encrypted. This will be able to ensure the security of back-up data.After implementing the system, we also design different test cases to test the functionalities of the system to ensure the real-time data backup and data security.In addition in the design of the system of the time this article also presents a new access control strategy, through the strategy to protect the backup data, backup data protection in the operating system level, improved the security of the backup data, thereby preventing illegal access to the backup data, so as to ensure the integrity of the data and the data is not stolen.In this paper, we implement information security system based on the Minifilter file system filter driver development framework which enables real-time data backup. The back-up data can also be encrypted and access to the back-up file can be controled at the operating system level. This will completely guarantee the security of the data. Compared with traditional data backup system, our system control the request according to the process’ s access right. In general, access can be controlled in accordance with the built-in access control model. These are the core competitiveness of our system.
