Abstract


Now we are in the "info era", we make millions of information every day, how to keep the security of all these information becomes the focus in the research of computer science. When we talk about the information security, it is always referring to hacker or virus, but in the most cases the safe problem is not caused by hacker or virus but by the workers in the company. Because the inside people has much convenience and possibility to steal the information or lost the media which keep the data. On the other side, most of current security products are focus on hacker and virus and can’t keep the information from leaking.Based on these situations, the security of data in computer system is put forward. By combining the technology of file system filter driver, WDM filter driver and the technology of network monitor, the system can protect the data in computer very well. The system’s advantage I design mainly in the follows:(1) After encrypting the data in storage media, I add part of the key information at the end of the file, so it solves all the problems with the methods which the key information and the file data are separate.(2) When monitor the network, I apply three filters which are in the application layer, transport layer and network layer, this solution can manage the network data perfectly.(3) When monitor the peripheral equipment, I set the monitor policy very reasonably such as according to the bus type, device type or the device’s ID, so it can control all the devices very well.
