Problems solved by technology

[0013] (1) It cannot actively defend against legitimate users' malicious destruction and theft;
[0014] (2) The file protection strategy at the operating system level is not enough, and the file operation monitoring is not thorough enough, and it is easy to be filtered by anti-virus software and behavior monitoring software implemented at the kernel level;
[0015] (3) Poor timing of security protection

Embodiment

[0043] Example: such as figure 1 As shown in -6, the specific steps of the file security active protection method based on dual-drive linkage are as follows:

[0044] a) Use the INF file to install the driver to the target operating system, the driver exists as a service, and is set to start with the operating system;

[0045] b) Load the driver through the service management item of the operating system;

[0046] c) Read the preset file security protection rules into the rule chain;

[0047] d) Assign the IRP processing routine function entry to the corresponding dispatch routine array of DriverObject (driver object);

[0048] e) Fill in the Fast I / O processing routine, Fast I / O is a request without IRP caused by the cache manager call; the file filter driver writes for the DriverObject (driver object) in addition to the normal dispatch routine Another set of Fast I / O functions to monitor the cache;

[0049] f) Create a system thread, after obtaining the TCP / IP device obj...

Abstract

A file security active protection method based on double-drive linkage specially includes steps of: installing drives so as to enable service; loading linkage drives through service management items; reading preset file safety protection rules to a rule chain; giving an inlet of an intelligent resource planning (IRP) processing routine function to a Driver Object; filling a Fast input / output (I / O) processing routine; leading a file filtering drive to normally send the routine and monitor cache; building a system thread, obtaining transmission control protocol / internet protocol (TCP / IP) device objects, then starting a network drive comprising a transport driver interface (TDI) layer and a network driver interface standard (NDIS) layer, and performing monitoring action for operating files through network processes; and leading the file filtering drive to filter received IRP according to the rule chain and perform IRP-level monitoring on user action protected by the files. The file security protection technology based on kernel mode file system drive and network drive linkage effectively solves problems of file damage and file stealing caused by malicious file operation, network attack activities and Trojan virus.

Description

technical field [0001] The invention belongs to the field of communication and information security, in particular to an active file security protection method based on double-drive linkage. Background technique [0002] With the rapid development of the network, the continuous enrichment of mobile storage devices, and the further enhancement of the convenience of application software, the problems and challenges faced by file security protection have become more and more prominent. Only relying on manual management or monitoring software can no longer meet the existing security needs, because when the monitoring software detects malicious file operation behavior, the file has been destroyed or stolen, this passive traditional monitoring technology has its obvious disadvantages Weaknesses and drawbacks. Therefore, a set of monitoring technology based on active defense is needed to fundamentally solve the problem of file security protection. [0003] A lot of research has b...
