Embodiment Construction

[0014] combine Figure 4 , the present invention discloses an information asset protection method based on intrusion tolerance. Firstly, the core data and service status are detected and monitored. Make an objective evaluation of the status and upload it to the response and fault handling module of the system in the form of an event, and then start the local fault isolation and system restoration and reconstruction mechanism according to the result of the system status evaluation to ensure the confidentiality of core information assets. The invention introduces intrusion tolerance into the design of a single host, and provides basic self-diagnosis, fault isolation, restoration and reconstruction, and secure communication capabilities for a single system in an environment with limited resources.

[0015] like figure 1 , an information asset protection method based on intrusion tolerance, the specific process is as follows:

[0016] (1) The status detection module adopts a dyn...

Abstract

The invention discloses an information asset protection method based on intrusion tolerance. The information asset protection method comprises the following steps: firstly detecting and monitoring core data and service states; by virtue of an evaluation model carried by a state evaluation module and a threshold value which is preset in a configuration file by a user, performing objective evaluation on the system state and uploading the objective evaluation result to a response and fault handling module of a system in the form of events by using the state evaluation module; and then according to the system state evaluation result, starting local fault isolation and system recovery reconstruction mechanisms so as to guarantee the confidentiality of core information assets. The information asset protection method has the beneficial effects that the intrusion tolerance is introduced into an individual host so as to provide basic functions such as auto-diagnosis, fault isolation, recovery reconstruction and safety communication for each system in a resource constraint environment.

Description

technical field [0001] The invention belongs to information asset protection technology related to the field of information security, in particular to an information asset protection method that uses a state transfer algorithm for state control and a multi-factor fuzzy model for comprehensive state evaluation to realize an intrusion tolerance framework. Background technique [0002] With the increasing popularization of informatization, enterprises or institutions have established internal networks. Network erection and information system construction have brought many conveniences to these units, such as resource sharing, office automation, and convenient information transmission, etc., which have greatly improved work efficiency. However, at the same time, the number of leaks reported by the media continued unabated, including the theft of core technologies of enterprises, which led to the development and growth of competing enterprises, resulting in serious economic losse...
