Embodiment Construction

[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0017] figure 1 The implementation principle of the present invention is described, and a detailed working process of the distributed mission-critical system repentance method based on operation interception is provided:

[0018] Step 1: Make redundant backups of important program files and data files of the distributed critical mission system to ensure the integrity and recoverability of the initial state information of the system. This way, even in the "worst" case where the repent method doesn't work, the system can still be restored to its original state.

[0019] Step 2: The operation interceptor intercepts the system operation in real time, captures the operation parameters and operation data, and writes them into the operation log.

[0020] Step 3: The operation analyzer analyzes new operations in real time. The operation monitoring module monitors chang...

Abstract

The invention provides an operation intercept based repentance method of a distributed critical task system, comprising the following steps of: firstly carrying out redundancy backup on important files of the system to ensure the recoverability of data information; secondly intercepting the operation information of the system by an operation intercepter in real time and writing into an operation log; and analyzing captured operation records by an operation analyzer and writing unrecoverable operation or operation which does not need to be recovered into redundant files by an operation storage and processing the operation which needs to be recovered by a repenter. When the system is faulty, the repenter carries out repentance recovery on the system through three continuous steps of operation rollback, operation restoration, operation resetting and solves the problem of inconsistency possibly generated in the repenting process through a consistency manager according to a graded compensation strategy.

Description

technical field [0001] The invention relates to an information security protection method applied to a distributed critical mission system with high security standards. Background technique [0002] Due to the increasing complexity, heterogeneity, and dynamics of the system, as well as the continuous innovation of external attack methods, it is becoming increasingly difficult for operators to manage and maintain distributed mission-critical systems, and frequent operational errors cause the system to always face software interruptions, How to ensure the continuous and reliable operation of distributed mission-critical systems has become a severe challenge due to the threat of system failures such as data loss and even system crashes. In response to this problem, early researchers made some meaningful explorations from the perspective of backup and recovery. For example, the technical solution in the patent with the publication number CN1517918 enables the system to restore ...
