Task scheduling method of event injection engine based on multilevel feedback queue

Abstract

The invention belongs to the technical field of event injection of a computer system, in particular to a task scheduling method of an event injection engine based on a multilevel feedback queue. The method includes the steps that a scanner scans a target system according to user commands or system control signals, and a scanning result comprising all vulnerability types of the target system is returned; the scanning result is analyzed according to all vulnerabilities or user requirements, and types of batch events needing injecting are determined; the scanner sends information needing injecting of the types of the batch events to an event model library; the event model library receives the information, of the types of the batch events, sent by the scanner, and corresponding events are selected according to the types of the batch events. The method has the advantages that the application range is wide, feedback cost is small, compatibility is good, the utilization rate of the event injection engine is high, and batch event injection is more flexibly, efficiently and reasonably achieved.

Description

Technical field [0001] The invention belongs to the technical field of event injection of computer systems, and particularly relates to a task scheduling method of an event injection engine based on a multi-level feedback queue. Background technique [0002] Event injection technology refers to the process of injecting events into the target system, simultaneously observing and recovering the system's response information to the injected events and analyzing the recovered information, and then providing relevant results to the tester. In the evaluation of computer system usability, event injection technology can not only evaluate some specific indicators of the system, but also evaluate the impact of non-faulty and human factors on the system during system operation. At present, the research of event injection technology is mainly focused on the way that the event injection engine simply injects a single event sequentially or discretely injects events one by one into the target s...

Problems solved by technology

[0004] From the above analysis, it can be seen that the main shortcomings of event injection research at this stage are: most of them use the method of simply injecting a single event into the target system sequentially by the event injection engine or discretely injecting events one by one, resulting in low efficiency and high overhead.
