Review of Dependability Assessment of Computing System with Software Fault-Injection Tools

Abstract

The importance of systems dependability is the main motivation for developing fault injection methods (because fault injection is one of the most important ways to assess system dependability). Dependability assessment automatically generates mathematical models of reliability based on simple representations of the parameters of the functions of the system components, service and logistics functions, subsystem order structures, and critical functions. If necessary, it is also possible to develop a detailed mathematical model for various aspects of the stability system behavior. Package evaluation functions include accurate and approximate solution methods that can be used to quantify the reliability of components, subsystems and operations, maintenance functions, and availability with respect to potential project design. In this research, several fault injection tools and software system dependability assessment are rewired. The general method of dependability assessment for software systems under testing is a fault injection tool. Dependability assessment based on the fault injection tool can be done by inserting the faults into a system and monitoring that system for determining its behavior and response. Practically, experimented fault injection techniques can be grouped into fault injection implementation by hardware, software, simulation, emulation, and hybrid fault injection techniques. This study aims to measure the weakness that affects dependability attributes by presenting a survey on the implementation of software fault injection approaches for three major levels (interface, distributed systems, and operating systems levels) with dependability applications and an overview of the different injection tools.

FIBR-OSS: fault injection model for bug reports in open-source software

“…Because the process of injecting a real error or fault is very expensive for computer parts of software and hardware, we have relied on learning of open-source software and their preparations to receive faults and predict them through these faults reports in the event that one of these errors/faults target the systems really during the system execution period. Through the process of research and study of tools previously built to inject faults that were published in our review of related works [8], there was a need to build a new injection tool through which we can inject faults to an integrated system that includes an operating system, a web browser, database software, and the web language software.…”

“…Through studying and analyzing the reviews and publications on the subject of this project in [8], we found that faults injection is a confirmed and significant method for assessment of software dependability. To inject faults, researchers and developers have created several new techniques that can be performed in hardware, software, or both.…”

Financial Literacy and Financial Capability: Interdependence of Concepts and Possibilities to Form Them in a School Course of Mathematics

“…Financial literacy allows a person not to be dependent on circumstances, the will of other people, or the system. An educated person himself can choose the paths in life that will be most attractive to him, creating the material basis for the further development of society" (Zelentsova, Bliskavka and Demidov, 2012;Caplinska & Ohotina, 2019;Abd & Behadili, 2019).…”
