Cyber-Physical Systems refer to systems that have an interaction between computers, communication channels and physical devices to solve a real-world problem. Towards industry 4.0 revolution, Cyber-Physical Systems currently become one of the main targets of hackers and any damage to them lead to high losses to a nation. According to valid resources, several cases reported involved security breaches on Cyber-Physical Systems. Understanding fundamental and theoretical concept of security in the digital world was discussed worldwide. Yet, security cases in regard to the cyber-physical system are still remaining less explored. In addition, limited tools were introduced to overcome security problems in Cyber-Physical System. To improve understanding and introduce a lot more security solutions for the cyber-physical system, the study on this matter is highly on demand. In this paper, we investigate the current threats on Cyber-Physical Systems and propose a classification and matrix for these threats, and conduct a simple statistical analysis of the collected data using a quantitative approach. We confirmed four components i.e., (the type of attack, impact, intention and incident categories) main contributor to threat taxonomy of Cyber-Physical Systems

To maintain the attendance records, several government organisations and educational institutions in many countries still depend on the paper-based attendance approach. This approach has presented several disadvantages such as time-consuming and wastage of environmental resources. There is a necessity to change these traditional methods of attendance recording with more efficient ones. Thus, many works have been done in this direction. Moreover, this study aims to analyse the most recent studies on automated attendance systems regarding the timeline. Our critical review has highlighted studies in the existing literature concerning technology, application domain, and main findings. Moreover, shed light on most numerous studies on any of three previous aspects.

In this paper, an investigation of the power consumption is done by making a comparison between static and dynamic WSNs. We have compared the results of the static network with the results of the dynamic network. Static and dynamic wireless Sensor networks have the same architecture (Homogenous) and proposed protocol. Depending on the suggested protocol, the simulation results show that the energy consumption in the static wireless sensor network was less than the dynamic wireless sensor network. However, moving the sensors in the dynamic WSN present real improvement in delivering packets to the base station. In the proposed routing protocol, transmitting data process is done in a hierarchal way. Cheap sensors are introduced and deploy them intensively to improve the QoS in the network. The final results and the conclusion are reported.

Human-Computer Interaction (HCI) is concerned with how humans work with computers and how technologies can accommodate the needs of users to meet their goals. The early phases of Virtual Reality (VR) often involved headmounted computers in which users immersed themselves, as they could act, perceive, and interact with a three-dimensional world. This paper has two objectives: to conduct a detailed review of VR trends (previous, current, and forthcoming) and to highlight the applications and obstacles that affect each trend. Reliable survey data was obtained from sources such as ISI, Scopus, Springer, IEEE, and Google Scholar, as well as websites. The main contributions of this work are: (1) analysis and summary of VR trends in the past, present, and future, (2) details of the technical limitations of each trend and explication of their applications, technological requirements, and currently available solutions, (3) illustration of the direction, developments, issues, and challenges for each trend (previous, current, and future), (4) identification of the direction and important trends that require more comprehensive studies by future researchers.

At present, Web applications have been used for most of our life activities increasingly, and they affected by Structured Query Language Injection Attacks (SQLIAs). This attack is a method that attackers employ to impose the database in most of the web applications, by manipulate SQL queries, which sent to the Relational Database Management System (RDBMS). Hence, change the behavior of the applications. In This paper, developing Web Application SQLI Protector (WASP) tool in real-time web application to detect SQL injection attacks in stored procedures. Then, evaluated and analyze the developed tool respect to efficiency and effectiveness in practices. The propose technique uses realtime based on positive tainting, accurate and efficiency taint propagation, and syntax aware evaluation of the query strings at the application level to detect illegal queries before they reach at the database by using Microsoft ASP.NET. The developed tool effective due to it capable of detect and stop all SQLI attacks in real-time environment and did not generate any false negative, a few-false positive values in the results and impose minimal deploy requirements.

Generally, qualifications for personnel who work in IT field and network operators in particular are considered for many purposes, includes: measuring whether a specific employee capable to handle a certain job or not and it can be made as a direction in order to develop human esources. Whereas, the qualifications are different based on the needs of organizations and views. Furthermore, several influence factors for qualifications in the literature revealed have been employed for industry and academia domains such as, skill, knowledge, ability, attitude, certification, education, and experience. However, few studies have been investigated the impact of the qualifications gap for the previous elements especially inside public universities. On other hand, many studies have determined the values for each of the certification, education, and experience as qualifications for IT personnel. In this paper, conduct a new model to measure the influence for each of Certification Lack (CL), Education Lack (EL1), and Experience Lack (EL2) on the qualifications gap for network technicians inside Baghdad public universities. Data have collected by on-line survey from seventy respondents in order to analyze and test empirically the proposed hypotheses. Education Lack is the highest influencer of qualifications gap followed by Experience Lack, and Certification Lack are the findings of the proposed model.

Web applications have become widely pervasive in all types of Internet-based services. Thus, security is one of the major concerns as most web applications suffer from vulnerabilities, making them attractive targets for security attacks. Structured Query Language Injection Attack (SQLIA) on stored procedures poses serious threats in the underlying database of any application. This article presents the methodological issues of developing a web application SQLI protector tool to detect stored procedures of SQLIAs. Our technique uses real-time settings based on positive tainting approach, accurate and efficient taint propagation and syntax-aware evaluation of the query strings at the application level are used to detect illegal queries before they reach the database. Then, the proposed tool is evaluated based on its efficiency and effectiveness in practices. In addition, detection techniques used are also analysed. The developed tool is effective given its capability to detect and stop all SQLIAs in a real-time environment.
