Supervisory Control and Data Acquisition (SCADA) systems are the underlying monitoring and control components of critical infrastructures, such as power, telecommunication, transportation, pipelines, chemicals and manufacturing plants. Legacy SCADA systems operated on isolated networks, that made them less exposed to Internet threats. However, the increasing connection of SCADA systems to the Internet, as well as corporate networks, introduces severe security issues. Security considerations for SCADA systems are gaining higher attention, as the number of security incidents against these critical infrastructures is increasing. In this survey, we provide an overview of the general SCADA architecture, along with a detailed description of the SCADA communication protocols. Additionally, we discuss certain high-impact security incidents, objectives, and threats. Furthermore, we carry out an extensive review of the security proposals and tactics that aim to secure SCADA systems. We also discuss the state of SCADA system security. Finally, we present the current research trends and future advancements of SCADA security.

“…In a highly competitive psychological environment, behaviors might change as individuals could be manipulative, harsh, and hide the information because these behaviors pursue more benefits and power in the work environment. In the competitive psychological climate circumstance "organization insider" employees who think about self-identity, believe that their goal attainment has to be better than others, and want oneself to be the winners, and others to be the failures (Bell, Rogers, & Pearce, 2019;Mukherjee, Huang, Neidhardt, Uzzi, & Contractor, 2019;Garcia, Tor, & Schiff, 2013;Gibson, Harari, Marr, & Processes, 2018). However, employees' perceived insider status can originate from the individual's self-value, based on their identity.…”

“…The reason for selecting perceived insider status is, it mediates the relationship between competitive climate to represent people's social identity and self-conception as an insider of organization strengths rather than the weaknesses in the competitive work environment aspects. Most studies have labeled that perceived insider status demonstrates a positive relationship with ethical behaviors (Bell et al, 2019;Caron, Asselin, Beaudoin, & Muresanu, 2019;Hongli Wang et al, 2017). We, whereas, have worked on perceived insider status in a reserved-way.…”

Summary The purpose of this study is to explain why employees in financial companies in Sri Lanka are likely to engage in unethical pro-team behaviors and how transformational leaders involve controlling unethical pro-team behaviors in a competitive work environment. The study employed a quantitative approach to investigate the association between the competitive psychological climate and perceived insider status on unethical pro-team behaviors. The authors collected data from 426 sales representatives at a finance company in Sri Lanka and tested hypotheses using Structural Equation Modelling analyses through Smart PLS version 3. The results indicate that competitive psychological climate and perceived insider status are positively associated with unethical pro-team behaviors. Further, the transformational leadership’s moderation is negatively significant on the relationship between competitive psychological climate and unethical pro-team behaviors. The study has shown that the leader will delegate more responsibility to the employee, associated with increased employee empowerment and high-quality, ethical behaviors. Besides, it contributes to the literature as of the new theoretical base and offers practical implications with the richer view of a nomological link between the leader, competitive employee, and competitive work environment.

“…The weakest link in any information security chain is always considered to be the human factor, and this has resulted in increasing attention being paid to human factors in the context of insider threats; mainly where the use of security technologies has failed to protect organisations from malicious insider threats (Herath and Rao, 2009;Hadlington, 2017). It has been argued by researchers that insiders have specific psychological characteristics (behavioural indicators) that need to be considered when measuring the severity of insider threat risk (Nurse et al, 2014) (Bell et al, 2018). In this aspect, Wood's assumption (Wood, 2000), is used to calculate each authorised user's psychological profiling level.…”

Insider threat protection has received increasing attention in the last ten years due to the serious consequences of malicious insider threats. Moreover, data leaks and the sale of mass data have become much simpler to achieve, e.g., the dark web can allow malicious insiders to divulge confidential data whilst hiding their identities. In this paper, we propose a novel approach to predict the risk of malicious insider threats prior to a breach taking place. Firstly, we propose a new framework for insider threat risk prediction, drawing on technical, organisational and human factor perspectives. Secondly, we employ a Bayesian network to model and implement the proposed framework. Furthermore, this Bayesian network-based prediction model is evaluated in a range of challenging environments. The risk level predictions for each authorised users within the organisation are examined so that any insider threat risk can be identified. The proposed insider threat prediction model achieved better results when compared to the empirical judgments of security experts
