The modernization of rail control systems has resulted in an increasing reliance on digital technology and increased the potential for security breaches and cyber-attacks. Higher-level European Train Control System(ETCS) systems in particular depend on communications technologies to enable greater automation of railway operations, and this has made the protecting the integrity of infrastructure, rolling stock, staff and passengers against cyber-attacks ever more crucial. The growth in Internet of Things (IoT) technology has also increased the potential risks in this area, bringing with it the potential for huge numbers of low-cost sensing devices from smaller manufacturers to be installed and used dynamically in large infrastructure systems; systems that previously relied on closed networks and known asset identifiers for protection against cyber-attacks. This chapter demonstrates that how existing data resources that are readily available to the railways could be rapidly combined and mapped to physical assets. This work contributes for developing secure reusable scalable framework for enhancing cyber security of rail assets

Initiatives carried by companies, institutes and governments to flourish and embellish the Information and Communication Technology (ICT) among the public have led to its penetration into every walk of life. ICT enhances the efficiency of various systems, such as the organisation and transfer of data. However, with the digital and remote access features of ICT comes the motivation towards financial, political and military gains by rivals. Security threats and vulnerabilities in existing ICT systems have resulted in cyber-attacks that are usually followed by substantial financial losses. This study discusses the security in ICT from a business, economic and government perspective. The study makes an attempt to understand the seriousness of the security issues and highlights the consequences of security breech from an economic perspective. Based on the performed analysis, the factors behind these attacks are provided along with recommendations for better preparations against them.

Due to its nature, cyber security is one of the fields that can benefit most from the techniques of artificial intelligence (AI). Under normal circumstances, it is difficult to write software to defend against cyber-attacks that are constantly developing and strengthening in network systems. By applying artificial intelligence techniques, software that can detect attacks and take precautions can be developed. In cases where traditional security systems are inadequate and slow, security applications developed with artificial intelligence techniques can provide better security against many complex cyber threats. Apart from being a good solution for cyber security problems, it also brings usage problems, legal risks, and concerns. This study focuses on how AI can help solve cyber security issues while discussing artificial intelligence threats and risks. This study also aims to present several AI-based techniques and to explain what these techniques can provide to solve problems in the field of cyber security.

This paper presents a new national cyber security strategy (NCSS) covering the deterrence perspective from creation to implementation. With the aim of responding to and ensuring cyber security effectively, studies on which pathways should be followed and what methods should be used to develop, create, and implement a NCSS are being conducted in Turkey, as in all countries. In this context, by explaining the importance of cyber power, the need for cyber power to be considered as one of the elements of national power and the importance of providing security against cyber attacks with deterrence by cyber power are discussed, while a new and integrated approach for the creation and implementation of a NCSS and an authoritarian organizational structure responsible for this strategy is proposed. It can be concluded that the proposed effective and deterrent NCSS model and approaches might help to efficiently and effectively handle these issues for better management, control, and auditing for cyber security issues; provide new concepts for cyber security issues supported by cyber power and deterrence on this issue in the world; introduce integrated approach to cyber security strategies and policies on the stages of developing and implementing a NCSS; bring a number of issues to support cyber security and defence in different perspectives; and achieve a high degree of success, especially in terms of effectiveness and existing deterrence strategies and action plans of basic structure, with the proposed approach. Finally, it is expected that the proposed strategy, steps, and suggestions might help to improve cyber security issues and national strategies in near future to secure national assessment more than ever with a powerful concept of deterrence. In addition, this approach, which has been put forward for effective implementation of cyber security by ensuring better management, control, and supervision, can be easily used by all other countries.

With the emergence of network security issues, various security devices that generate a large number of logs and alerts are widely used. This paper proposes an alert aggregation scheme that is based on conditional rough entropy and knowledge granularity to solve the problem of repetitive and redundant alert information in network security devices. Firstly, we use conditional rough entropy and knowledge granularity to determine the attribute weights. This method can determine the different important attributes and their weights for different types of attacks. We can calculate the similarity value of two alerts by weighting based on the results of attribute weighting. Subsequently, the sliding time window method is used to aggregate the alerts whose similarity value is larger than a threshold, which is set to reduce the redundant alerts. Finally, the proposed scheme is applied to the CIC-IDS 2018 dataset and the DARPA 98 dataset. The experimental results show that this method can effectively reduce the redundant alerts and improve the efficiency of data processing, thus providing accurate and concise data for the next stage of alert fusion and analysis.
