Marine Vessels

Autonomous marine vessels are the way forward to revolutionize maritime operations. However, the safety and success of autonomous missions depend critically on the availability of a reliable positioning system and time information generated using global positioning system (GPS) data. GPS data are further used for guidance, navigation, and control (GNC) of vehicles. At a mission planning level GPS data are commonly assumed to be reliable. From this perspective, this article aims to highlight the perils of maritime navigation attacks, showing the need for the enhancement of standards and security measures to intercept any serious threats to marine vessels emanating from cyber attacks and GPS spoofing. To this end, we consider a case where a cyber attacker blocks the real GPS signals and dupes the GPS antennas on board the marine vehicle with fake signals. Using the Nomoto model for the steering dynamics of a marine vessel and exploiting tools from linear control theory we show analytically, and verify using numerical simulations, that it is possible to influence the state variables of the marine vessel by manipulating the compromised GPS data.

Phishing Attacks

Introduction. With the rapid adoption of computer and networking technologies, educational institutions pay insufficient attention to the implementation of security measures to ensure the confidentiality, integrity and accessibility of data, and thus fall prey to cyber-attacks. Methods. The following methods were used in the process of writing the article: methods of generalization, analogy and logical analysis to determine and structure the motives for phishing attacks, ways to detect and prevent them; statistical analysis of data – to build a chronological sample of the world's largest cyber incidents and determine the economic losses suffered by educational institutions; graphical method – for visual presentation of results; abstraction and generalization – to make recommendations that would help reduce the number of cyber scams. Results. The article shows what role cyber security plays in counteracting phishing scams in the educational field. The motives for the implementation of phishing attacks, as well as methods for detecting and preventing them, have been identified and regulated. The following notions as "phishing", "submarine" and "whaling" are evaluated as the most dangerous types of fraud, targeting both small and large players in the information chain of any educational institution. An analytical review of the educational services market was conducted and a chronological sampling of the largest cyber incidents that occurred in the period 2010-2019 was made. The economic losses incurred by colleges, research institutions and leading universities in the world were described. It has been proven that the US and UK educational institutions have been the most attacked by attackers, somewhat inferior to Canada and countries in the Asia-Pacific region. It is found that education has become the top industry in terms of the number of Trojans detected on devices belonging to educational institutions and the second most listed among the most affected by the ransomware. A number of measures have been proposed to help reduce the number of cyber incidents. Discussion. The obtained results should be taken into account when formulating a strategy for the development of educational institutions, as well as raising the level of awareness of the representatives of the academic community in cybersecurity. Keywords: phishing, cyber security, cyber stalkers, insider threat, rootkit, backdoor.

C4ISR stands for Command, Control, Communications, Computers, Intelligence, Surveillance & Reconnaissance. C4ISR systems are primarily used by organizations in the defense sector. However, they are also increasingly being used by civil sector organizations such as railways, airports, oil, and gas exploration departments. The C4ISR system is a system of systems and it can also be termed as network of networks and works on similar principles as the Internet. Hence it is vulnerable to similar attacks called cyber attacks and warrants appropriate security measures to save it from these attacks or to recover if the attack succeeds. All of the measures put in place to achieve this are called cyber security of C4ISR systems. This chapter gives an overview of C4ISR systems focusing on the perspective of cyber security warranting information assurance.

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.

In recent years, the cyber security scenario has transformed predominantly from conventional response-based security mechanisms to proactive security strategies. And this transformation is still continuing which is shifting it from proactive security strategies to cyber immunity which eliminates the cyber threats by introducing stringent and adaptive security measures. In the process of developing new security algorithms/procedures, accurate modelling and effective simulation play a vital role for the robustness and effectiveness of proposed system. It is also necessary to analyze the behaviour of proposed system against multiple types of known cyber attacks. This paper focuses on the existing network testbeds for an effective analysis and monitoring while proposing a new network testbed for examining new security concepts like cyber immunity. The proposed network testbed is designed to incorporate the methods and procedures of Nature-inspired Cyber Security to accommodate the adaptive responses against the sophisticated and ever-advancing cyber attacks. The proposed testbed provides customizable analytical tool to design, test and examine the new security algorithms through a rich set of attack scenarios. It also allows developers to design, implement, and evaluate their defensive techniques with library support.
