The great revolution of technology and its fast growth have led to a cyber space increasingly vulnerable to cyber-attacks. For this reason, cyber security becomes paramount to protect our cyber space by presenting and implementing important solutions to protect sensitive data from malicious persons. Thereby various measures of protection have been developed and aim to minimize the risks and damages of attacks. Among them, cryptography plays a vital and crucial role in protecting sensitive transmissions and electronic exchanges through complex networks. Numerous scientific studies have emerged with the advent of the cloud and the Internet of Things (IoT); all of them have expressed a strong need for building secure, efficient and fast cryptosystems targeting confidentiality, integrity and authentication. The last two objectives are essentially built on hash functions which are the main components of many applications and secure networks. The purpose of this paper is to give recent advances of lightweight cryptographic solutions that meet the requirements of constrained systems, and to present a study, in terms of security, energy-consuming and efficiency, of the main hash functions standardized by NIST (National Institute of Standards and Technology). In the end, the paper will give a comparison between the studied hash functions aiming to come up with a recommendation of good lightweight hash functions suitable for implementation in an IoT framework.

Cyber deterrence by denial strategy can be practised by the state by making it hard for adversaries to succeed any attempt of attacking. It was practised during nuclear deterrence strategies as well as in many other conventional deterrence. This paper argues the functionality of cyber deterrence by denial in deterring cyber threats. In this paper, our attempt is to define cyber deterrence by denial, model it, explore operational roles of cyber security technologies in approaching deterrence by denial within cyber space. Model analysis shed lights over practicing deterrence by denial and its vital role in understanding how efficiently denial can work in maximize failure of any attack which will impact in maximizing cost of cyber attacks to the attacker. Due to limitations in cyber security technologies, unknown cyber threat might not be deterred with assumed approach. Proposed model confirmed that deterrence by denial strategy might works in deterring known cyber threats within instrumental model. As for the benefit of enhancing deterrence in cyber space there is a serious need to reduce the tendency to ignore exploring this strategy.


Subject China and the global internet governance regime. Significance Cyber security was a leading topic at the Global Conference on Cyberspace that took place on April 16-17 in The Hague. As online tensions escalate and cyber attacks grow in prevalence, the direction of Chinese policy will be crucial in determining the future of the global internet. At the same time, the United States has lost much political capital and bargaining power. Impacts China may try to establish alternative internet structures and systems. China's conception of national sovereignty will hold back the cooperation procedures necessary to manage cyber space incidents. Without international cooperation, countries and companies may seek to retaliate against cyber attacks rather than merely ward them off.

Purpose The common implementation practices of modern industrial control systems (ICS) has left a window wide open to various security vulnerabilities. As the cyber-threat landscape continues to evolve, the ICS and their underlying architecture must be protected to withstand cyber-attacks. This study aims to review several ICS security assessment methodologies to identify an appropriate vulnerability assessment method for the ICS systems that examine both critical physical and cyber systems so as to protect the national critical infrastructure. Design/methodology/approach This paper reviews several ICS security assessment methodologies and explores whether the existing methodologies are indeed sufficient to meet the cyber security assessment exercise required to validate the security of electrical power control systems. Findings The study showed that most of the examined methodologies seem to concentrate on vulnerability identification and prioritisation techniques, whilst other security techniques received noticeably less attention. The study also showed that the least attention is devoted to patch management process due to the critical nature of the SCADA system. Additionally, this review portrayed that only two security assessment methodologies exhibited absolute fulfilment of all NERC-CIP security requirements, whilst the others only partially fulfilled the essential requirements. Originality/value This paper presents a review and a comparative analysis of several standard SCADA security assessment methodologies and guidelines published by internationally recognised bodies. In addition, it explores the adequacy of the existing methodologies in meeting cyber security assessment practices required for electrical power networks.

Cyber security and cyber space of Ukraine remained for a long time out of the attention of domestic researchers and, therefore, civil servants. For more than 20 years, the young Ukrainian state did not waste its efforts on the formation of not only effective and reliable troops, but also information security. The government did not endeavored to strengthen the country’s defense, and only weakened its lack of progress in fighting corruption and the dominance of Russian media and intelligence. As a result, in the spring of 2014, after a long confrontation between the regime of Viktor Yanukovych and the citizens of Ukraine, Russia failed to conduct special operations with the aim of annexing the Crimea and facilitate the war in Donbas. Not the least role in this played a raid for information and factors cyber Russian hackers for the purpose of paralyzing government agencies and influence on public opinion in Ukraine through Russian-controlled media. As a result of prolonged and massive cyber attacks, Ukrainian state structures, the banking system, industrial facilities and private business suffered significant material and reputational losses. At the same time in Ukraine began to realize the seriousness of cyber security as a component of national security and contribute to creating cyber police, national cyber security strategy, acceptance of a number of regulations on cyber security, strengthening public defense for the protection of domestic cyber space. At the moment, Ukraine is on the way to rethinking the role of cyber security and the formation of a national system of protection against cyber threats.

AbstractCyber-attacks these threats, the cyber security assessment of IT and OT infrastructures can foster a higher degree of safety and resilience against cyber-attacks. Therefore, the use of attack simulations based on system architecture models is proposed. To reduce the effort of creating new attack graphs for each system under assessment, domain-specific languages (DSLs) can be employed. DSLs codify the common attack logics of the considered domain.Previously, MAL (the Meta Attack Language) was proposed, which serves as a framework to develop DSLs and generate attack graphs for modeled infrastructures. In this article, powerLang as a MAL-based DSL for modeling IT and OT infrastructures in the power domain is proposed. Further, it allows analyzing weaknesses related to known attacks. To comprise powerLang, two existing MAL-based DSL are combined with a new language focusing on industrial control systems (ICS). Finally, this first version of the language was validated against a known cyber-attack.
