scholarly journals Saudi Arabia National Cyber Security System: Specificity and Development Risks

The research featured the national cybersecurity system of the Kingdom of Saudi Arabia. The cybersecurity standards developed by the International Telecommunication Union of the United Nations made it possible to reveal the institutional and legal foundations of the digital security system, as well as the degree of involvement in international cybersecurity cooperation. The analysis demonstrated the key risks of the development of the Saudi cyber model. The assessment by the International Telecommunication Union standards gave quite positive results. However, Saudi Arabia proved to adhere to a catching-up development model and still experiences some problems with national cyberspace security. Some are of global nature, e.g. legislation gaps, while others result from the specifics of the national model of state governance. The most obvious risks include the imbalance between the civil and military sectors, the disagreements between various regions, and the poor integration of the local hacker community into the overall structure of national cybersecurity. Saudi Arabia plans to eliminate these imbalances in the medium term in order to build an integrated cybersecurity system by expanding its international cooperation.

During the last decade, Machine Learning (ML) has increasingly become a hot topic in the field of Computer Networks and is expected to be gradually adopted for a plethora of control, monitoring and management tasks in real-world deployments. This poses the need to count on new generations of students, researchers and practitioners with a solid background in ML applied to networks. During 2020, the International Telecommunication Union (ITU) has organized the "ITU AI/ML in 5G challenge", an open global competition that has introduced to a broad audience some of the current main challenges in ML for networks. This large-scale initiative has gathered 23 different challenges proposed by network operators, equipment manufacturers and academia, and has attracted a total of 1300+ participants from 60+ countries. This paper narrates our experience organizing one of the proposed challenges: the "Graph Neural Networking Challenge 2020". We describe the problem presented to participants, the tools and resources provided, some organization aspects and participation statistics, an outline of the top-3 awarded solutions, and a summary with some lessons learned during all this journey. As a result, this challenge leaves a curated set of educational resources openly available to anyone interested in the topic.

AbstractThis paper documents a simple parametric polynomial line-of-sight channel model for 100–450 GHz band. The band comprises two popular beyond fifth generation (B5G) frequency bands, namely, the D band (110–170 GHz) and the low-THz band (around 275–325 GHz). The main focus herein is to derive a simple, compact, and accurate molecular absorption loss model for the 100–450 GHz band. The derived model relies on simple absorption line shape functions that are fitted to the actual response given by complex but exact database approach. The model is also reducible for particular sub-bands within the full range of 100–450 GHz, further simplifying the absorption loss estimate. The proposed model is shown to be very accurate by benchmarking it against the exact response and the similar models given by International Telecommunication Union Radio Communication Sector. The loss is shown to be within ±2 dBs from the exact response for one kilometer link in highly humid environment. Therefore, its accuracy is even much better in the case of usually considered shorter range future B5G wireless systems.

The arrival of information and communication technologies is nothing new. The number of people using these technologies and moving in cyberspace is growing, and therefore it is an important role of the state to respond sufficiently to such developments. A fundamental role of the state is to create a stable security system consisting of complex legislation as well as creation of a legislative environment capable of responding flexibly to the growing number of diverse incidents in cyberspace. Sufficient legal regulation consisting of unambiguous determination of competencies and tasks of individual subjects represents the basic pillar for the creation of a stable security system. The role of the state is also to maintain existing and create new partnerships with organizations that are able to provide relevant information and knowledge in the field of cyber security.

To grasp Complex characteristics of shortwave (HF) channel is the key and difficulty to research HF communication. On the premise of comprehending the ionosphere prediction method in the Asia Oceania region, HF frequency prediction method recommended by the International Telecommunication Union (ITU) is improved in this paper, and the engineering calculation method of predicting HF frequency in the Asia Oceania region is concluded and summarized. Comparing with the ITS (the Institute for Telecommunication Science) software’s predicting result, the method is improved to some extent in time availability and SNR in the receiving point.
