A Security Enhancement Model Based on Switching Edge Strategy in Interdependent Heterogeneous Cyber-Physical Systems

With the advent of cross-domain interconnection,large-scale sensor network systems such as smart grids,smart homes,and intelligent transportation have emerged.These complex network systems often have a CPS(Cyber-Physical System)architecture and are usually composed of multiple interdependent systems.Minimal faults between interdependent networks may cause serious cascading failures between the entire system.Therefore,in this paper,we will explore the robustness detection schemes for interdependent networks.Firstly,by calculating the largest giant connected component in the entire system,the security of interdependent network systems under different attack models is analyzed.Secondly,a comparative analysis of the cascade failure mechanism between interdependent networks under the edge enhancement strategy is carried out.Finally,the simulation results verify the impact of system reliability under different handover edge strategies and show how to choose a better handover strategy to enhance its robustness.The further research work in this paper can also help design how to reduce the interdependence between systems,thereby further optimizing the interdependent network system’s structure to provide practical support for reducing the cascading failures.In the later work,we hope to explore our proposed strategies in the network model of real-world or close to real networks.

Japan-UK Security Cooperation in the Context of the Convergence of the Indo-Pacific Strategy and Global Britain

Japan-UK security cooperation has been deepening as the Indo-Pacific Strategy has converged with Global Britain,which has become strongly Indo-Pacific-oriented.In terms of their cooperation on security,the two countries have close security interactions,high-level security consultations,numerous mechanisms on security cooperation,frequent defense cooperation and exchanges between forces,and cooperation geared at a response to the Korean nuclear issue.In particular,Japan and the UK regard Indo-Pacific security as the strategic focus of their cooperation,and this underscores the rules-based international order.There are multiple motivations for Japan and the UK to strengthen their security cooperation,and the deepening of their security cooperation in the Indo-Pacific region is to a great extent due to strategic factors,including responding to the US strategic adjustment,Japan and Britain’s respective proactive strategic demands,the improving strategic positions of the Indopacific region,their seeking to shape the regional order in the Indo-Pacific,and so on.Despite facing challenges,Japan-UK security cooperation is continuously strengthening against a background of deepening strategic convergence between the two countries and great power competition.

Investment strategy analysis of information system security in consideration of attackers

In order to solve the problem of howa firm makes an optimal choice in developing information systems when faced with the following three modes: development by its own efforts, outsourcing them to a managed security service provider( MSSP) and cooperating with the MSSP, the firm 's optimal investment strategies are discussed by modeling and analyzing the maximum expected utility in the above cases under the condition that the firm plays games with an attacker.The results showthat the best choice for a firm is determined by the reasonable range of the cooperative development coefficient and applicable conditions. When the cooperative development coefficient is large, it is more rational for the firm to cooperate with the MSSP to develop the information system. When the cooperative development coefficient is small, it is more rational for the firm to develop the information system by its own efforts. It also shows that the attacker's maximum expected utility increases with the increase in the attacker 's breach probability and cost coefficient when the cooperative development coefficient is small. On the contrary, it decreases when the cooperative development coefficient is large.

A fault injection model-oriented testing strategy for component security

A fault injection model-oriented testing strategy was proposed for detecting component vulnerabilities.A fault injection model was defined,and the faults were injected into the tested component based on the fault injection model to trigger security exceptions.The testing process could be recorded by the monitoring mechanism of the strategy,and the monitoring information was written into the security log.The component vulnerabilities could be detected by the detecting algorithm through analyzing the security log.Lastly,some experiments were done in an integration testing platform to verify the applicability of the strategy.The experimental results show that the strategy is effective and operable.The detecting rate is more than 90%for vulnerability components.

Evolution and impacts of the United States’Arctic strategy and China’s responses

On 7 October,2022,the Biden administration released an updated version of the National Strategy for the Arctic Region based on new developments in the Arctic region and global affairs.This strategy emphasizes traditional security issues in the Arctic,attaches great importance to climate governance in the region,and advocates for restoring American leadership through international cooperation.In view of the strong influence of the United States(U.S.)in the Arctic region,the changes of the U.S.Arctic strategy will inevitably have an impact on China’s scientific researchrights,economic interests,and governance rights in the Arctic region.To respond to the new situation brought about by the changes in the U.S.Arctic strategy,China should take the initiative to maintain positive relationships with all Arctic countries,and continue its active participation in Arctic affairs.

The Security Strategy of the European Union: Origin, Evolution, and Policy Direction

With the deepening development of European integration and the change of international situation, member states of the European Union(EU) have gradually strengthened consultation and coordination in the field of security and established corresponding mechanisms. In this process,the EU has also formed and developed its National Security Strategy and issued four versions of security strategy reports in 2003, 2008, 2016, and 2022. The 2022 version of the EU security strategy(hereafter referred to as the New Security Strategy), for the first time, has identified Russia as a long-term and direct threat. Furthermore, it has paid increased attention to traditional security, especially the upgrading of military capabilities and has become more reliant on the United States and the North Atlantic Treaty Organization. In the future, the EU will accelerate the militarization process, exert all-out efforts to contain Russia, scrutinize neighborhood security, and increase its swing on China policy.

India’s National Security Strategy:Pursuits,Origins,and Practice

India has upheld extremely rich practices of national security since its founding as a republic because of its unique geo-environmental features, historical legacies, and traditional cultures, which reflect a type of national security strategy that has distinct Indian characteristics. Generally, successive governments in India have followed the basic principles articulated in Kautilya’s Arthasastra and various security practices adopted during the British Raj. India’s national security strategies are based on an internal logic of geopolitical rivalry and changes in international scenarios, and they are strongly influenced by Hindu traditions and the “Sad-Dharma” purported by King Ashoka. The objective is to create an India-dominated security order in the South Asian subcontinent, which persistently builds its capacity and system as a “net security provider” in the Indian Ocean Rim. Moreover, India is vigorously expanding its network of influence in the Pacific region in an effort to become a world leading power that enjoys a high level of strategic autonomy.

Strategic Direction of Russia Interpreted from Its New National Security Strategy

In July 2021,Russia unveiled its new National Security Strategy,which is a considerably updated version compared with the previous one and hence presents several new features.For instance,it further stresses that security should be prioritized over other aspects;it gives more attention to the chaotic aspects of order change in its assessment of the international situation;it highlights the threats from the West;and it places increased emphasis on domestic capacity building as a means for safeguarding national security.From the content of the new Strategy as well as Russia’s policies in recent years,the strategy of Russia for the foreseeable future can be generally characterized as inward-looking.Domestically,its policies will become more conservative;diplomatically,it will take up a defensive position;and economically,it will increasingly emphasize security and selfreliance.In other words,several issues that were previously overlooked will be given attention.However,strategic introversion does not mean that Russia will invest all its energy in defense.Instead,Russia will build up strength for changes that lie ahead.With the expected strategic introversion,Russia will fnd difculty in making breakthroughs in terms of its relations with the West;the China-Russia relations will continue on the path of steady development;and Russia will place greater importance to the balance of power among major countries.
