Operational concepts of HVDC in the context of security assessment in the German transmission grid

Because of the realization of HVDC connections parallel to the synchronous grid in Germany, operational concepts become more important in the context of system security aspects. In this article commonly known concepts are analyzed regarding their suitability for the German transmission system. Therefore, an approach for the analysis was developed and exemplary results are given using this approach. Under consideration of the overall system, the concepts of reducing losses in combination with minimizing(n-1)-warnings or-indications^1 as well as the sole minimization of(n-1)-warnings and-indications are the most reasonable approaches. However, under grid security aspects best results can be achieved by reducing operational limits and therefore, by the minimization of(n-1)-warnings.

Concept Drift Analysis and Malware Attack Detection System Using Secure Adaptive Windowing

Concept drift is a main security issue that has to be resolved since it presents a significant barrier to the deployment of machine learning(ML)models.Due to attackers’(and/or benign equivalents’)dynamic behavior changes,testing data distribution frequently diverges from original training data over time,resulting in substantial model failures.Due to their dispersed and dynamic nature,distributed denial-of-service attacks pose a danger to cybersecurity,resulting in attacks with serious consequences for users and businesses.This paper proposes a novel design for concept drift analysis and detection of malware attacks like Distributed Denial of Service(DDOS)in the network.The goal of this architecture combination is to accurately represent data and create an effective cyber security prediction agent.The intrusion detection system and concept drift of the network has been analyzed using secure adaptive windowing with website data authentication protocol(SAW_WDA).The network has been analyzed by authentication protocol to avoid malware attacks.The data of network users will be collected and classified using multilayer perceptron gradient decision tree(MLPGDT)classifiers.Based on the classification output,the decision for the detection of attackers and authorized users will be identified.The experimental results show output based on intrusion detection and concept drift analysis systems in terms of throughput,end-end delay,network security,network concept drift,and results based on classification with regard to accuracy,memory,and precision and F-1 score.

What Kind of Security Concept Does Our World Need?

While the threat of war has decreased, there have appeared intricate security issues that affect all aspects of human life, breaking through various defenses and threatening the well being of all actors in the contemporary world, including nations, groups and individuals. This risky situation calls for a new security concept, one that transcends traditional state centrism, national supremacy and coercion. The new security concept, which should assimilate the general theory of grand strategy,focuses on a vision that spans time and space, valuing humankind as it exists as one of the dynamic factors of nature and society. The essentials of the new security concept are to recognize balanced development as the substance of security and to govern national strength and the application of means and tactics. It aims at realizing comprehensive security across various social fields within states, to achieve mutual security among national, international and individual actors, as well as harmony between man and nature, continuous security leading to lasting and universal peace in the future.

Security Aspects of Gated Community Housing and the Concept of Safe Townships

Crime is often associated with urban development as urban areas tend to be at greater risk security-wise as compared with other areas. This is the reality of an increasing population crowding into the cities, and fomenting crime in the process. The physical design of the environment also contributes to the escalating crime rate, resulting in fear and anxiety among the residents. The ＂Safe Township＂ concept is an approach to resolving the issue of security in urban areas. It is an agenda within the concept of liveable cities that focuses principally on the problems of urban security. The development of properties within the concept of Gated Community housing is considered a step towards protecting residents in a residential area. The development of fenced Gated Community housing equipped with full-time security facilities is among the strategies in implementing the concept of the Safe Township. This paper discusses the security features in the Gated Community housing development as measures to combat crime in line with the implementation of the Safe Township concept. This study adopts an investigative methodology that combines theory with case studies. The compilation of data was made through literature search, interviews with representatives from the Town Planning Department and data were also collected through observations of Gated Community housing schemes in Johor Bahru.

德国综合安全观:理论缘起、历史演进与实践评估

德国首份《国家安全战略》以“综合安全”为要义,具有理论逻辑和历史脉络可循。德国综合安全观兴起于冷战后,其内在逻辑是对欧洲主义安全观的继承性发展,聚焦两极秩序瓦解后的经济与社会秩序稳定以及应对域外冲突,注重非传统安全,安全参与者包含国家与非国家行为体。克里米亚危机后,传统军事威胁回归欧陆,德国综合安全观“防御性”与“韧性”融合并重。俄乌冲突冲击欧洲安全秩序,德国综合安全观愈发重视国家与联盟防御,并通过“多元化”与“联盟政治”等手段推进“去风险”策略,增强经济与社会韧性,同时也呈现出泛安全化、价值观化与权力政治的特质,其影响力辐射至“印太”地区与对华政策上。然而,德国综合安全政策实践仍面临诸多挑战。防御上,德国提升国防的政治承诺与其军事资源尚不匹配。韧性上,德国“去风险”策略受国际权力对比变化、中国市场红利、德国政界与商界意见的异质性以及德国国内经济成本的制约。为此,中国应客观看待德国安全政策转型的影响。

粮食安全概念、评价体系与地理学优先研究主题

本研究综述了粮食安全概念的演变过程与特征,分析了近年来主要的粮食安全评价指标及未来情景研究方法的优缺点,探讨了地理学在粮食安全系统中可能的作用与研究方向。主要结论为:①粮食安全概念已发展成为包含4个维度、5个尺度的综合概念,宜采用“食物安全系统”词语表征。②家庭尺度与国家尺度是粮食安全评价的重点,粮食安全概念关注重点也从宏观国家角度向微观家庭和个人尺度转变,家庭成员的膳食营养摄入指标成为测度粮食安全的关键要素。③目前粮食安全评价指标体系尚不完善,多数指标均存在定量化不足、标准不统一难以对比、数据不准确等问题;而且未有能涵盖4个维度的全球标准化评价指标体系。④不同研究对粮食安全的未来情景预测结果差别迥异,准确性难以测度。⑤地理学可在食物供给影响机制研究、食物供应链、粮食安全评价指标体系、应对策略等方面做出重要贡献。

人类遗传资源安全的刑法全面性保护

为贯彻落实总体国家安全观,并回应人类遗传资源安全管理的规范发展要求,《刑法修正案(十一)》专门增设第三百三十四条之一,但却仍不足以全面保障人类遗传资源安全。究其原因,一是未规定单位犯罪,二是未全面规制非法提供和买卖人类遗传资源的行为,三是未同等保护人类遗传资源材料和人类遗传资源信息。在总体国家安全观的背景下,涉及人类遗传资源的前置法规制体系日趋完善。刑法全面保护人类遗传资源安全的关键,在于填补非法采集人类遗传资源、走私人类遗传资源材料罪的规范漏洞,合理解释关联罪名则是当下最优解。具体而言,把人类遗传资源信息解释为公民个人信息中的生物识别信息,并将侵犯人类遗传资源安全的行为解释为出售、提供或以其他方法非法获取公民个人信息,从而借助侵犯公民个人信息罪,全面评价自然人或者单位实施的非法采集、非法提供、买卖人类遗传资源材料、人类遗传资源信息的行为。

新粮食安全观下粮食产业支持政策的演化特征与优化构想

新粮食安全观是以人民为中心的共同价值观,确保国家粮食产业安全是新粮食安全观的核心要义、理论意涵和实践方法。新粮食安全观导向下粮食产业具有典型的个性演化规律特征,决定着粮食产业支持政策演化逻辑的特殊性。当前我国粮食产业支持政策具有配置性、再生性、激励性、补偿性、进阶性等五维特征,符合新粮食安全观价值匹配要求,发挥着“牢牢端稳中国饭碗”保障的积极作用。但是,当今国际粮食产业安全的自然风险、社会风险和政治风险剧增,中国式现代化战略任务紧迫而又艰巨,粮食产业支持政策需要与时俱进并持续优化,即要遵循新粮食安全观下粮食产业演化规律,从粮食产业支持政策的静态性系统供给、动态性行为响应、适配性行为协调等方面加强优化设计,推动粮食产业高阶化演进,以适应中国式现代化粮食产业安全响应行为需要,确保中国人的饭碗任何时候都牢牢端在自己手中。

总体国家安全观视域下我国数据安全的主体权责研究

总体国家安全观是维护和塑造中国特色国家安全的最新行动指南,推动建设国家安全制度体系,又为数据安全治理指引了新方向。数据安全是国家安全的重要组成部分,同时又是数据治理的基本价值遵循。近年来,各种数据法律接连颁布,为我国数据安全治理工作夯实了法律基础,同时也在立法层面确定了有公有私、由内而外、权责统一的数据安全治理主体体系。目前我国正处于数据安全治理迭代更新的关键时期,面临数据治理主体不清、相关权责模糊等挑战。我国应当把握总体国家安全观的核心思想,主体层面强化数据安全治理的顶层设计,合理谋划数据治理战略布局,调整并细化数据安全的主体框架及其权责分配,建立因应时代要求的“政府—企业”双边协同的数据安全治理模式。内容层面,一方面应补白、补全、补强我国个人数据权利规则体系,提升公众个人数据安全意识和保护水平;另一方面应建立标准化、严格化、类型化的数据安全保护义务制度,优化数据行业安全保障能力,为数据安全治理营造良好的生态环境。
