Internet of Things Technology in Ecological Security Assessment System of Intelligent Land

In this study, the important city of Guanzhong Plain-Weinan, was studied and its ecological security index changed from the year of 2000 to 2012. The stress-state-response (PSR) model was used to establish an ecological security assessment system based on agricultural development cities. The method of quantitative research including 12 indicators based on the fuzzy analytic hierarchy process (FAHP) model was constructed, and the main aspects such as the natural environment, economic society, and human activities were designed. The results showed that from 2000 to 2012, the area of ecological security and stability is gradually increasing, and the stability of the ecological environment is enhanced. The ecological security level in the central region of the country has developed well in the past 10 years, but the ecological security level in some areas has gradually increased in edge area.

With the accelerated development of urbanization human’s activities are playing an increasing negative impact on ecological security of atmospheric environment especially for urban movement. In order to manage the statement of urban ecological security of air environment as well as its spatial and temporal trends, several measures and methods for resolving the issues are provided in the paper. An assessment system is established with 19 factors and 4 sub-systems based on the atmospheric environment characteristics of Changde through adopting the Pressure-State-Danger-Response (P-S-D-R) model. For guaranteeing the reliability of results two methods are used to determine the weight. The final assessment results indicate that from 2005 to 2009 the composite index for ecological security of atmospheric environment in Changde lies between 0.27-0.87 and the overall trend of quality for ecological security improves gradually which turns to fluctuate between less and more secure and the security threat is not avoided.

The Internet Of Things

This article is about developing a security assessment system for smart homes that use Internet of Things technology. The Internet of Things (IoT) is a nascent paradigm focused on the relationship of things or devices to each other and users. Over time, most connections on the Internet of Things go from «people interact with things» to «things interact with things». This technology is expected to be an important milestone in the development of smart homes to bring convenience and efficiency to our lives and our homes. But the introduction of this IoT technology in our homes will be important for the safety of these technologies. Connecting all smart objects inside the house to the Internet and to each other leads to new security and privacy issues, such as the confidentiality, authenticity, and integrity of the data that is perceived and exchanged. These technologies are very vulnerable to various security attacks that make a smart home based on IoT unsafe to live in, so security risks need to be assessed to assess the situation of smart homes. For any technology to be successful and widely used, it must gain the trust of users, ensuring sufficient security and confidentiality. As in all sectors, maintaining security will be the most important challenge to overcome. As homes become more computerized and filled with devices, potential computer security attacks and their impact on residents need to be investigated. This paper uses a methodology that focuses mainly on information assets and examines containers (technical, physical and human) and conducts security risk assessments to highlight various security vulnerabilities in the smart home based on the Internet of Things, the consequences and proposing measures against identified problems. that meet most safety requirements. Finally, it offers recommendations for users.

And Control

This article presents an analysis of the changes that have occurred in one of the most important state documents - the Food Security Doctrine of the Russian Federation. Criticism of this document can be traced in many scientific works: some experts attribute the Doctrine only to a program document, while others expect it to be implement and control, i.e. much more in practice. An assessment of the significance and essence of such a document as the doctrine as a whole made it possible to determine its place both in the system of public administration and the degree of its significance in the regulatory field. Based on the findings, an attempt was made to analyze changes in the new Doctrine of Food Security of the Russian Federation, approved by Decree of the President of Russia No. 20 of 01.21.2020. Structural changes in the new Doctrine are highlighted, as well as a critical assessment of the features of all its main sections. The greatest changes were revealed in the state food security assessment system, and it was also determined that the new version of the Doctrine has a greater social bias. If there are positive changes, some omissions of the most important areas of agri-food policy have been identified, which, despite their absence or insufficient reflection in the Doctrine, can be presented and decided at the level of subsequent documents, but only if the Doctrine in practice will be a fundamental document of public administration and regulatory framework.
