Research and practice of SASE cloud security by Chaoyang YE, Xin WANG, Shicong ZHANG, Zhiyong ZHAN, Yisha LIU

“…With the development of the Internet today, earth shaking changes have taken place compared with the traditional network.In today's network reform, ＆quot;cloud＆quot; has become the mainstream direction of the evolution of enterprise IT architecture, so the requirements for cloud security are becoming higher and higher.The practical deployment scheme of SASE cloud security architecture was introduced to solve the problem of cloud security for customers.A unique and complete SASE solution was proposed, which combined security functions with SD-WAN functions, and realized real-time monitoring, intelligent analysis and automatic interception of malware or malicious activities by building a unified management and control platform and centralized deployment of core security resource pool.Practice has proved that the scheme achieves the expected results in unified management and control, intrusion detection and defense, fine access control and so on, and can fully ensure the cloud security of enterprises.…”

Synchronous collaborative application of nuclear power engineering design platform by Zhihua ZENG, Delong YI, Yan LI

“…At present,the nuclear power business shows the development trend of multi-route,multi-base develop-ment trend.Coupled with the huge workload of nuclear power engineering design and the fine division of labor cha-racteristics,the relevant professional in different places appears more and more cross-design in the nuclear power en-gineering design,resulting in the frequency of funding becoming more and more dense between the various profes-sional.How to shorten the synchronization time of engineering design data between different places,and even achieve real-time synchronization of engineering design data is worth to study in the field of collaborative design of nuclear power projects.From the point of view of system verification,the existing popular virtualization technology was used to carry out an in-depth exploration and verification on the synergetic synergy of nuclear power engineering design,and a set of auxiliary access platform was added on the basis of the original design platform structure to real-ize remote user access and collaborative design of nuclear power projects.The research results have guiding signific-ance for the follow-up design and production platform upgrade and optimization.…”

The Mechanisms of Guaranteeing the Right to Clean Air in Iran and International Documents by Fatemeh Hamidi, Maryam Afshari, Ali Mashhadi

“…According to the results of the present study, it can be acknowledged that in Iran, as a developing country, the issue of guaranteeing the right to clean air and its implementation mechanisms has not yet found its real place in the legal system. International instruments also lack a specific guarantee of performance such as reciprocity or specific contractual mechanisms. …”
