Micro-segmentation of local networks is an important element of network security. The main goal of micro-segmentation of network is to reduce a risk of compromising hosts during a cyber-attack. In micro-segmented networks, if one of the hosts has been compromised, the malicious code or attacker will be limited in the "horizontal" actions by the micro-segment to which the compromised host belongs. Existing methods of micro-segmentation of networks have operational drawbacks that impede their effective practical application. This article presents a new method of micro-segmentation of local wired and wireless networks based on downloadable and wireless access control lists, which allows to achieve a high level of granularity of network access policies by minimizing the microsegment, along with high operational characteristics.

This chapter discusses the integration of access control in the development process of hypermedia applications. Two key ideas are proposed: the use of high level, abstract access control models and the inclusion of access control in the whole life cycle of hypermedia applications. Authors present an access control model for hypermedia that makes it possible to formalize access policies using elements of the hypermedia domain, those used to specify structure and navigation services. Abstract models are not enoughto assist developers in dealing with security in a systematic way. Thus, authors describe how high-level access rules can be specified following the Ariadne Development Method (ADM). The ARCE project is used as example of development.

Enterprise network managers need to control the access to their network resources and protect them from malicious users. Current Network Access Control (NAC) solutions rely on approaches, such as firewalls, VLAN, ACL, and LDAP that are inflexible and require per-device and vendor-specific configurations, being error-prone. Besides, misconfigurations may result in vulnerabilities that could compromise the overall network security. Managing security policies involve dealing with many access control rules, conflicting policies, rule priorities, right delegation, dynamics of the network, etc. This work presents HACFlow, a novel, autonomic, and policy-based framework for access control management in OpenFlow networks. HACFlow simplifies and automates the network management allowing network operators to govern rights of network entities by defining dynamic, fine-grained, and high-level access control policies. We analyzed the performance of HACFlow and compared it against related approaches.

Introduction. The paper presents survey results on the awareness towards and practice of Open Access scholarly publishing among Russian academics.Materials and Methods. We employed methods of statistical analysis of survey results. Materials comprise results of data processing of Russian survey conducted in 2018 and published results of the latest international surveys. The survey comprised 1383 respondents from 182 organizations. We performed comparative studies of the responses from academics and research institutions as well as different research areas. The study compares results obtained in Russia with the recently published results of surveys conducted in the United Kingdom and Europe.Results. Our findings show that 95% of Russian respondents support open access, 94% agree to post their publications in open repositories and 75% have experience in open access publishing. We did not find any difference in the awareness and attitude towards open access among seven reference groups. Our analysis revealed the difference in the structure of open access publications of the authors from universities and research institutes. Discussion andConclusions. Results reveal a high level of awareness and support to open access and succeful practice in the open access publications in the Russian scholarly community. The results for Russia demonstrate close similarity with the results of the UK academics. The governmental open access policies and programs would foster the practical realization of the open access in Russia.
