Implementation and Design of IoT Based as a File Server Storage With Raspberry Pi 3b + Using Open Media Vault

In general, the use of IoT (Internet of Things) is still not felt, one of which is the use of IoT which can be used as a file server or storage media. Therefore, we need a storage media that is cheap, simple, efficient, does not require a large space and requires relatively fast time in designing and configuring storage media. To overcome the above problems how to build, design, create, process and utilize unused goods around so that they can become useful goods and don’t require excessive costs so as to create a service that can be used and developed in a sustainable manner. After receiving information that there is a computer that is cheap, simple, and without taking up a lot of space called the Raspberry Pi. From the background of the problem above, using the Advanced RISC Machine (ARM) architecture based on System on Chip (SoC), using Linux Open Media Vault.

A Dockers Storage Performance Evaluation: Impact of Backing File Systems

This paper reports on an in-depth examination of the impact of the backing filesystems to Docker performance in the context of Linux container-based virtualization. The experimental design was a 3x3x4 arrangement, i.e., we considered three different numbers of Docker containers, three filesystems (Ext4, XFS and Btrfs), and four application workloads related to Web server I/O activity, e-mail server I/O activity, file server I/O activity and random file access I/O activity, respectively. The experimental results indicate that Ext4 is the most optimal filesystem, among the considered filesystems, for the considered experimental settings. In addition, the XFS filesystem is not suitable for workloads that are dominated by synchronous random write components (e.g., characteristical for mail workload), while the Btrfs filesystem is not suitable for workloads dominated by random write and sequential write components (e.g., file server workload).

Network File System Implementation on Computer-Based Exam

In the world of education, exam is the final stage to evaluate the student abil-ity. The length of the correction process and the expensive cost of printing for manually exams are obstacles that often occurs when administering the ex-ams. Computer-based exams is an effort that is present to solve the problems, by using a computer, then the cost of printing documents and others can be minimized, besides that there is no need for manually correction time, be-cause when students finished the exam, the student's grades can be immedi-ately known. So many advantages are offered by computer-based exams but of course there are still problems that arise. The most common thing is the slow server in processing requests from clients when accessed together, in-creasing the number of servers using Network File Server is one of the efforts to correct the shortcomings of computer-based exams. Using Network File Server is expected to be able to overcome these problems.

Epiviz File Server: Query, transform and interactively explore data from indexed genomic files

Motivation Genomic data repositories like The Cancer Genome Atlas, Encyclopedia of DNA Elements, Bioconductor’s AnnotationHub and ExperimentHub etc., provide public access to large amounts of genomic data as flat files. Researchers often download a subset of data files from these repositories to perform exploratory data analysis. We developed Epiviz File Server, a Python library that implements an in situ data query system for local or remotely hosted indexed genomic files, not only for visualization but also data transformation. The File Server library decouples data retrieval and transformation from specific visualization and analysis tools and provides an abstract interface to define computations independent of the location, format or structure of the file. We demonstrate the File Server in two use cases: (i) integration with Galaxy workflows and (ii) using Epiviz to create a custom genome browser from the Epigenome Roadmap dataset. Availability and implementation Epiviz File Server is open source and is available on GitHub at http://github.com/epiviz/epivizFileServer. The documentation for the File Server library is available at http://epivizfileserver.rtfd.io.

Improvement of the Regulatory Framework of Information Security for Terminal Access Devices of the State Information System

The aim of the study is to increase the effectiveness of information security management for state information systems (SIS) with terminal access devices by improving regulatory legal acts that should be logically interconnected and not contradict each other, as well as use a single professional thesaurus that allows understanding and describe information security processes.Currently, state information systems with terminal access devices are used to ensure the realization of the legitimate interests of citizens in information interaction with public authorities [1].One of the types of such systems are public systems [2]. They are designed to provide electronic services to citizens, such as paying taxes, obtaining certificates, filing of applications and other information. The processed personal data may belong to special, biometric, publicly available and other categories [3]. Various categories of personal data, concentrated in a large volume about a large number of citizens, can lead to significant damage as a result of their leakage, which means that this creates information risks.There are several basic types of architectures of state information systems: systems based on the “thin clientpeer-to-peer network systems; file server systems; data processing centers; systems with remote user access; the use of different types of operating systems (heterogeneity of the environment); use of applications independent of operating systems; use of dedicated communication channels [4]. Such diversity and heterogeneity of state information systems, on the one hand, and the need for high-quality state regulation in the field of information security in these systems, on the other hand, require the study and development of legal acts that take into account primarily the features of systems that have a typical modern architecture of “thin customer". Materials and research methods. The protection of the state information system is regulated by a large number of legal acts that are constantly being improved with changes and additions to the content. At the substantive level, it includes many stages, such as the formation of SIS requirements, the development of a security system, its implementation, and certification. The protected information is processed in order to enforce the law and ensure the functioning of the authorities. The need to protect confidential information is determined by the legislation of the Russian Federation [5, 6]. Therefore, to assess the quality of the regulatory framework of information security for terminal access devices of the state information system, the analysis of the main regulatory legal acts is carried out and on the basis of it, proposals are developed by analogy to improve existing regulatory documents in the field of information security.Results. The paper has developed proposals for improving the regulatory framework of information security for terminal access devices of the state information system- for uniformity and unification, the terms with corresponding definitions are justified for their establishment in the documents of the Federal Service for Technical and Export Control (FSTEC) or Rosstandart;- rules for the formation of requirements for terminals, which should be equivalent requirements for computer equipment in the “Concept for the protection of computer equipment and automated systems from unauthorized access to information ".Conclusion. General recommendations on information protection in state information systems using the “thin client" architecture are proposed, specific threats that are absent in the FSTEC threat bank are justified, and directions for further information security for the class of state information systems under consideration are identified. Due to the large number of stakeholders involved in the coordination and development of unified solutions, a more specific consideration of the problems and issues raised is possible only with the participation of representatives of authorized federal executive bodies and business representatives for discussion.
