  Abstract ▼

  Wireless data transmission networks generate threats that cannot be protected against by means
  traditional for wired networks, because in this case it is impossible to provide equivalent security of wired
  networks due to the physical properties of the communication channel. The purpose of the article is to
  determine the actual problems that exist in ensuring information security (IS) in wireless segments of data
  networks. To achieve this goal, a selection of threats potentially realizable in wireless networks has been
  made from the information security threat bank of FSTEC of Russia. It is established that the realization of
  such threats can lead to a full set of violations of the state of IS, namely: violation of confidentiality, integrity
  and availability of information. The existing practical ways of providing IS in wireless segments of
  networks are considered. The analysis of these methods pointed out the technical possibility of creating an
  additional boundary in the system of echeloned information protection. In turn, this provides the potential
  to detect vulnerabilities and intrusions at the link layer of network communication both in local networks
  of enterprises and in large-scale public networks. In accordance with the goal, aspects of building such a
  defense frontier are grouped, related to control of the link layer of network interaction of wireless devices,
  reduction of frequency-territorial clusters and legal support. The review of publications reveals a gap
  between the existing approaches to radio monitoring and IS provision, and also reveals poor development
  of the direction related to research in the field of detection and prevention of wireless intrusions. The obtained
  result indicates the need to revise the existing concept of radio monitoring and develop appropriate
  organizational and technical measures for its integration into the system of measures to ensure IS, which
  should help to solve the problem of timely detection and prevention of intrusions into wireless segments of
  data networks, as well as the identification of vulnerable elements of the infrastructure of these networks.

  Abstract ▼

  The applied programs and cad for cutting various materials are effective in conditions of
  single and multi-item small-scale production using the group method of cutting into blanks of arbitrary
  geometric shape. When cutting sheet and rolled metal products in large-scale and mass production,
  characterized by individual cutting into blanks of the same name, the created programs
  have limited use. For automated cutting in such production conditions, it is necessary to adapt
  existing systems and programs or create new ones using modern approaches and a new cutting
  design scheme based on the use of a new cutting efficiency indicator with minimizing the cost of
  manufactured products, conducting calculations for parts of the same group (by brand and thickness),
  which will allow rational selection of waste for other parts of this group. To solve the problem,
  a new model for optimizing guillotine cutting with minimizing metal costs and reducing the
  cost of cutting products is proposed and discussed in the article. To implement automated cutting
  design depending on the new resource-saving coefficient (RSC) and manage information about
  detailed cutting of metal in the course of the research conducted by the authors, the database
  «Cluster of parts «PROM-2013»» and the program «PROM-2013» were developed, allowing
  assessing the efficiency of cutting according to RSC and choosing the best option. Using the example
  of the «side panel» part, the effectiveness of the developed algorithm and the stages of automated
  design of optimal cutting based on the RSC indicator with the formation of output documents
  «material cutting cards» are shown
