A Heterogeneous Parallel Processing System Based on Virtual Multi-Bus Connection Network

Hajder Piotr, Rauch Łukasz, Nycz Mariusz, Hajder Mirosław

Annals of Computer Science and Information Systems

2019

Vol. 19

9--17

This work presents organization, architecture and synthesis as well as analysis of the reconfigurable heterogeneous parallel processing system. Reconfiguration takes place on two levels of the connection network: physical and logical. For its implementation, passive multi-channel optical networks were used. Due to its dynamic nature, the system is designed to handle computational and communication load of an explosive nature and is addressed in the first place to the production sphere of economy. The dynamically combined connection network not only prevents traffic bursts, but also based on the physical and logical circuit commutation gives the possibility of adapting to the existing traffic pattern. Although the described solution is addressed to the optical transmission environment, its effective functioning in the Ethernet networks with circuit switching and partly in wireless networks has been confirmed empirically. The theoretical foundations were verified in the design and construction of a reconfigurable super-microcomputer and the intelligent system detection of attacks addressed to industrial Internet.

Analiza podatności na ataki socjotechniczne w jednostce samorządu terytorialnego

Nycz Mariusz, Michno Bartosz, Mlicki Rafał

Zeszyty Naukowe WSEI. Seria Transport i Informatyka

2014

T. 4, nr 1

5--10

Celem tej analizy było sprawdzenie podatności na ataki socjotechniczne w lokalnej siedzibie samorządu terytorialnego. W tym celu została opracowana ankieta, w których poruszono problemy bezpieczeństwa informacji na poziomie zarówno podstawowym jak i bardziej rozbudowanym. Ankietowani odpowiadali na około 20 pytań. Wyniki ankiety dały podstawy do zbudowania przybliżonych profili ankietowanych wraz z poziomem ich podatności na określone zagrożenia socjotechniczne, m. in. w Internecie. Ze względów bezpieczeństwa ankieta oraz jej bezpośrednie wyniki nie będą ujawniane.

The purpose of the analysis was to check the vulnerability to social engineering attacks in a local government unit in Poland. To that end, a survey was designed where security of information issues were raised on both basic and advanced levels. Interviewees were answering to about 20 questions. On the basis of the results, approximate profiles of interviewees were created and as well as vulnerability levels to certain social engineering attacks were determined. For security reasons, the questions and the results of the survey will not be published.
