Abstract:

Automatic classification of devices in computer network can be used for detection of anomalies in a network and also it enables application of security policies per device type. The key to creating a device classifier is a quality data set, the public availability of which is low and the creation of a new data set is difficult. The aim of this work is to create a tool, that will enable automated annotation of the data set of network devices and to create a classifier of network devices that uses only basic data from network flows. The result of this work is a modular tool providing automated annotation of network devices using system ADiCT of Cesnet's association, search engines Shodan and Censys, information from PassiveDNS, TOR, WhoIs, geolocation database and information from blacklists. Based on the annotated data set are created several classifiers that classify network devices according to the services they use. The results of the work not only significantly simplify the process of creating new data sets of network devices, but also show a non-invasive approach to the classification of network devices.

Abstract:

Předkládaná disertační práce je zaměřena na "heterogenní propojení mobilních zařízení v bezdrátových systémech 5. generace". Navzdory nepochybnému pokroku v rámci navržených komunikačních řešení postrádají mobilní sítě nastupující generace dostatečnou šířku pásma a to hlavně kvůli neefektivnímu využívání rádiového spektra. Tato situace tedy v současné době představuje řadu otázek v oblasti výzkumu. Hlavním cílem této disertační práce je proto návrh nových komunikačních mechanismů pro komunikaci mezi zařízeními v bezprostřední blízkosti s asistencí mobilní sítě a dále pak návrh a implementace algoritmů pro dynamické přidělování frekvenčního spektra v nastupujících mobilních sítích 5G. Navrhnuté komunikační mechanismy a algoritmy jsou následně komplexně vyhodnoceny pomocí nově vyvinutých simulačních nástrojů (kalibrovaných s využitím 3GPP trénovacích dat) a zejména pak v experimentální mobilní síti LTE-A, která se nachází v prostorách Vysokého učení technického v Brně, Česká Republika. Získané praktické výsledky, které jsou podpořeny zcela novou matematickou analýzou ve speciálně navržených charakteristických scénářích, představují řešení pro vlastníka spektra v případě požadavků na jeho dynamické sdílení. Tato metoda tedy představuje možnost pro efektivnější využití spektra v rámci mobilních sítí 5G bez degradace kvality služeb (QoS) a kvality zážitků (QoE) pro koncové uživatele. Vědecký přínos dosažených výsledků dokazuje fakt, že některé z principů představených v této disertační práci byly zahrnuty do celosvětově uznávaného standardu (specifikace) 3GPP Release 12.

Abstract:

The diploma thesis describes theory that is needed for application development for acquisition of communication statistical data from network infrastructure devices. Aplication is called SDSKSI. The project compares protocols suitable for this purpose. Finally SNMP protocol was chosen because it is the most common in network devices. SNMP is described in detail. Each SNMP operation has its own practical demonstration. In the project there is also described MIB database and data types of MIB objects. Application is able to create network topology. Then administrator of network can imagine how the network looks like. For each device that support SNMP protocol are periodically collected and stored statistical data which can be exported to the file. For application development were chosen programming languages according to several criteria. Content of the laboratory exercise is presented. At the end of the project there are some system solutions for collecting statistical data. Diploma thesis contents two attachments. The first is containing the full text of laboratory task. The second is DVD disc. Disc is containing ready to boot aplication SDSKSI.

Abstract:

At the beginning, the work describes DNS and SSL/TLS protocols, it mainly deals with communication between devices using these protocols. Then we'll talk about data preprocessing and data cleaning. Furthermore, the thesis deals with basic data mining techniques such as data classification, association rules, information retrieval, regression analysis and cluster analysis. The next chapter we can read something about how to identify mobile devices on the network. We will evaluate data sets that contain collected data from communication between the above mentioned protocols, which will be used in the practical part. After that, we finally get to the design of a system for analyzing network communication data. We will describe the libraries, which we used and the entire system implementation. We will perform a large number of experiments, which we will finally evaluate.

Abstract:

There is a family of COMBO cards used for netork monitoring acceleration being developed on the Liberouter project, which is the CESNET's research activity. These cards are equipped with Xilinx's programmable field array. To enable usage of classic tools for network monitoring and management, not only application specific tools, it is necessary to implement network interface card on the platform, that realizes packet reception and transmission through the standard Linux kernel interface. This thesis describes the design and implementation of network interface card's key components. Those are DMA controller and Linux device driver.

Abstract:

This masters thesis describes simulation of network using Network Simulator. Model of network and description of simulation is extracted from the analysis of configuration files of active network devices, and translated by a parser. Concept and implementation of the parser is described here. Because IPv4 addressing is not supported in Network Simulator, it was added as a new module. The Network Simulator is also extended by filtering properties of packets using access control lists. Practical usage of the implemented modules is demonstrated on a simulation of real network.

Abstract:

his semestral´s thesis deals with proposal and system implementation for automatic configuration of Cisco network devices. This system is called AutoConf and it is intended for distant copying configuration files from eagle-server to the switches and routers in Cisco academy laboratory. It is handled by web pages placed on eagle-server. In this system, user can create new laboratory exercises with configuration files for network devices and then these files could be used for configurations. Informations about done configurations are saved in relation database MySQL. Network devices which will be configured by system AutoConf have to be connected with eagle-server. To setup their connection settings was created decision-making mechanism. If it detects physical connection between network device and eagle-server before network device starts, it will set network device for communication with eagle-server.
