Web Portal for Network Traffic Reporting
Lízal, Miroslav ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This thesis focuses on development of a web portal, which provides information about network traffic. It describes available technologies, which can be used for the network monitoring. It puts emphasis especially on NeTFlow. This paper also descirebs the whole development cycle from analysis to implementation and testing. The outcome of this work is a online system, based on PHP language and PostgreSQL database, which creates reports on the network traffic and makes them accessible via WWW. It is also able to save these reports to a PDF file.

Profiling of Network Traffic for DDoS Mitigation
Ligocká, Alexandra ; Tisovčík, Peter (referee) ; Žádník, Martin (advisor)
The aim of this work is to propose metrics for \gls{ddos} attacks detection and setting the thresholds of normal network traffic in a given computer network at different levels of detail. Based on the selected metrics and network flow data, a network profile is extracted and afterwards stored in memory. Within the implementation part, this work deals with the implementation of program for the collection and calculation of specified metrics, their processing, storage and provides a simple interface providing access to stored data.

GridEngine Reporting Tool
Rožek, František ; Chalupníček, Kamil (referee) ; Kašpárek, Tomáš (advisor)
The aim of this work is to build a tool that will reflect the utilization of the computing cluster, built on Grid Engine technology. Data are processed using PHP and Shell scripts and then stored in MySQL, or RRD databases. The work created a system that handles huge amounts of data and provides a comprehensive view on the utilization of the entire cluster, but also its specific components, or statistics of individual users. Created solution provides current and long-term data. The result of this work allows you to watch computing cluster from a single tool, which was not possible before.

Detection of Volumetric DoS and DDoS Attacks in Real Time on the L3 Network Layer
Škápik, Anton ; Grégr, Matěj (referee) ; Holkovič, Martin (advisor)
This bachelor thesis explores and implements capabilities of real-time DoS and DDoS detection. Leveraging NetFlow stream processing tool, the resulting product provides the ability to detect attacks within a few seconds and create rules to mitigate the attack. The rules are converted from an form of records into a flowspec filter that is distributed by BGP between the routers in the monitored network. The program was implemented and tested. The work is written in collaboration with Flowmon Networks a.s., using their proprietary applications for NetFlow record processing.

Server monitoring component
Boček, Jaromír ; Heriban, Pavel (referee) ; Roupec, Jan (advisor)
This Bachelor thesis deals with the development of a universal server monitoring component for collecting data from various servers. This component meets the requirements for easy installation, setup and activation of the specified server. The monitored unit releases information that the monitored server is active and completely functioning, in particular, information on CPU utilization, state of disk utilization, and state of all logged users. The presented multiplatform concept puts emphasis on the most common platforms, such as Linux and Windows. In addition, transfer of acquired data through the Internet obstacles in the form of firewall configurations and other security technologies has been solved within this work.

Web Portal for Network and Application Response Time Monitoring
Hornický, Pavol ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This bachelor's thesis describes the design and implementation of system for the response time monitoring of network services. This thesis describes the basic techniques used for such monitoring, and describes in detail the active monitoring. The core of the resulting system is the automated responses measurement of network services using standard UNIX programs. The web interface gives a clear view of captured responses using rrdtool graphs. The web interface is also used for monitoring management.

Profiling of Network Traffic for DDoS Mitigation
Ligocká, Alexandra ; Tisovčík, Peter (referee) ; Žádník, Martin (advisor)
The aim of this work is to propose metrics for \gls{ddos} attacks detection and setting the thresholds of normal network traffic in a given computer network at different levels of detail. Based on the selected metrics and network flow data, a network profile is extracted and afterwards stored in memory. Within the implementation part, this work deals with the implementation of program for the collection and calculation of specified metrics, their processing, storage and provides a simple interface providing access to stored data.

Web Portal for Network and Application Response Time Monitoring
Bubeník, Martin ; Kaštil, Jan (referee) ; Košař, Vlastimil (advisor)
This bachelor's thesis deals with analysis, design and implementation of a system for network and services responses monitoring. The work is dedicated to two ways of tracking responses, an active one and a passive one. The active mode simulates the realistic requirements for services in the network and it measures time required for the operation. The passive method examines the response of services by means of listening on the network and by network traffic analyzing. Then, both of the methods store all consolidated data in databases. Management of monitoring and display of measured responses is provided by a web interface that allows each user to see monitored objects and to compare responses obtained by the active and the passive monitoring.
