Lab exercise of electronic burglar alarm system with communication over Ethernet network
Harth, Petr ; Pust, Radim (referee) ; Burda, Karel (advisor)
This bachelor thesis deals with electronic burglar alarm systems that communicate over Ethernet network. On this basis, the lab exercise is designed for an integrated security system Xtralis 3000 to ensure access control and camera surveillance. The concept of lab exercise is justified, and prepared documentation for it. Subsequently, a brief analysis of the Xtralis 3000 system security is also made. The first part describes the development of electronic burglar alarm systems. The history as well as current state of the art of electronic burglar alarm systems are outlined. Also camera surveillance systems and access systems, which are nowadays combined with electronic burglar alarm systems, are briefly mentioned. The thesis goes on by describing the current trend of integrating various security systems into one system that communicates over Ethernet network. In the second part of this thesis the integrated security system Xtralis 3000 is being analyzed. First of all its general characteristics are described and then it goes on by explaining the distribution of the three subsystems, namely the access system S3000, the camera surveillance system V3000 and management software M3000. Subsequently, these systems are being described along with their features. After that, selected network protocols, which integrated security system Xtralis 3000 uses to communicate between its components, are being briefly discussed. In the third part a brief analysis of security integrated security system Xtralis 3000 is carried out. This system is divided into six parts in terms of threats of attacks. The fourth section it is devoted to the concept of lab exercise, which includes introductory balance sheet, the debate over the assigned elements, content and structure of the lab exercise. In the fifth part, is the thesis offers documentation to the lab exercise of integrated security system Xtralis 3000 communicating over Ethernet network, according to which students may perform this lab exercise. And finally, in the sixth part are the instructions for teachers, which describe how to introduce the lab exercise in teaching, with the associated problems and their solutions.

Geolocation in Internet using latency measurements
Harth, Petr ; Balej, Jiří (referee) ; Komosný, Dan (advisor)
This diploma thesis is concerned with practical realization of CBG (Constraint-based Geolocation) algorithm, which is one of the IP (Internet Protocol) geolocation technique. IP geolocation determines the localization of a computer workstation location on the basis of on its IP address. The factors causing delays in data transfer are discussed first, followed by discussion of the issue of measuring these delays. The detailed explanation of IP geolocation follows where its contexts as well as the active geolocation techniques (techniques based on delay measurement mentioned above) are described. After that a brief description of PlanetLab experimental network, which was used for geolocation techniques measuring, is presented followed by a section explaining the creation of reference points and targets, which are another necessary prerequisite for practical realization of the method. Then the practical realization is explained in the form of CBGfinder program and its verification on the basis of artificial input data along with an actual example of IP geolocation of a point in the Internet are provided. Last but not least the measurement results of CBG algorithm are introduced, based on the analysis of Bestline parameters of one of the PlanetLab nodes measured in the period of one month, followed by a discussion of the inaccuracy of geological position and the computation speed. The cumulative distribution function as well as the kernel density estimation are also described. Final part of the thesis consists of discussion on measured results compared to results of other geological techniques results implemented by colleagues of the author of this diploma thesis. The results are compared on the basis of average inaccuracy of geological position estimations and its median, computation time, cumulative distribution function and kernel density estimation are also taken into regard.
