Security of computer networks has become an issue of higher and higher importance.This is why we have come up with the project of Security of CESNET2Local Networks, offering security tools to the administrators of networks connectedto the academic backbone. Moreover, the tools which now help protectnetworks have witnessed significant development, sometimes based on trulyunconventional methods. We try to provide information about these systemsand their completions, which we have developed. In particular, we focus on theNESSUS, SNORT and LaBrea open source products.The purpose of the NTP Server Linked to State Time Standard is to develop andoffer out a high-quality server for time synchronization. The development workis carried out in collaboration with the Ústav radiotechniky a elektroniky (Instituteof Radio-Engineering and Electronics) of the Czech Academy of Sciences,responsible for the state time and frequency standards. We have drawn up theconcept of the entire system, comparing time information from various sources,designed the necessary proprietary hardware components and launched thepilot operation.Within the project titled Platforms for Streaming and Collaboration concerningVideocontent, we succeeded in upgrading the association’s streaming platform.This was particularly based on the launch of a proxy upload server and its linkingto the CAAS system. We also tested devices for the shared production of videodata.As well, we participated in the broadcasting of prestigious internationalconferences and other activities, co-organized by CESNET or its members.Special Videoconferences focus on the issues of high-quality videoconferences.In addition to the transmission of video signal for sectors requiring high qualityof video data, we have also concentrated on the testing of available devices andthe search for suitable technologies for videoconferences with the necessaryparameters.16 High-speed National Research Network and its New Applications 2002
