CHEP conferences provide an international forum to exchange information on computing experience and needs for the High Energy Physics community, and to review recent, ongoing and future activities. CHEP conferences are held every 18 months, the previous one being held in San Diego in March 2003. False Interlaken, Switzerland

Brunig 3 2004-09-29T14:40:00 2004-09-29T15:00:00 00:20 Implementing strategies for secured access to widely accessible clusters is a basic requirement of these services, in particular if GRID integration is sought for. This issue has two complementary lines to be considered: security perimeter and intrusion detection systems. In this paper we address aspects of the second one. Compared to classical intrusion detection mechanisms, close monitoring of computer services can substantially help to detect intrusion signs. Having alarms indicating the presence of an intrusion into the system, allows system administrators to take fast actions to minimize damages and stop diffusion towards other critical systems. One possible monitoring tool is Nagios (www.nagios.org), a powerful GNU tool with capacity to observe and collect information about a variety of services, and trigger alerts. In this paper we present the work done at CIEMAT, where we have applied these directives to our local cluster.We have implemented a system to monitor the hardware and system sensitive information. We describe the process and show through different simulated security threads how does our implementation respond to it. paper doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link slides doc http://indico.cern.ch/images/word.png word file ppt http://indico.cern.ch/images/powerpoint.png powerpoint file pdf http://indico.cern.ch/images/pdf_small.png pdf file odt http://indico.cern.ch/images/writer.png writer file odp http://indico.cern.ch/images/impress.png presentation file ods http://indico.cern.ch/images/calc.png spreadsheet file other http://indico.cern.ch/images/file_small.png unknown type file link http://indico.cern.ch/images/link.png link 2013-06-19 2013-06-20
