Deshalb haben sich clevere Marketingstrategen gedacht man könnte doch für jeden Rechner eine verkaufen.\n\nDabei werden die Benutzer bezüglich der Funktionalität getäuscht. Es wird eine Sicherheit versprochen, die eine Personal Firewall prinzipbedingt nicht bringen kann. Statt dessen ermöglichen sich durch das Vorhandensein einer Personal Firewall ganz neue Angriffsmöglichkeiten auf ein System.\n\nIm Vortrag wird erklärt, wie Personal Firewalls funktionieren. An Hand von ein paar Beispielen wird anschließend gezeigt, wie man eine Personal Firewall umgehen oder angreifen kann.\n\nLinks:\n\n- Google Video: \u003ca href=\"http://video.google.de/videoplay?docid=-9179940514495321914\"\u003ehttp://video.google.de/videoplay?docid=-9179940514495321914\u003c/a\u003e\n- Seite zum Vortag: \u003ca href=\"http://blog.copton.net/articles/pfw-versagen/\"\u003ehttp://blog.copton.net/articles/pfw-versagen/\u003c/a\u003e\n- Windowsdienste abschalten: \u003ca href=\"http://www.dingens.org\"\u003ehttp://www.dingens.org\u003c/a\u003e\n- Mehr zum Thema \u003ca href=\"http://ulm.ccc.de/PersonalFirewalls\"\u003ePersonalFirewalls\u003c/a\u003e\n\nMehr Infos: \u003ca href=\"https://ulm.ccc.de/ccc/chaosseminar/2004_12_Personal_Firewalls\"\u003ehttps://ulm.ccc.de/ccc/chaosseminar/2004_12_Personal_Firewalls\u003c/a\u003e","original_language":"deu","persons":["Alexander Bernauer","Ansgar Wiechers","[Jonathan Häberle](http://dreampulse.de)"],"view_count":24,"promoted":false,"date":"2004-12-13T20:00:00.000+01:00","release_date":"2026-11-04T00:00:00.000+01:00","updated_at":"2026-11-07T13:00:08.183+01:00","tags":["110831","2004","ulm","Chaosseminar","CCCUlm","ulm-deu"],"length":5358,"duration":5358,"thumb_url":"https://static.media.ccc.de/media/contributors/ulm/110831-4798732b-cfc2-4289-baf2-1ebf0d9c51b9.jpg","poster_url":"https://static.media.ccc.de/media/contributors/ulm/110831-4798732b-cfc2-4289-baf2-1ebf0d9c51b9_preview.jpg","timeline_url":"https://static.media.ccc.de/media/contributors/ulm/110831-4798732b-cfc2-4289-baf2-1ebf0d9c51b9.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/contributors/ulm/110831-4798732b-cfc2-4289-baf2-1ebf0d9c51b9.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ulm-110831-personal-firewalls","url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_title":"ChaosSeminar Ulm","conference_url":"https://api.media.ccc.de/public/conferences/ulm","related":[],"recordings":[{"length":5358,"mime_type":"video/mp4","language":"deu","filename":"import-110831-deu-Personal_Firewalls_hd.mp4","state":"new","folder":"h264-hd","high_quality":true,"width":320,"height":240,"updated_at":"2026-11-04T02:53:44.162+01:00","label":"deu 240p","size":124,"recording_url":"https://cdn.media.ccc.de/contributors/ulm/h264-hd/import-110831-deu-Personal_Firewalls_hd.mp4","url":"https://api.media.ccc.de/public/recordings/106909","event_url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_url":"https://api.media.ccc.de/public/conferences/ulm"},{"length":5358,"mime_type":"audio/opus","language":"deu","filename":"import-110831-deu-Personal_Firewalls_opus.opus","state":"new","folder":"opus","high_quality":false,"width":0,"height":0,"updated_at":"2026-11-04T04:04:38.101+01:00","label":"deu","size":50,"recording_url":"https://cdn.media.ccc.de/contributors/ulm/opus/import-110831-deu-Personal_Firewalls_opus.opus","url":"https://api.media.ccc.de/public/recordings/106932","event_url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_url":"https://api.media.ccc.de/public/conferences/ulm"},{"length":5358,"mime_type":"audio/mpeg","language":"deu","filename":"import-110831-deu-Personal_Firewalls_mp3.mp3","state":"new","folder":"mp3","high_quality":false,"width":0,"height":0,"updated_at":"2026-11-04T04:06:04.245+01:00","label":"deu","size":82,"recording_url":"https://cdn.media.ccc.de/contributors/ulm/mp3/import-110831-deu-Personal_Firewalls_mp3.mp3","url":"https://api.media.ccc.de/public/recordings/106933","event_url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_url":"https://api.media.ccc.de/public/conferences/ulm"},{"length":5358,"mime_type":"video/mp4","language":"deu","filename":"import-110831-deu-Personal_Firewalls_sd.mp4","state":"new","folder":"h264-sd","high_quality":false,"width":720,"height":576,"updated_at":"2026-11-04T04:06:11.586+01:00","label":"deu 576p","size":203,"recording_url":"https://cdn.media.ccc.de/contributors/ulm/h264-sd/import-110831-deu-Personal_Firewalls_sd.mp4","url":"https://api.media.ccc.de/public/recordings/106934","event_url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_url":"https://api.media.ccc.de/public/conferences/ulm"},{"length":5358,"mime_type":"video/webm","language":"deu","filename":"import-110831-deu-Personal_Firewalls_webm-sd.webm","state":"new","folder":"webm-sd","high_quality":false,"width":720,"height":576,"updated_at":"2026-11-04T05:18:47.158+01:00","label":"deu 576p","size":188,"recording_url":"https://cdn.media.ccc.de/contributors/ulm/webm-sd/import-110831-deu-Personal_Firewalls_webm-sd.webm","url":"https://api.media.ccc.de/public/recordings/106990","event_url":"https://api.media.ccc.de/public/events/4798732b-cfc2-4289-baf2-1ebf0d9c51b9","conference_url":"https://api.media.ccc.de/public/conferences/ulm"}]}
