16. 03. 2015: Internet Technologen der HAW Hamburg präsentieren neue Wege zur Cyber Security auf der CeBIT 2015

Das Internet ist zur kritischen Infrastruktur geworden – Industrie und Handel, Staatsführung und Banken, nahezu alle Bereiche eines Landes sind heute auf ein funktionierendes Internet angewiesen. Gleichzeitig ist aber das Rückgrat des Internets, die Internet-Pfadverhandlung mit dem ‚Border Gateway Protocol‘ (BGP), weitgehend ungeschützt gegen Konfigurationsfehler und betrügerische Manipulationen. Die Hamburger Informatiker stellen auf dem diesjährigen Cebit-Forschungsstand der Bundesregierung neueste Sicherheitslösungen für das Internet Routing vor. Präsentiert werden die Ergebnisse aus drei Jahren gemeinsamer Forschungsarbeit mit der FU Berlin, der TU München und den führenden deutschen Internet-Knotenpunkten im Projekt Peeroskop, welches vom Bundesministerium für Bildung und Forschung (BMBF) mit 1,7 Millionen Euro gefördert wird.

03.03.2014: Informatiker der HAW Hamburg präsentieren auf der CeBIT 2014, wie das Internet der Dinge die zivile Sicherheit der Menschen verbessert ohne ihre Privatsphäre zu verletzen

Massenansammlungen an öffentlichen Orten können plötzlich in Massenpaniken umschlagen, Überfüllung kann z.B. einen Flughafen zur gefährlichen Falle werden lassen. Doch rechtfertigt die eventuelle Gefahr unsere ständige Überwachung? Die Internet-Technologen der HAW Hamburg weisen einen anderen Weg: Im Internet der Dinge können kleine Sensoren kritische Menschenmengen entdecken - ohne einzelne Personen per Video zu überwachen. Erste Ergebnisse sind nun vom 10. bis 14. März auf der Cebit in Hannover zu sehen. Gefördert wird das Projekt vom Bundesministerium für Bildung und Forschung (BMBF) und der französischen ANR mit insgesamt 2,6 Millionen Euro.

01.03.2012: Vitamin C für das Smartphone: Informatiker der HAW Hamburg präsentieren Sicherheitslösungen für Smartphones auf der CeBIT 2012

Immer mehr Arbeitgeber statten ihre Mitarbeiter mit Smartphones aus, doch die mobilen Endgeräte sind anfällig für Viren und der Schutz der eigenen Daten ist nicht immer gewährleistet. Informatiker der HAW Hamburg arbeiten an Sicherheitslösungen für Smartphones und stellen erste Ergebnisse auf der diesjährigen CeBIT vom 6. bis 10. März vor. Gefördert wird das Projekt vom Bundesministerium für Bildung und Forschung (BMBF) mit rund 900.000 Euro.
