About the Book

Studienarbeit aus dem Jahr 2014 im Fachbereich Medien / Kommunikation - Fachkommunikation, Sprache, Note: 1,3, Technische Hochschule Köln, ehem. Fachhochschule Köln (Mehrsprachige Kommunikation), Sprache: Deutsch, Abstract: Wireless Local Area Networks (WLAN) sind aus unserem digitalen Alltag nicht mehr wegzudenken. Der drahtlosen Netzwerktechnologie liegt ein Industriestandard zugrunde, dessen Entwicklung gegen Ende der achtziger Jahre abgeschlossen war. 1997 wurde der 802.11-Standard verabschiedet und erste Geräte wurden hergestellt.

Sich unterwegs per Smartphone oder Laptop in ein öffentliches WLAN einzuloggen und zu surfen, scheint daher bequem zu sein. Es gibt aber auch eine Schwachstelle der drahtlosen Netzwerktechnologie: Die Sicherheit. Im Folgenden werde ich Ihnen eine sehr wichtige Sicherheitsmaßna
