Sikkerhet i Trådløse Nettverk

Abstract

NORSK: På tross av tallrike sikkerhetshendelser hår trådløse nettverk utviklet seg til å bli et virksomhetskritisk tilbud i dagens IT-infrastruktur. Med ratifiseringen av IEEE 802.11 standarden skulle man tro at ting hadde endret seg. Denne masteroppgaven viser, gjennom et teoristudium av sikkerheten rund 802.11-standarden, at kompleksiteten er omfattende med mange metoder å velge fra. Særlig kartleggingen av metoder for autentisering har vist seg å være omfattende, samt det å vise helheten og sammenhengen mellom de ulike metodene for sikring av WLAN. Gjennom teoristudier har det vært overraskende å se diskrepansen mellom kravene akademisk litteratur stiller til autentisering i et trådbasert nettverk versus et WLAN etter 802.11 standarden. Mens førstenevnte fremhever to-faktor autentisering som den mest robuste metoden, og da særlig i forhold til tilgang fra fremmede nett, er det oppsiktsvekkende lite fokus på dette i trådløse nettverk. Det har i dette studiet blitt laget en rangering for godheten av ulike metoder for autentisering, konfidensialitet og integritet i WLAN, og metoder i kombinasjon.
