Abstract

Prijenos govora u paketskoj komunikacijskoj mreži tehnologija je za koju se predviđa da bi u godinama koje dolaze trebala zamijeniti tradicionalnu javnu komutiranu telefonsku mrežu. Sa širenjem Voice-over-IP-a u kućnim i poslovnim primjenama, glavni zahtjevi kod uvođenja su osiguravanje niskih vremena kašnjenja, kvalitete glasa i usluge te ušteda troškova. Potreba za sigurnom i pouzdanom komunikacijom često je zanemarena. Ovaj rad usredotočen je na ranjivosti i najčešće izazove iskorištavanja ranjivosti Voice-over-IP sustava. Laboratorijski model VoIP sustava zasnovan na aktualnim softverskim rješenjima korišten je za prikaz čestih vrsta napada kako bi se predložile tehnike i najbolje prakse za procjenu rizika i ublažavanje napada u VoIP sustavima.

Abstract (english)

Transmission of speech in packet communication network is a technology which should replace traditional public switched telephone network in years to come. With the expansion of Voice-over-IP in both home and enterprise applications main concerns regarding implementation of such systems are low latency, voice and service quality and cost savings. Concerns regarding security are often being overlooked. This thesis focuses on vulnerabilities and common exploitation challenges in Voice-over-IP systems. Laboratory model based on relevant software solutions was used to demonstrate common types of attacks in order to provide suggestions of techniques and best practices for risk assessment and attack mitigation in VoIP systems.
