SIP based IP-telephony network security analysis
Abstract
This thesis evaluates the SIP Protocol implementation used in the Voice over IP (VoIP) solution at
the fibre/DSL network of Èlla Kommunikasjon AS. The evaluation focuses on security in the
telephony service, and is performed from the perspective of an attacker trying to find weaknesses
in the network.
For each type of attempt by the malicious attacker, we examined the security level and possible
solutions to flaws in the system.
The conclusion of this analysis is that the VoIP service is exploitable, and that serious
improvements are needed to achieve a satisfying level of security for the system.
