Carleton University - School of Computer Science Undergraduate Honours Project Fall 2009 Security Concerns with WIreless Voice over IP Josh Mahonin 
ABSTRACT Voice over IP, or VoIP, is fast becoming a widely used means of communication, and is now becoming popular over wireless 802.11 networks. Although the use of this technology is convenient and cost-effective, the findings in this project show that doing so without proper security precautions is potentially dangerous and open for abuse from malicious users. This project details general vulnerabilites from an information security perspective, as well as specific methods of attack that could be used to subvert this technology, such as eavesdropping on calls, changing call behavior, and disabling access to call facilities all together. A threat analysis of the attacks are performed for a number of scenarios in order to classify the risk of each. Using both conclusions derived from this project, as well as findings from other security researchers, a number of strategies are suggested to mitigate the risk in using this technology. |
