Abstract

As an IP application, Voice over the Internet Protocol is vulnerable to a number of attacks. Security is an essential consideration for VoIP providers since each component in the VoIP infrastructure can be used as a target, and VoIP has specific security challenges as well. Firstly, this paper discusses general aspects of VoIP. Secondly, the paper addresses these aspects to discuss security issues and concerns of this new technology. Finally, the paper considers some security challenges that VoIP systems are facing.
