This whitepaper discusses security challenges posed by voice over IP (VoIP) communications in wired and wireless devices, such as VoIP servers, gateways, telephones, and mobile handhelds. The author describes a number of techniques that can be used by developers to help protect VoIP devices from security breeches. The paper is from Certicom, which markets Security Builder toolkits to embedded Linux developers.

Author Rick Pitz contends that securing a VoIP device is a multi-level process, with several options and implementations possible. From the viewpoint of a developer, the selection of a security architecture needs to take into account the real likelihood that the security solution will migrate over time, as new requirements and applications are introduced. A flexible, extensible strategy is required to ensure the ease of adapting to ever changing requirements, he suggests.
