Summary
Voice over Internet Protocol (VoIP) transforms voice communications into another application on an Internet Protocol (IP) network. Unfortunately, with VoIP an organization also inherits all the risks of a data network, including worms and viruses, Denial of Service (DoS) attacks, spam, and even phishing. Furthermore, traditional firewall technologies can complicate several aspects of VoIP, most notably dynamic port trafficking and Network Address Translation (NAT) transversal. Security product vendors are adding functions that address voice applications in their products, but as history has shown, security typically lags behind advances in technology.
To assess the impact of VoIP in the security appliance market, In-Stat conducted an end-user survey to discover trends in security product usage and plans for future purchases. In addition to the results of the survey, the report also includes vendors market shares and a five-year forecast for security appliances.
