Overview: VoIP and Unified Communications are changing the telecommunication landscape. Business benefits, new feature and significant cost reduction in deploying and managing telecommunication networks makes Voice over IP (VoIP) an attractive replacement for the existing TDM technologies. While VoIP inherits the same security threats as the IP data network it also introduces new ones that are specific to the IP based communications. Furthermore, existing compliance and regulatory requirements defined by SOX, GLBA and HIPAA apply to VoIP, intensifying the pressure on the enterprises to audit and secure voice networks.
Most enterprises deploying VoIP have already invested significant resources in securing their data networks using a combination of security applications, devices and processes. However, traditional IT security products are not equipped to address the new challenges associated with securing voice systems. Organizations must understand that VoIP security is not a simple extension of the existing security infrastructure and processes. It requires in-depth understanding of telecommunication concepts, VoIP protocols and applications, IP networks and security.
