VOIP Security

Definition: VOIP Security (Voice Over Internet Protocol) relates directly to the confidentiality, integrity and availability of voice communications. Many of the same challenges exist with the security of audio communications on the Internet as those that exist with the web and computer networks. Voice is transmitted as data over the Internet in packets. A completely different set of infrastructure components are utilized than with traditional verbal communications.

Generally the threats and vulnerabilities associated with IP (Internet Protocol) remain the same.

Its Relevance: Transmitting voice over the Internet is more complex than the traditional publicly switched network. A different investment in infrastructure is required to provide for secure communications. Significantly powerful processing units must be used to make voice over the Internet communications possible. The technology is emerging and the organization’s information security policies need to address how voice over the Internet is to be securely processed.
