How Secure is VoIP?


Given all the hoopla around voice over the internet Protocol, not many have talked about the security risks involved in this technology. Elisabeth Ussher, an analyst with The Meta Group points out that the “current IP telephony products and implementations demonstrate an alarming lack of protective security measures, leaving the enterprise open to privacy violation, fraud, and malicious attacks.” Although current telephony implementations require security measures to deter basic toll fraud and voice-mail intrusion, these systems are not connected with the corporate data infrastructure and are thereby detached from corporate security. However in the future, the focus has to shift to security. “Organizations that adopt voice over IP without a cross-discipline security review are at risk for lost revenue and productivity, including data theft,” says Ussher, an adds, “Enterprises must consider security in the initial IP telephony design and must adopt holistic security policies.”
