Can Your VoIP Implementation Pass Our Security Checklist? (April 2012)

Organizations are implementing VoIP technologies in an effort to reduce costs and operating expenses and to take advantage of its feature-rich technology. While quality-of-service (QoS) is often the biggest concern companies have when migrating to VoIP, convergence of the voice and data worlds requires careful attention to security risks. Unlike traditional phone systems, which were inherently secure since the devices using its services had a physical connection to it, this is not the case with VoIP. The Internet environment can be a hostile place for VoIP deployments, as an IP-PBX can be reached from potentially anywhere in the world and is vulnerable if not properly secured. Security measures such as encrypting voice services, placing VoIP equipment behind firewalls, and defending against Denial of Service (DoS) attacks are just some of the steps you can take when introducing VoIP into your organization’s network infrastructure. Other measures include guarding against toll fraud, securing phone records, and protecting the phones. This paper identifies common security vulnerabilities and provides some of the best practices for guarding against them.

Due to the nature of IP telephony, the SIP Trunks carrying call data and passwords mainly use the public internet, providing hackers with easy access to the trunks and the data they contain. While IP phone systems offer many advantages over fixed-line telephony such as advanced call functionality and flexibility, it is precisely these advantages that can also be used against it.

IT security remains of major concern for almost any business. High-profile examples of big businesses being hacked, and sensitive customer data being leaked, continue to hit the headlines, causing significant damage to the business’ reputation and bottom line should legal proceedings ensue. Although many firms are taking steps to further secure their IT systems, it is often a different story entirely for their IP telephony network.
