Our guide to net security, Tony, writes, "VoIP networks, if not designed and protected properly, are vulnerable to a wide array of threats. Attackers can disrupt, or possibly even intercept communications. For organizations that have already deployed, are working on deploying, or are considering deploying a VoIP solution (that should cover just about every organization in some way), it is important to understand the security concerns, and what the countermeasures or mitigating controls are that can be used to protect your VoIP communications. In Securing VoIP Networks, Peter Thermos and Ari Takanen attempt to illustrate the many ways VoIP is vulnerable, and provide the information you need to secure it." Read his review of the book.
