Multi-Layered VoIP Security
Available from Radware Ltd
VoIP communication brings another dimension into the security challenge by introducing both control (signaling) and content (voice) parallel channels which together form the VoIP service. The dependence of these channels on one another drastically increases the risk that VoIP service can be damaged, as each one of the channels has its own vulnerabilities. It doesn’t matter which vulnerability is exploited because the attack renders the whole service useless.
A comprehensive, multilayer risk mitigation strategy must be implemented in combination with native IP telephony features and standard network security measures. Failure to do so is likely to expose a company to security breaches and service disruptions, resulting in expensive reactive measures.
