As voice networks have moved to IP technology, they've inherited many of the same vulnerabilities as IP-based data networks: Denial of Service attacks, spam, information/identity theft and other malicious attacks. While Session Border Controllers (SBCs) can protect voice networks against many kinds of attacks, they lack the application awareness necessary to completely protect critical applications like call centers and voicemail systems. Sonus voice security systems can fill in those security gaps, providing a holistic security solution that, together with SBCs, protects both IP and legacy voice networks from a wide range of internal and external attacks.
Sonus VoiceSentry
Botnet-based networks and Telephony Denial of Service (TDoS) represent a new and dangerous threat to public and private voice networks. Sonus VoiceSentry is an application-aware security solution designed to protect enterprise call centers and voice networks against machine-generated and TDoS attacks. VoiceSentry uses adaptive intelligence and Call Detail Records (CDR) analysis to identify, profile and block suspicious and malicious calls before they reach call centers and critical network resources. In addition, VoiceSentry includes unique voice CAPTCHA technology that filters out machine-generated traffic in much the same way that data CAPTCHA works: through a prompt or challenge that requires human intelligence to pass.
