threats impacting the SIP based devices. The appliance has been made to seamlessly integrate
with the existing network infrastructure and reduces the complexity of deployment.
The appliance feature set includes,
Analyze SIP packets using the Realtime Deep Packet inspection engine.
SIP Protocol Anomaly detection with configurability of detection parameters.
Detection and Prevention of the following categories of SIP based Attacks.
Reconnaissance attacks ( SIP Devices Fingerprinting, User enumeration, Password
Cracking Attempt )
Dos/DDos Attacks
Cross Site Scripting based attacks.
Buffer overflow attacks
SIP Anomaly based attacks
3rd Party vendor vulnerabilities
Toll Fraud detection and prevention
