VmSat
A tool for VoIP monitoring and security assessment

VmSat monitors, analyzes and tests the VoIP infrastructure and VoIP services provided by vendor. VmSat has two main services: monitoring service and security service.

As a basic monitoring service, this tool monitors and performs analysis of the real time VoIP traffic for troubleshooting the infrastructure bottlenecks. It provides various quality metrics for voice traffic in terms of bandwidth utilized, delay, jitter, packet loss, R-Factor, and MOS. It quickly provides comprehensive remedial reasoning for quality deterioration.

As a security service, the tool assesses the VoIP infrastructure against security threats. VmSat provides several most generic attack templates and launches attacks (flood attacks, message attacks, etc.) within the system to identify the vulnerabilities present in the system. Robustness of SIP protocol implementation is assessed through rigorous checks.

VmSat also provides a comprehensive and generic meta language to assist in generation of any custom attacks. It consists of a plaintext format like an English sentence which provides a high degree of flexibility to the user. Once vulnerabilities are identified, it provides remedial information that enables security professionals to perform appropriate actions.
