Detection of Voice Spam (SPIT)
VoDaSec's patent-pending technology addresses the enterprise and carrier service
proider's need of detecting voice spam attacks without any infrastructure
changes. VoDaSec's SPS works without requiring call history or reputation value
of callers and also does not perform any type of Turing tests. SPS correlates
INVITE attributes and applies statistical methods to raise an alarm. The
detection resolution is our own choice varying from a fraction of a second to
couple of seconds.

Flash Crowds /
DDoS Attacks
Both of these events degrade the performance of a SIP proxy sever to a point
where it becomes sluggish and even unresponsive.
VoDaSec's patent-pending technology not only performs an early
detection, but distinguishes between the two, so that a differential treatment
can be given to both types of traffic.

Needles from
the Haystack
VoDaSec's patent-pending technology is based on a heuristic that allows to
select good traffic from the DDoS attack traffic. The selective admittance of
legitimate traffic not only protects the call processing server, but keeps on
serving customers as well.
