Assembling an arsenal of VoIP Security Tools to assess various VoIP platforms is quite cumbersome and
much different from cobbling together a list of non−commercial network security tools and commercial
network security tools. SiviUS is a nice tool but it is not quite complete, as it does not test for H.323 or SIP
transformation validation and other such features.

Being able to have a product that is capable of producing threshold index on various VoIP measurements
including a security index on the specific vulnerabilities it checks for would be a great help in accessing a
network infrastructure migrating to VoIP or reviewing a newly integrated VoIP solution.

Measurement Rating Index
MOS 1.0 −−> 200.00 1−−>5
Delay
Jitter
Loss

Results accumulated by x number of endpoints, and pertinent variables: (RTP, Jitter, RTP, QOS, Frame
Compression, Payload (GSM, G711, etc), Min calls, Max calls, cycle

Includes a packet capture and playback feature (mostly likely Ethereal with statistical plug−ins)
Can be run from any platform (.tar.gz for U*nix and installshield for Windows especially for those security
consultants who are far from click here, crank there methodology.
Security Feature checking ability (oscheck for specific VoIP products, using nmap will reveal the underlying
operating system (sometimes attractive) but one is more interested in what the particular VoIP vendor
implemented on top of the underlying operating system, or if certain libraries have been removed to avoid the
"oops, can be compromised warning/red flagging" the hopped up on "RED BULL" or "CROSS YOUR
HEART: security consultants tend to point out in the fancy long−winded report.

If a VoIP assessment report is more than 10 pages without a fair amount of self−explanatory graphs, "do not
pass GO, and start again"

I think Cain & Abel will have a problem with g723 codec. I've tried
sniff using Ethereal and it works well. Just that u need some additional
tools such as JmStudio and rptplay.
