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"

Do take a look at Cain & Abel (www.oxid.it) they have a voip sniffer and it
does work ver well with some implementation.
On top of all that: it is FREE

Alo Folks:
Well now we have a audit over VoIP , we need whitepappers, tools ,
links...
the big problem may be are the tools, for example we need "examples"
or "PoC like sniffing over VoIP whith tools tcpdump and Ethereal, how
to convert the traffic to .wav file , Which are the strings over my
shell use tcpdump, opensource and comercial tools.
thanks for all ur help :-)

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.
