RE: Voice over IP applications vulnerabilites/attacks ?

[Avi Chesla <avic () V-Secure com>]

Hi,

Excellent articles and master's thesis.

Thank you.

Your thesis mainly talks about the detection algorithms. Do you have
something about the prevention algorithms as well?

All,

Do you or anyone else familiar with products that focus on the VoIP area
(SIP proxy vulnerabilities) mainly in the detection of flood attacks (DDoS
or DoS) ?.

Best Regards,

Avi Chesla

Avi,

        I have spent a good part of the past year working with IP telephony
and evaluating the weaknesses associated with it. I have written several
papers about my work including an IEEE Communication magazine article
(http://www.off-pisteconsulting.com/research/pubs/ieee_comm.pdf), a paper
for the upcoming NDSS conference
(http://www.off-pisteconsulting.com/research/pubs/ndss03-reynolds.pdf) and
my Master's thesis
(http://www.off-pisteconsulting.com/research/pubs/reynolds-ms_thesis.pdf).
The thesis is the most comprehensive document on the subject. If you have
any questions about the material please let me know.
