RE: RADWare Link Proof Questions

Hi,

This is a known configuration issue. The hashing is probably not activated on the linkproof, and therefore the "client 
table" literally "explodes" when you scan through the box.

Cheers,

What type of scan did you used? I have noticed the
same behavior with another type of load balancing
device during FIN scans.

Have secure fun,

Hi All -

I've been conducting a pen test against a client who
has RADWare's
Link Proof devices to perform load balancing across
their Internet
connections.  While running my scans (basic TCP port
scans and such)
they claim that their load balancers basically
rolled-over and died
causing Internet outages (inbound and outbound).

Has anyone else seen this kind of behavior?

Are their configuration settings on the Link Proof
that would prevent
this or is this simply a vulnerability with the load
balancers?

Just as a point of reference, I was sourcing the
scan from a cable
modem connection (max 768K up) and wasn't trying to
blast them or
anything (they are a client after all); it just
seems strange to me
that my scans were able to do this considering that
they have a couple
of DS3s of bandwidth coming in.

Any info/advice would be appreciated.

Thanks,

RBK
