We've been running a TippingPoint IPS for over a year now without a single
failure of any kind. However, when we first installed the box it ran a few
hours and died immediately after installing the latest signatures. I
restarted it and once again it ran a few hours and died. We had temporarily
connected the management interface to one of the same network segments it was
protecting so I went ahead and setup an isolated management network and
connected the management interface there and it ran without problems. Just to
be sure that was the problem, I connected the management interface back to a
protected segment and once again it died after a few hours. With the
management interface connected to an isolated network it has never failed. I
load the signatures as soon as possible after receiving notice and have never
experienced a problem from them.

Subject: Signatures taking down network
I'm evaluating a Tipping Point box and after gettting the latest signatures
I'm having problems with the box "crashing". My goal is not to bash Tipping
Point, but instead to gather information on how often people have seen this
type of thing among IPS boxes.
Is there a trend with vendors to roll out signatures as fast as possible
without proper QA? This brings up a lot of questions about deploying IPS. I
want two opposite things from my vendors: 1) I want the latest signatures
super fast. 2) I want proper QA so that it doesn't bring down my network.
I realize those two things are contradictory, but I thought I'd throw it out
there to see if anybody had any thoughts.
thanks,
d
