IDS: RE: IPS Reliability/Availability

[CraigPaterson () Halifax co uk]

Network critical do a range of inline taps in their v-line range.
you have two ips units connected to this unit and in normal working your live traffic will pass through the primary 
unit. If the primary dies then the traffic is re-routed via the secondary. If this fails then the unit will go into 
bypass mode. The unit also goes to bypass on power or any other problems with the tap.

We use these units with Packetshapers and they work very well, during testing we experienced a maximum of 2 secs 
downtime during failure scenarios.

I know from the short time I worked for a Juniper reseller, the Juniper IPS
has a separate box [very small] that does like a HA link to the IPS, so if
the IPS fails, the traffic routed straight throught the network with no IPS

I am working on a big IPS project and I am very concerned about installing
an inline device in a core enterprise network, where these devices have the
potential to create big time network outages. 

Can you, please, share your possible bad experiences about the reliability
of the following inline IPS products:

ISS
TippingPoint
Juniper IPS
Sourcefire
McAfee IntruShield

Have you had any issues with the availability of these devices, such as fail
close crashes or do you have any experience with bypass switches that would
mitigate the availability issue?

Thanks,
Mike
