Re: IPS/IDS location suggestions in Network.

["Gleb Paharenko" <gpaharenko () gmail com>]

Hi.

For a pity I do not have an experience in implementing IPS on 10g links,
however I've been researching IBM appliances (ISS+Proventia). In practice
they can not do the deep inspection by signature patterns in protocols
which is higher
than transport layer (i.e. checking for an exploit code) at even
several G speed. Not sure if they just skip checks for packets or it
will became a bottleneck in case you try to force all packets to be
checked. You should talk with IBM specialists what set of features
will be available on that speed.
