challenges in capturing Gigabit ethernet

[Siddharth Phadnis <sphadnis () clear-trail com>]

Hi All,

Vendors have long been talking about gigabit ethernet capabilities of
their IDS/IPS. It got me thinking that is it just a simple matter of
installing a gigabit ethernet card in the appliance and capturing the
packets or is there any specialized hardware which is required.

In effect, what all challenges are involved in capturing packets off a
gigabit ethernet network so that packets do not drop. Does it just
involve the hardware or are there some considerations in software too?

Regards,
Siddharth
