If you are going to incorporate a switching hub technology into your
security infrastructure it
is probably best to look for a technology capable of integrating into your
existing management
platform.
Of second importance, does this hub technology provide physical layer
security and the ability to store
multiple configurations that can be quickly incorporated into the current
physical environment. This
will allow you to ensure the appropriate corporate resources are physically
segregated from any attack.
In an ideal scenario, you would want to have multiple configurations that
would include variations for
different types of attacks (i.e. mail gateway, coporate services, host
connectivity). In this case, the
operator could make an intelligent based decision to only remove those
services under attack.
It is important to remember that the hub you are considering is a physical
layer device, not a encapsulating
switch. Using this type of technology may become another security issue.
I would suggest you look into the Bytex switching hubs (Token-Ring and
Ethernet).
