a

in
the
registration
web
page.
This
sponsor
username
and
password
can
be
validated
against
an
existing
database
on
the
network
to
authenticate
the
sponsor
ʹ
s
identity.
Sponsors
may
be
allowed
to
securely
access
an
administrative
web
page
where
they
can
delete,
add,
and
modify
registered

systems
on
the
network
that
they
have
sponsored.
With
sponsored
registration
enabled,
IT
operations
can
hold
trusted
users
accountable
for
guests
brought
on
the
enterprise
network,
while
controlling
access
for
only
appropriate
guests.
Post-Connect NAC integration with NetSight Automated Security Manager
NetSight
Automated
Security
Manager
(ASM),
a
software
application
that
is
part
of
the
NetSight
Suite,
has
the
capability
to
search
the
infrastructure
and
locate
the
switch
port
of
connection,
based
on
the
receipt
of
a
security
event
for
a
particular
IP
address.
ASM
responds
to
this
event
by
disabling
the
port
or
assigning
a
VLAN
(such
as
the
quarantine
VLAN)
to
the
port.
In
response
to
a
real
‐
time
security
threat
detected
on
the
network,
ASM
can
be
configured
to
notify
NAC
Manager
on
this
event,
dynamically
quarantining
the
MAC
address.
This
effectively
restricts
the
quarantined
end
‐
system
from
accessing
the
network
from
any
location,
enterprise
‐
wide.
If
ASM
reverses
the
quarantine
action,
it
notifies
NAC
Manager,
and
the
quarantine
is
automatically
removed
and
the
end
‐
system
is
dynamically
re
‐
admitted
access
to
network
resources.
Therefore,
the
deployment
of
Enterasys
NAC
further
increases
the
security
posture
of
the
network
by
integrating
with
the
reactive
threat
response
capabilities
of
ASM,
in
addition
to
controlling
access
and
authorizing
connecting
devices.
Required and Optional Components
This
section
summarizes
the
required
and
optional
components
for
Model
2.
.
The
NAC
Gateway
and
NAC
Controller
are
the
NAC
appliances
used
to
implement
the
out
‐
of
‐
band
and
inline
network
access
control
functionality
on
the
network.
NetSight
NAC
Manager
is
the
software
application
used
to
centrally
manage
the
NAC
appliances
deployed
on
the
network.
NetSight
Console
is
the
software
application
used
to
monitor
the
health
and
status
of
infrastructure
devices
in
the
network,
including
switches,
routers,
and
Enterasys
NAC
appliances
(NAC
Gateways
and
NAC
Controllers).
Assessment
functionality
is
optional
because
in
this
deployment
model,
end
‐
systems
are
not
being
assessed
for
security
posture
compliance
when
connecting
to
the
network.
