McAfee® IntruShield® IPS 4.1 IntruShield Sensor 1400 Product Guide An introduction to IntruShield sensors The IntruShield 1400 Sensor 8 Built-in internal tap (not shown). The internal tap (used with the 10/100 ports) provide stealth mode monitoring functionality and forgo the need of an external tap or connection to a SPAN port or hub. When the 10/100 ports are configured to monitor a network segment in peer mode, their internal tap allows a network segment to be connected directly to the sensor: one port receives/transmits from Device A (For example, a firewall, router, switch) and the other receives/transmits from Device B. You can also change 'on the fly' from internal tap mode to in-line mode. Note: Internal taps fail open, meaning that should the sensor fail physically while running in internal tap mode, the connection is not disrupted; your network traffic will continue to flow unimpeded (although there may be a minor disruption as the network devices surrounding the sensor establish direct connectivity). If you want to have fail-closed functionality, you can accomplish this via cabling. Normal Cat 5/Cat 5e cabling will fail open. Special cabling using the supplied failclosed dongles provides fail-closed functionality. For more information, see the section, Cabling the Monitoring ports (on page 15).

Built-in internal tap (not shown)
. The internal tap (used with the 10/100 ports) provide
stealth mode monitoring functionality and forgo the need of an external tap or
connection to a SPAN port or hub. When the 10/100 ports are configured to
monitor a network segment in peer mode, their internal tap allows a network
segment to be connected directly to the sensor: one port receives/transmits from

receives/transmits from Device B. You can also change ‘on the fly’ from internal
tap mode to in-line mode.
Note:
Internal taps
fail open
, meaning that should the sensor fail physically while
running in internal tap mode, the connection is not disrupted; your network traffic
will continue to flow unimpeded (although there may be a minor disruption as the
network devices surrounding the sensor establish direct connectivity).
If you want to have fail-closed functionality, you can accomplish this via cabling.
Normal Cat 5/Cat 5e cabling will fail open. Special cabling using the supplied fail-
closed dongles provides fail-closed functionality. For more information, see the
