About Network Security Sensors
McAfee Network Security Sensor (Sensor) (Sensors) are high-performance, scalable, and flexible
content processing appliances built for the accurate detection and prevention of:
•
Network intrusions
•
Network misuse
•
Distributed Denial-of-Service (DDoS) attacks
Sensors are specifically designed to handle traffic at wire speed, efficiently inspect and detect
intrusions with a high degree of accuracy, and flexible enough to adapt to the security needs of any
enterprise environment. When deployed at key network access points, the Sensor provides real-time
traffic monitoring to detect malicious activity and respond to the malicious activity as configured by
the administrator.
After you deploy a Sensor successfully, you configure and manage it using the McAfee® Network
Security Manager (Manager). The process of configuring a Sensor and establishing communication
with the Manager is described in the subsequent chapters of this guide. For the details about the
Manager, see the McAfee Network Security Platform Manager Administration Guide.

About Network Security Sensors
Deployment of an NS-series Sensor
The primary function of a Sensor is to analyze traffic on selected network segments and to respond
when an attack is detected. The Sensor examines the header and data portion of every network
packet, looking for patterns and behavior in the network traffic that indicate malicious activity. The
Sensor examines packets according to user-configured policies, or rule sets, which determine what
attacks to watch for, and how to respond with countermeasures if an attack is detected.
If an attack is detected, a Sensor responds according to its configured policy. Sensor can perform
many types of attack responses, including generating alerts and packet logs, resetting TCP
connections, "scrubbing" malicious packets, and even blocking attack packets entirely before they
reach the intended target.
Deployment of an NS-series Sensor
Deployment of a Sensor requires knowledge of your network to help determine the level of
configuration and the number of installed Sensors. You also need to determine the number of McAfee®
ePolicy Orchestrator® (McAfee ePO™) servers required to protect your network. The Sensor is
purpose-built for the monitoring of traffic across one or more network segments.

Before you install
About fiber-optic ports
Warnings:
•
Read the installation instructions before you connect the system to its power source.
•
To remove all power from the Sensor, unplug all power cords, including the redundant power cord.
•
Only trained and qualified personnel should be allowed to install, replace, or service this
equipment.
•
Before working on the equipment that is connected to power lines, remove all jewelry including
rings, necklaces, and watches. Metal objects will heat up when connected to power and ground,
and can cause serious burns or weld the metal object to the terminals.
•
This equipment is intended to be grounded. Ensure that the host is connected to earth ground
during normal use.
•
Do not remove the outer shell of the Sensor. Doing so will invalidate your warranty.
•
Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

chassis, contain electromagnetic interference (EMI) that might disrupt other equipment and direct
the flow of cooling air through the chassis.
•
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain
TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting
cables.
•
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in
accordance with the instruction manual, might cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which
case the users will be required to correct the interference at their own expense.
•
Refer to the Appendix for information on regulatory, compliance, and other safety requirements.
About fiber-optic ports
The Sensor uses fiber-optic connectors for its Monitoring ports. The connector type is an SFP/SFP+
fiber optic connector that is LC-duplex compatible.
Note the following:
•
Fiber-optic ports (for example, SFP/SFP+, FDDI, OC-3, OC-12, OC-48, ATM, GBIC, and 100BaseFX)
are considered Class 1 laser or Class 1 LED ports.
•
These products have been tested and found to comply with Class 1 limits of IEC 60825-1, IEC
60825-2, EN 60825-1, EN 60825-2, and 21CFR1040.
To avoid exposure to radiation, do not stare into the aperture of a fiber-optic port. Invisible radiation
could be emitted from the aperture of the port when no fiber cable is connected.
•
16
Only FDA registered, EN 60825-1 and IEC 60825-1 certified Class 1 SFP/SFP+/ laser transceivers
are acceptable for use with the Sensor.

The NS7x00 Sensors use two types of small form-factor pluggable modules as shown in the following
table. For more information, see Network Security Platform NS-series Transceiver Modules Reference
Guide.
Type
Performance
SFP
1 Gbps (copper)
1 Gbps (fiber optic)
SFP+
10 Gbps (fiber optic)
Each module is a hot-swappable input/output device that plugs into an LC-type Gigabit Ethernet port,
linking the module port with a copper or fiber-optic network. SFP optical interfaces are less than half
the size of GBIC interfaces.
To ensure compatibility, McAfee supports only those SFP and SFP+ modules purchased through McAfee
or from a McAfee-approved vendor. For a list of approved vendors, locate the relevant KnowledgeBase
article at http://mysupport.mcafee.com/Eservice/. Click Search the KnowledgeBase.
These installation instructions provide information for installing SFP and SFP+ modules that use a bail
clasp for securing the module in place in the Sensor. Your module might be slightly different. Check
the module manufacturer's installation instructions for more details. For ease of installation, insert the
module in the Sensor while it is turned off and before placing it on a rack.
To prevent eye damage, do not stare into open laser apertures.

Cable types for routers switches hubs and computers
This section lists the types of cables that you require to connect the Sensor to other network devices:
•
Use a crossover Ethernet RJ-45 cable to connect a router port to the SFP/SFP+ monitoring ports.
•
Use a straight-through Ethernet RJ-45 cable to connect a switch or a hub port to SFP/SFP+
monitoring ports.
•
Use a crossover Ethernet RJ-45 cable to connect a router port to computer to the Sensor
Management port.
•
Use a crossover Ethernet RJ-45 cable to connect a computer to the Sensor monitoring port.
Connect the cables for in-line mode
In-line Gigabit Ethernet ports can be configured as fail-open or fail-closed. The RJ-45 monitoring ports
are built-in and have a fail-open function built-in as well.
All other monitoring ports require the use of external active fail-open (AFO) kits for In-Line Fail-Open
Active configuration.
Gigabit Ethernet ports fail-close, means the flow of traffic will stop if the Sensor fails. To allow traffic to
flow uninterrupted, you must use special hardware, and cable the Sensor to external active fail-open
kits. For instructions, see the subsequent sections of this chapter.

McAfee Network Security Platform
NS7x00 Sensor Product Guide
Attaching cables to the Sensor
About connecting cables to the Monitoring ports
7
This section provides the steps to connect the Sensor's Gigabit Ethernet ports so they fail-close.
Task
1
Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports,
for example G1/1.
2
Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports,
for example G1/2.
3
Connect the other end of each cable to the network devices that you want to monitor.
For example, if you plan to monitor traffic between a switch and a router, connect the cable
connected to 1 to the router and the one connected to 2 to the switch.
Connect the cables for tap mode
To deploy the Sensor in tap mode, you must use a Sensor's Gigabit Ethernet Monitoring port pair with
a third-party external tap.
For a list of McAfee-approved third party vendors, see the KnowledgeBase at http://
mysupport.mcafee.com/Eservice/. Click Search the KnowledgeBase and locate the relevant KnowledgeBase
article.
Task
1
Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports,
for example, G1/1.
2
Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports
labeled G1/2.
3
Connect the other end of each cable to the tap.
4
Connect the network devices that you want to monitor to the tap.
Connect the cables for SPAN or hub mode
For the Sensor, monitoring in SPAN or hub mode occurs in in-line fail-open mode. When you monitor in
SPAN or hub mode, you use only single ports.
To connect an Sensor to a SPAN port or hub, plug an LC fiber-optic or 45 cable into one of the modules
and connect the other end of the cable to the SPAN port or the hub.
Connect the cables for Sensor Fail-Open
The Fail-Open Kits minimize the potential risks of in-line Sensor failure on critical network links. You
need to purchase these kits separately. Both copper and optical versions of the kit are available for the
one-gigabit ports. The standard Gigabit Fail-Open Kits and 10 Gigabit Fail-Open Kits are available for
the 1 and 10 gigabit ports respectively.
McAfee Network Security Platform
NS7x00 Sensor Product Guide

Attaching cables to the Sensor
About connecting cables to the Monitoring ports
The Monitoring ports of the Sensors can be fail-close; thus, if the Sensor is deployed in-line fail-close,
a hardware failure results in network downtime. Except the built-in RJ-45 ports which have the
fail-open function built-in as well, for the Monitoring ports to fail-open, you use the optional external
bypass switch provided in an Active Fail-Open Kit.
While the Sensor is operating, the Active Fail-Open(AFO) kit is in-line and routes all traffic directly
through the Sensor. When the Sensor fails, the switch automatically shifts to a bypass state; in-line
traffic continues to flow through the network link but is no longer routed through the Sensor. After the
Sensor resumes normal operation, the switch returns to the "inline" state, once again enabling in-line
monitoring. The port pairs with AFO kits resume inline mode after a Sensor resumes normal operation
or is in good health.
•
G0 supports passive fail-open mode with RJ-11 port control
G0 also supports active fail-open using a Copper and Fiber 1/10 Gigabit AFO kit.
•
G1 and G2 supports built-in fail-open and active fail-open mode for these interface modules:
•
4-port 10 GigE/1 GigE LR Optical with internal fail-open
•
4-port 10 GigE/1 GigE SR Optical 50 micron with internal fail-open
•
4-port 10 GigE/1 GigE SR Optical 62.5 micron with internal fail-open
•
6-port RJ-45 1 GigE with internal fail-open
All RJ-45 ports support active fail-open using only a Copper AFO kit.
•
8-port SFP/SFP+ 1/10 Gigabit
The 8-port module supports active fail-open using a Copper and Fiber 1/10 Gigabit AFO kit.
•
G3 supports both internal fail-open and active fail-open mode when connected to an Active
Fail-Open (AFO) kit
Sensor outage breaks the link connecting the devices on either side of the Sensor for a brief moment
and requires the renegotiation of the network link between the two peer devices connected to the
Sensor. Depending on the network equipment, this disruption introduced by the renegotiation of the link
layer between the two peer devices might range from a couple of seconds to more than a minute with
certain vendors' devices.
A very brief link disruption might also occur while the links between the Sensor and each of the peer
devices are renegotiated to place the Sensor back in in-line mode. This outage, again, varies depending
on the device, and can range from a few seconds to more than a minute. The performance of the
switchover from in-line to bypass and vice versa varies depending on the vendor.
You can find the installation and troubleshooting instructions for the kit in the guide that accompanies
the kit. For example, for more information on the Optical kits, see the 1 Gigabit Optical Active
Fail-Open Bypass Kit Guide and 10 Gigabit Optical Active Fail-Open Bypass Kit Guide.
Connect the cable for Sensor failover
For Sensor failover, connect two NS7x00 Sensors using the appropriate cables. These two Sensors
must be running the same software version.
Purchase a 10G SFP+ and use the proper fiber cable. Failover cables are additional hardware required
to support failover communication between two NS7x00 Sensors.
McAfee does not ship the transceiver modules and cables with the NS7x00 Sensors. Please purchase the
same separately for failover setup.
