Introducing Network Security Sensors

This section describes the McAfee® Network Security Sensors at a high-level and also describes the McAfee M-2850/M-2950 Network Security Sensor (Sensor) in detail.
Sensors are high-performance, scalable, and exible content processing appliances built for the accurate detection and prevention of intrusions, misuse, distributed denial of service (DDoS) attacks, and network access control(NAC) of hosts. When deployed at key access points, a Sensor provides real-time trac monitoring to detect malicious activity, and respond to the malicious activity as congured by the administrator.
After the Sensor is deployed and communication established, Sensors are congured and managed using the McAfee Network Security Manager (Manager) server.
The process of conguring a Sensor and establishing communication with the Manager is described in the later chapters of this guide. The Manager server is described in detail in the McAfee Network Security Platform Manager
Administration Guide.

About the M-2850/M-2950 Sensor

The M-2850/M-2950 Sensor provides eective network access control (NAC) of hosts.
®
The M-2850/M-2950 Sensor provides eective network IPS functionality as well as network access control (NAC) of hosts.
The IPS functionality involves providing real-time detection and prevention of threats and known, zero-day, or encrypted attacks. The Sensor can perform many types of attack responses, including generating alerts and packet logs, resetting TCP connections, "scrubbing" malicious packets, and blocking attack packets entirely before they reach the intended target.
NAC hosts involves regulating access to network resources based on host Operational Status level (Standard/ DHCP NAC), identity of the user logged into the host (IBAC) or both, and OOB NAC (L2, L3 ). The Sensor also provides the Hybrid NAC functionality where a host is rst subjected to DHCP-NAC and then Standard NAC at dierent ports of the same Sensor. For more information on the NAC functionality and congurations of the Manager, see McAfee® Network Security Platform NAC Administration Guide.
Throughout this guide, the terms 'Sensor' and 'M-2850/M-2950' refer to the M-2850 or the M-2950 Sensor in general.

Before you install
Working with ber-optic ports
• 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. Blank faceplates and cover panels prevent exposure to hazardous voltages and currents inside the chassis, contain electromagnetic interference (EMI) that might disrupt other equipment, and direct the ow 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, may cause harmful interference to radio communications.
• Operation of this equipment in a residential area is likely to cause harmful interference in which case users will be required to correct the interference at their own expense.
Working with ber-optic ports
The Sensor uses ber-optic connectors for its Monitoring ports. The connector type is a small form-factor pluggable (SFP) ber-optic connector that is LC-duplex compatible.
Note the following:
• Fiber-optic SFP ports are considered Class 1 laser or Class 1 LED ports.
To avoid exposure to radiation, do not stare into the aperture of a ber-optic port. Invisible radiation might be emitted from the aperture of the port when no ber cable is connected.
• Only FDA registered, EN 60825-1 and IEC 60825-1 certied Class 1 SFP laser transceivers are acceptable for use with the Sensor.

Contents
Setup overview Position the Sensor Redundant power supply Cable the Sensor Small form-factor pluggable modules Power on the Sensor Power o the Sensor

Setup overview

Setting up a Sensor involves the following steps:
Task
Positioning the Sensor.
1
Installing interface modules (SFP).
2
Attaching power, network, and monitoring cables.
3
Powering on the Sensor.
4
Conguring the Sensor after you have set up and powered on the Sensor.
5

Position the Sensor

Place the Sensor in a physically secure location, close to the switches or routers it will be monitoring. Ideally, the Sensor should be located within a standard communications rack. Each M-2850/M-2950 is a 2RU (2 rack unit). To mount the Sensor on a rack, you will attach two mounting ears and rails to the Sensor as described in the subsequent sections.

Install the rails and ears on the chassis and rack

Before you begin
Before you install the rails and ears on the chassis, make sure that power is OFF. Remove the power cable and all network interface cables from the Sensor.
McAfee® Network Security Platform M-2850/M-2950 Sensor Product Guide
17
3
Setting up the Sensor
Position the Sensor
Each rack-mounting rail and ear has holes that match up with holes in the chassis. You will need a screwdriver to secure the slotted panhead screws.
Task
Verify that you have all the parts you will need: two three-in-one rails, two chassis ears, and fourteen slotted
1
panhead screws.
Each rail includes a rail that mount to the rack, a rail that slides into the mounted rail, and a rail that is attached to the chassis.
Disassemble the slide rail by pulling the inner rail out and pushing the side latch in to separate.
2
Attach the inner rail to the chassis by fastening it with the screws provided.
3
Attach the ear to each side of the chassis.
4
Mount the L-shape and external rail to your rack frame.
5
The adjustable end of the L-shape rail is intended for placement at the back of your rack. Adjust the rail as needed for length. You are now ready to mount the Sensor in the rack.

Mount the Sensor on a rack

McAfee recommends rack-mounting your Sensors. The rack-mounting hardware included with the Sensors is suitable for most 19-inch equipment racks and telco-type racks. For maintenance purposes, you should have access to the front and rear of the Sensor.
Before you mount the Sensor on the rack, make sure that power is OFF. Remove the power cable and all network interface cables from the Sensor.
Because of the weight of the appliance, McAfee recommends that two people place the chassis into the rail cabinet.
Insert the chassis into the rail cabinet and complete the rack-mounting of the Sensor by securing the rack mount ears to two posts or mounting strips in the rack. The ears secure the Sensor to two rack posts. Be sure to fasten the ears securely to the rack.
You can also mid-mount the Sensor (optional). For details, refer to the corresponding Sensor McAfee Network
Security Platform Quick Start Guide.

Remove a Sensor from the rack

Because of the weight of the appliance, McAfee recommends that two people remove the chassis from the rail cabinet. When removing the chassis from the rack, pull chassis forward until you hear the innermost rails snap in place. On each side of the rails, press in the release button as pictured below and continue pulling the chassis.

Small form-factor pluggable modules

The Sensor uses two types of small form-factor pluggable modules as shown in the following table.
Type Performance
SFP 10/100/1000 Mbps (copper)
1 Gbps (ber 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 ber-optic network. SFP optical interfaces are less than half the size of GBIC interfaces.
To ensure compatibility, McAfee supports only those SFP modules purchased through McAfee or from a McAfee-approved vendor. For a list of approved vendors, see the on-line KnowledgeBase at http://
mysupport.mcafee.com/Eservice/. Click Search the KnowledgeBase.
These installation instructions provide information for installing an SFP module that uses a bail-clasp for securing the module in place in the Sensor. Your module may be slightly dierent. Check the module manufacturer's installation instructions for more details.
20
For ease of installation, insert the module in the Sensor while it is powered down and before placing it on a rack.
To prevent eye damage, do not stare into open laser apertures.

Cable the fail-open port

Fail-open functionality for the GE Monitoring ports is accomplished using the standard Gigabit Fail-open Bypass Kit, sold separately. McAfee recommends deploying active fail-open kits for protection of mission critical networks. Both copper and optical versions are available. For more information, see the documentation that accompanies the Kit.

Cable the Management port

The Management port is used for communication with the Manager server.
Task
Plug a Cat-5e Ethernet cable into the Management port.
1
This port is labeled as Mgmt on the front panel of the Sensor.
Connect the other end of the cable to the network device, such as a hub, a switch, or a router that in turn
2
connects to the Manager server.
To isolate and protect your management trac, McAfee strongly recommends using a separate, dedicated management subnet to interconnect the Sensors and the Manager.

Cable the Monitoring ports

Connect to the network devices you will be monitoring through the Sensor Monitoring ports. You can deploy Sensors in the following operating modes:
24

Attaching cables to the Sensor
Cable the Monitoring ports
• In-line mode (fail-closed) • SPAN or Hub mode
• In-line mode (fail-open) • Failover
• External tap mode

How to use peer ports

All full-duplex Sensor deployment modes require the use of two peer monitoring ports on the Sensor. On the Sensors, the numbered ports are wired in pairs to accommodate the trac.
The following SFP Gigabit Ethernet ports are coupled and must be used together:
Port Pairs Transceiver Type
1A and 1B SFP
2A and 2B SFP
3A and 3B SFP
4A and 4B SFP
5A and 5B SFP
6A and 6B SFP
4
• You cannot congure, for example, 1A and 2A to work together as a pair.
• Since monitoring ports are internally wired, when you disable one of the ports in a pair, the corresponding port is also disabled.
Figure 4-1 Using peer ports

Default Monitoring port speed settings

Be sure that the switch/router ports connected to the Sensor Monitoring ports match the Sensor

Attaching cables to the Sensor

Cable for in-line

• Use a crossover Ethernet RJ-45 cable to connect a router port to the 10/100/1000 copper SFP Monitoring ports.
• Use a straight-through Ethernet RJ-45 cable to connect a switch/hub port to 10/100/1000 copper SFP Monitoring ports.
• Use a crossover Ethernet RJ-45 cable to connect a router port to PC to the Sensor Management port.
Cable for in-line
The Gigabit Ethernet ports fail-close, meaning they stop the ow of trac if the Sensor fails. To allow trac to ow uninterrupted, you must use special hardware and cable the Sensor for fail-open functionality. For
instructions, see the section later in this chapter.
This section provides the steps to connect the Sensor's Gigabit Ethernet ports so they fail-close.
Task
Plug the cable appropriate for use with your Gigabit Ethernet into one of the Monitoring ports, for example,
1
1A.
You should also use a crossover Ethernet RJ-45 cable to connect a PC to the Sensor monitoring port.
Plug another cable into the peer of the port used in Step 1.
2
Connect the other end of each cable to the network devices that you want to monitor.
3
For example, if you plan to monitor trac between a switch and a router, connect the cable connected to 1A to the switch and the one connected to 1B to the router.

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 the link Search the KnowledgeBase and locate the relevant KnowledgeBase article.
Task
Plug the cable appropriate for use with your Gigabit Ethernet into one of the Monitoring ports, for example,
1
1A.
Plug another cable into the peer of the port used in Step 1.
2
26
Connect the other end of each cable to the tap.
3
Connect the network devices that you want to monitor to the tap.

McAfee® Network Security Platform M-2850/M-2950 Sensor Product Guide

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 ber-optic or 45 cable into one of the modules and connect the other end of the cable to the SPAN port or the hub.

Cable the fail-over interconnection

Before you begin
To enable fail-over communication between two M-2850/M-2950 Sensors, you will require ber or copper SFPs and an LC-LC or RJ45-RJ45 cable as a fail-over cable.
Fail-over requires connecting two identical M-2850/M-2950 Sensors (same model, same software) using an interconnection cable or cables. Gigabit port 6A is the fail-over interconnection port on the M-2850/M-2950 Sensors.

About the fail-open hardware

The standard Gigabit Fail-Open Kit (sold separately) minimizes the potential risks of in-line Sensor failure on critical network links. Both copper and optical versions of the Kit are available for 1 Gigabit ports.
The Monitoring ports on M-2850/M-2950 fail-close; thus, if the Sensor is deployed in-line, a hardware failure results in network downtime. Fail-open operation for the Monitoring ports requires the use of the optional external Bypass Switch provided in the Kit.

Attaching cables to the Sensor
About the fail-open hardware
With the Bypass Switch in place, normal Sensor operation supplies power to the switch through a control cable. While the Sensor is operating, the switch is "on" and routes all trac directly through the Sensor. When the Sensor fails, the switch automatically shifts to a bypass state: in-line trac continues to ow through the network link, but is no longer routed through the Sensor. Once the Sensor resumes normal operation, the switch returns to the "on" state, once again enabling in-line monitoring.
Note that 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 may range from a couple of seconds to more than a minute with certain vendors' devices.
A very brief link disruption may 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.
Installation and troubleshooting instructions for the Kit can be found in the Guide that accompanies the kit. For example, for more information on the Optical kit, see the standard Gigabit Optical Fail-Open Bypass Kit Guide.
