H A P T E R Overview This chapter provides an introduction to IntruShield sensors. About IntruShield sensors IntruShield sensors are high-performance, scalable, and flexible content processing appliances built for the accurate detection and prevention of intrusions, misuse, and distributed denial of service (DDoS) attacks. IntruShield 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.
McAfee® IntruShield® IPS 4.1 Overview M-6050 Sensor Product Guide M-6050 key features The IntruShield sensor is purpose-built for the monitoring of traffic across one or more network segments. For more information on IntruShield, see the Getting Started Guide Following is an example of a network topology using Gigabit Ethernet throughput. In the illustration, IntruShield provides IPS and Alert Viewer protection to outsourced servers.

Power Supply B swappable, redundant power supply. This power supply also uses a standard IEC320-C13 port, and you can use the McAfee-provided cable or acquire one that meets your specific needs. The M-6050 does not have internal taps; it must be used with a third-party external tap to run in tapped mode.

McAfee® IntruShield® IPS 4.1 Before You Install M-6050 Sensor Product Guide Unpacking the sensor Unpacking the sensor To unpack the sensor: Place the sensor box as close to the installation site as possible. Position the box with the text upright.
H A P T E R Setting up an M-6050 This chapter describes the process of setting up a sensor to prepare it for configuration. Setup Overview Setting up a sensor involves the following steps: Positioning the sensor. (See below.) Installing interface modules (SFP and XFP).
Before you mount the sensor in the rack, make sure that power is OFF. Caution: Remove the power cable and all network interface cables from the sensor Because of the weight of the appliance, McAfee recommends that two people Note: place the chassis into the rail cabinet.
Slide in the power supply until it makes contact with the backplane, then push firmly to mate the connectors solidly with the backplane. For true redundant operation with the optional redundant power supply, Note: McAfee recommends that you plug each supply into a different power circuit. For optimal protection, use uninterruptable power sources.
SFP optical interfaces are less than half the size of GBIC interfaces. To ensure compatibility, McAfee supports only those SFP and XFP modules Note: purchased through McAfee or from a McAfee-approved vendor. For a list of approved vendors, see the on-line KnowledgeBase, https://support.mcafee.com. https://mysupport.mcafee.com These installation instructions provide information for installing an SFP and an XFP module that uses a bail clasp for securing the module in place in the sensor.

The M-6050 sensor has no power switch. The sensor powers on as soon as one of its power cables is connected to a power source. Powering off the sensor McAfee recommends that you use the shutdown CLI command to halt the sensor before powering it down. For more information on CLI commands, see Sensor...
Follow the steps outlined in this chapter to connect cables to the various ports on your sensor. Cabling the Console port The Console port is used for setup and configuration of the sensor. For console connections, plug the DB9 Console cable supplied by McAfee into Console port (labeled Console on the sensor front panel).

Connect the other end of the cable to the network device (for example, hub, switch, router) that in turn connects to the Manager server. To isolate and protect your management traffic, McAfee strongly Note: recommends using a separate, dedicated management subnet to interconnect the sensors and the Manager.
McAfee® IntruShield® IPS 4.1 Attaching Cables to the M-6050 M-6050 Sensor Product Guide Cabling for in-line You cannot configure, for example, IA and 2A to work together as a pair. Note: Figure 9: Port pair Default monitoring port speed settings Be sure that the switch/router ports connected to the sensor Monitoring ports match the sensor configuration.
McAfee® IntruShield® IPS 4.1 Attaching Cables to the M-6050 M-6050 Sensor Product Guide Cabling for TAP mode Plug the cable appropriate for use with your Gigabit Ethernet into one of the ports labeled xA (for example, 1A). Plug another cable into the peer of the port used in Step 1. This port will be labeled xB (for example, 1B).
McAfee® IntruShield® IPS 4.1 Attaching Cables to the M-6050 M-6050 Sensor Product Guide Using Fail-Open hardware To connect two M-6050s for failover: Plug the cable appropriate for use with your XFP module into port 4A of the active sensor. Connect the other end of the cable to port 4A of the standby sensor.
