Introducing Network Security Sensors
This section describes the McAfee
®
Network Security Sensors at a high-level and also describes the
McAfee
®
M-2750 Network Security Sensor (Sensor) in detail.
Sensors are high-performance, scalable, and flexible 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 traffic monitoring to detect malicious activity, and respond to the malicious activity as
configured by the administrator.
After the Sensor is deployed and communication established, Sensors are configured and managed
using the McAfee Network Security Manager (Manager) server.
The process of configuring 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-2750 Sensor
The M-2750 Sensor provides effective network access control (NAC) of hosts.
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 first subjected to
DHCP-NAC and then Standard NAC at different ports of the same Sensor. For more information on the
NAC functionality and configurations of the Manager, see McAfee
®
Network Security Platform NAC
Administration Guide.
Throughout this guide, the terms 'Sensor' and 'M-2750' refer to the M-2750 Sensor in general.
M-2750 physical description
The high-port density M-2750 Sensor, designed for high bandwidth links, is equipped with twenty Fast
Ethernet ports (or interfaces). This Sensor can monitor ten 1 Gbps Ethernet segments in full-duplex
mode (tap or in-line), and twenty segments in half-duplex mode (monitoring SPAN ports or hubs). An
M-2750 can monitor upto 600 Mbps of aggregate traffic.
