NX SERIES / 2019

CHAPTER 1: The NX 5500

The FireEye NX 5500 stops the new generation of cyber attacks that use zero-day Web exploits and multiprotocol malware callbacks to compromise the majority of today's networks.

When used as a standard (or integrated) appliance, the NX Series appliance performs both monitoring and analysis functions. When used as a sensor within the FireEye Network Security, the NX 5500 only monitors traffic, extracting objects and URLs and sending them to an MVX cluster for analysis. This allows a flexible approach to your security solution.

For information about using the NX Series appliance as a sensor, see the User Guide for your software release.

Inline Deployment

CHAPTER 2: Deployment

There are two types of deployment: inline and out-of-band. An inline deployment provides high security by blocking all malicious traffic from reaching your network. An out-of-band deployment only monitors malicious content as it enters your network; it does not block malicious content.

FireEye strongly recommends using an inline deployment mode.

Deployment modes include:

• Inline Deployment below

• Inline Proxy Deployment on the next page

• Test Access Point (TAP) Deployment on page 12

• Port Mirroring (SPAN) Deployment on page 13

Inline Deployment

The diagram below illustrates the deployment of an NX 5500 appliance installed between the LAN and the firewall in a typical network topology.

Prerequisites

Before connecting the NX 5500 appliance to your network:

© 2019 FireEye

NX Series Hardware Administration GuideCHAPTER 2: Deployment

• Make sure that the connecting routers or switches do not provide data output greater than 1 Gbps for RJ45 ports and 10 Gbps for SFP+ ports.

• Determine which ports on your routers or switches provide ingress and egress data

Cabling

Connect the appropriate cables to the NX 5500 appliance’s ports as follows:

• ether1: Connect one end of the cable to the NX 5500 appliance’s ether1 port, and connect the other end to your LAN-facing switch. This will enable you to access the appliance’s Web UI.

• pether3: Connect one end of the cable to the NX 5500 appliance’s pether3 port, and connect the other end to your LAN-facing switch.

• pether4: Connect one end of the cable to the NX 5500 appliance’s pether4 port, and connect the other end to the Internet-facing switch.

You can monitor another network segment by connecting a LAN-facing switch and an Internet-facing switch to pether5–6.

Alternatively, pether4—14 can be used instead.

Inline Proxy Deployment

The diagram below illustrates the deployment of an NX 5500 appliance installed between the LAN and the firewall in a typical network topology.

If your environment contains Web proxies or other NAT devices that obscure incoming IP addresses, deploy the NX device so that it sees Web traffic from the internal (or LAN) side of the proxy. If you place the NX device on the external side of the proxy, the NX appliance reports a malicious site as being the LAN IP of the proxy.

11© 2019 FireEye

Test Access Point (TAP) Deployment

Connect your NX 5500 appliance between two routers or switches on your network, and to your proxy.

Prerequisites

Before connecting the NX 5500 appliance to your network:

• Make sure that the connecting routers or switches do not provide data output greater than 1 Gbps for RJ45 ports and 10 Gbps for SFP+ ports.

• Determine which ports on your routers or switches provide ingress and egress data.

Cabling

Connect the appropriate cables to the NX 5500 appliance’s ports as follows:

• ether1 cable: Connect one end of the cable to the NX 5500 appliance’s ether1 port, and connect the other end to your LAN-facing switch. This will enable you to access the appliance’s Web UI.

• pether3 cable: Connect one end of the cable to the NX 5500 appliance’s pether3 port, and connect the other end to the LAN-facing switch.

• pether4 cable: Connect one end of the cable to the NX 5500 appliance’s pether4 port, and connect the other end to the proxy server.

• pether5 cable: Connect one end of the cable to the NX 5500 appliance’s pether5 port, and connect the other end to the LAN-facing switch.

You can monitor additional proxy servers by connecting additional proxies and LAN-facing switches to pether6—14.

Test Access Point (TAP) Deployment

Test Access Point (TAP) uses a TAP device to provide a real-time duplicate copy of the network traffic through the network.

Test Access Points have the following limitations:

• You must purchase a separate TAP device to deliver packets to the NX Series device.

• A TAP deployment does not block malware from accessing your network.

To deploy the FireEye NX Series appliance using a TAP device, you first connect the TAP device inline to your network. You then connect the FireEye NX Series monitoring ports to the ingress and egress ports on the TAP device. The following diagram illustrates the TAP deployment in a typical network topology.

Prerequisites

Before connecting the NX 5500 appliance to your network:

• Make sure that the connecting routers or switches do not provide data output greater than 1 Gbps for RJ45 ports and 10 Gbps for SFP+ ports.

• Determine which ports on your routers or switches provide ingress and egress data

Cabling

Connect the appropriate cables to the NX 5500 appliance’s ports as follows:

• ether1: Connect one end of the cable to the NX 5500 appliance’s ether1 port, and connect the other end to your LAN-facing switch. This will enable you to access the appliance’s Web UI.

• pether3: Connect one end of the cable to the NX 5500 appliance’s pether3 port, and connect the other end to your TAP device.

Port Mirroring (SPAN) Deployment

Port mirroring deployment, also known as Switch Port Analyzer (SPAN) packet capture, is usually the least expensive option in a low-traffic network environment. To set up port mirroring, you configure a router or switch with port mirroring capability to forward a copy of incoming and outgoing traffic passing between selected ports to SPAN ports on the switch. Then connect the SPAN ports to the appliance.

Port mirroring has the following limitations:

• Heavily used networks may result in dropped packets that are not passed to the NX Series appliance.

© 2019 FireEye

Port Mirroring (SPAN) Deployment

• Port mirroring is active packet duplication. The router or switch uses its processing power to mirror the network packets and pass these packets to the NX Series device. In a heavily used network, the network quality and response times tend to degrade.

• The router or switch must be configured to provide port-mirrored data to the NX Series appliance. Maintenance costs for this configuration can be higher than other configurations.

• Detected malware cannot be prevented from accessing your network.

• SPAN port connectivity issues may cause delays in your deployment. You may need to add a few days to troubleshoot the connectivity issues.

The following diagram illustrates the port mirroring deployment in a typical network topology.

Prerequisites

Before connecting the NX 5500 appliance to your network:

• Make sure that the connecting routers or switches do not provide data output greater than 1 Gbps for RJ45 ports and 10 Gbps for SFP+ ports.
