Network Tap Devices

Our real-time malware scanning engine digs through network packets to identify the latest (zero-day) malware threats.  The use of a network tap provides the critical interface between the NACwall appliance and network infrastructure.  A network tap is a hardware device which provides a way to access the data flowing across a computer network. In many cases, it is desirable for a third party to monitor the traffic between two points in the network. If the network between points A and B consists of a physical cable, a “network tap” may be the best way to accomplish this monitoring. The network tap has (at least) three ports: an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic through unimpeded, but also copies that same data to its monitor port, enabling a third party to listen.

Network taps are commonly used for network intrusion detection and prevention systems, packet sniffers, and other monitoring and collection devices and software that require access to a network segment. Taps are used in security applications because they are non-obtrusive, are not detectable on the network (having no physical or logical address), taps can deal with full-duplex and non-shared networks, and will usually pass-through traffic even if the tap stops working or loses power.

We’ve scoured the globe and have internally tested numerous nTap devices for their ease of use and performance on 10/100/1G network environments in conjunction with the NACwall NG appliance family.

In particular, an nTap is highly recommended by NetClarity for use on the Eth1 connection of the NACwall NG appliance when running our zero-day malware detection and quarantine system.

Only a few have made the cut.  The following nTap tools are approved by NetClarity, Inc. for use in conjunction with NACwall 2G appliances, for their ability to smoothly tap and buffer network traffic in real-time.BlackBox-nTap
