Network TAP vs SPAN Port: Putting Them to the Test

Posted by Chris Greer on 4/27/17 8:08 AM

For years now we all have read about the difference between data capture off a span/mirror port and an inline network TAP. In fact, many of those comments have come from one of the great moderators of lovemytool.com, Tim O'Neill, the @OldCommGuy who loves the TAP side of the ring.

Packet Pioneer was interested to see the difference between a data stream captured on a network TAP versus a SPAN port. So they set up a test with a few PCs, a TAP, a SPAN port, a couple of hardware network analyzers, and a healthy stream of data.

The results were interesting, to say the least: The study showed that Tim O’Neill is correct!

How to Choose the Right Cables for Your Industrial Ethernet

Posted by Patrick Nixdorf on 4/6/17 8:00 AM

It’s easy to get ahead of ourselves when we talk about the Industrial Ethernet. You look at the ever-growing reality of the Industrial Internet of Things and the longstanding concerns for security in these networks and you start to take this level of connectivity for granted.

However, so many companies are only just starting their Industrial Ethernet journeys. As you upgrade your network, choosing the right cabling will be critical to ensure you don’t disrupt traffic in the process.

Choosing cables for standard office settings can be hard enough—but when you’re upgrading to Ethernet in an industrial setting, keep these 6 points in mind.

The 101 Series: Bypass Network TAPs Keepers of the Critical Link

Posted by George Bouchard on 3/28/17 8:00 AM

There are some great network tools on the market that provide protection for your organization's operations on the Internet. The problem with using them is that they can do the unthinkable by introducing a potential “point of failure” when inserted directly into the path of the Critical Link.

The Bypass TAP was developed specifically to resolve the problem of an in band security appliance causing a “point of failure”.

It’s Not Wiretapping—It’s Network Tapping

Posted by Randy Clark on 3/23/17 8:00 AM

We all know those old mobster movies, right? Where the cops are tapping phone lines to take down America’s most wanted criminals.

Or if you need a more recent example, you can think of all of the surveillance involved in HBO’s The Wire. And then there’s the current social chatter around surveillance that we don’t have to get into.

For 40 years, we’ve labeled all of these situations with the same word—wiretapping. But words matter and it’s time to get ourselves out of the 1970s.

Today, it’s not wiretapping—it’s network tapping.

[Infographic] Are You Monitoring a 1G, 10G, 40G or 100G Network?

Posted by Chris Bihary on 3/21/17 8:00 AM

What tools are you deploying in your network?

Are you monitoring out-of-band with tools like Wireshark, forensics, Intrusion Detection Systems, Security Information and Event Management or Application Performance Monitoring?

Monitoring today's network speeds of 1G/10G/40G/100G requires 100% packet capture to ensure the tool(s) have all the data it need to perform it's job.

Follow your network path in this new interactive infographic and pick which tool you are using and then see which network TAP will work best for your solution.
