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”.

The 101 Series: Filtering TAPs

Posted by George Bouchard on 3/14/17 8:00 AM

In our 101 network TAP series, we have explained the functionality of the various network TAPs that are available to gain access to the traffic that is typically found in a network. We have reviewed passive fiber TAPs, copper network TAPs, aggregation TAPs, SPAN/regeneration TAPs and the bypass TAP.  

Now we have a new 1U or 2U Chassis System that supports our filtering TAPs – which for you, means an affordable 1G Packet Broker System that can do it all in one box. 

Read on to see what filtering can do for your network…

The 101 Series: Why Do We Need an Aggregating Network TAP?

Posted by George Bouchard on 2/28/17 8:30 AM

If you remember in my post on Breakout TAPs, there was a small problem when your network analyzer or monitoring device only had one network interface card (NIC). You could only look at the traffic going from ports A to B or the traffic going from ports B to A, but not at both streams of network traffic at the same time. Also, a breakout TAP can only send network traffic to a single analyzer or monitoring device.

Now, breakout network TAPs are still a great solution for many situations, but nevertheless, engineers love solving problems – so they set out add more functionality by developing the Aggregating TAP.

The 101 Series: A Primer On Network TAPs

Posted by George Bouchard on 1/31/17 8:00 AM

When the subject of Test Access Points or Traffic Access Point (most commonly referred to as a network TAP) comes up, the image that may come up in people’s mind is a device that taps into the network to allow a copy of the traffic to be sent to an analyzer.  

And, on a very basic level this is true. So many people dismiss TAPs as simple ways to gain access to their network traffic for analysis.

The truth is, the subjects of network TAPs is quite complex, read on to learn about the six different network TAP designs.

What Is A Network TAP, Anyway?

Posted by George Bouchard on 1/27/17 9:00 AM

Despite being in the technology industry, there are some things system security pros (or their bosses) just aren't familiar with.

One of the questions we get at Garland is, "What is a network TAP, anyway?"

The next question is typically, "And why do I need one?"

Here's a good overview of network TAPs.

The 101 Series: Quick Connect Tips for Out-of-Band Monitoring Appliances

Posted by George Bouchard on 11/15/16 10:25 AM

Active in-line appliances are on the front-lines of your network, but out-of-band monitoring devices are just as important to your overall network visibility and security. Your out-of-band monitoring devices might include application performance monitoring, Wireshark, network analyzers, lawful intercept and deep packet inspection.

In this post, we’ll discuss the keys to ensuring 100% network access for your out-of-band monitoring appliances that analyze your network traffic.
