Historical Lookback - The Proof is in the Packet

Posted by Chris Bihary on 6/22/17 8:00 AM

"It's the Unicorn we've been looking for!"

This was the response I got the other day when I was explaining to a customer the benefits of looking back at packets before and after they pass through an active, inline device and a packet capture or forensics tool.

Simply put, how else will enterprise networks have real-time knowledge of an attempted attack, as well as the ability to look back and see how the packets were altered or dropped?

Historical lookback aka before & after, is solution that uses hybrid bypass TAPs with monitoring ports that allow both security tools, such as next-gen firewalls and intrusion prevention systems to share packets with multiple monitoring tools such as network packet capture, forensics, deep packet inspection, etc.

MTP® Brand Connectors versus Generic MPO in Fiber Networks

Posted by Patrick Nixdorf on 6/15/17 8:00 AM

Generic MPO connectors have been the standard for network architects who require density and strive for shorter install times, as well as simplified cabling infrastructure for their 40G/100G data centers. Multi-mode MPO connectors can pack 12, 24, or 72 fibers into one ferrule, this increased density has bolstered its appeal, especially in the space-restricted data center market.

However, in higher fiber count MPO connectors, an additional loss penalty has come to be expected due to the difficulty in achieving physical contact across all of the fibers.

Learn how US Conec's MTP® brand connectors boast the lowest dB loss...

[New Product] Garland Introduces Scalable Visibility with Passive Fiber Modular Chassis up to 100G

Posted by Chris Bihary on 5/18/17 9:00 AM

“How do you scale your network infrastructure to support multiple monitoring tools (at varying network speeds) without adding additional infrastructure - while still ensuring data quality?”

This is the problem we have been hearing in the last few years. Data centers (D1 & D2) and enterprise networks have many challenges and two of the big ones are providing the IT department anytime access to full-duplex traffic, while guaranteeing full packet capture. Now layer on top of that a stack of 1G legacy monitoring tools in addition to the migration to 10G/40G and 100G speeds.

To this problem, we introduce a solution:
Garland Technology’s new Passive Fiber Modular Chassis.

A flexible, scalable and affordable high density solution for managing up to 24 links in a 1U box at network speeds of 1G/10G/40G/100G.

[Video] VLAN Analysis with Wireshark 2.0

Posted by Tony Fortunato on 5/16/17 8:00 AM

When I teach Wireshark classes, I commonly get asked, “What do I do when I get back to my desk?”, “What if I can’t span a port, or don’t have a TAP?”

I typically show my attendees dozens of “Baselines” that would only take a few minutes to complete.

Here’s an example of one of my favorite baselines; Start a capture and analyze whatever you see. No taps, span or mirror ports.

[Video] How To Determine DHCP Option 60 Value Using Wireshark

Posted by Tony Fortunato on 4/11/17 8:00 AM

There are an increasing number of network attached devices, and trying to keep them organized gets to be challenging. Since different devices might require different IP configuration settings and statically configuring them isn’t realistic.

There are several approaches to deal with this.

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.
