Monitorama has posted the videos from their conference PDX 2014 and I’ve been watching them during concentration breaks. Most of them are very good story telling from real practitioners who have real world experiences. I wanted to call out just two that impressed me deeply. Noah Kantrowitz’s session from Monitorama PDX 2014 talks about using […]

Cisco Live 2014 is right around the corner! It’s almost time to start packing. The other day, Keith Miller (@packetologist), a first-time Cisco Live attendee, asked me on Twitter:
@BobMcCouch Since you are the king of being prepared, what is your travel pack consisting of to CLUS?

I have a bit of a reputation among some of my consulting clients as being ready for just about anything. Normally, that means my laptop bag weighs about 50 lbs. But for Cisco Live, I choose to travel light. I’ve seen people in the airport on the way to, and from, the event with a LOT of stuff. Sure, some folks are presenters or carrying company stuff but for the rest, you probably just have too much stuff.
Why choose to travel as light as possible? Here are just a few reasons:
Network visibility is difficult design problem. After years of research and customer engagements, Ive been able to prove that network visibility can be reduced to two states. I present the results in this chart.

Integrating Route Explorer with the OpenDaylight Controller for SDN Provisioning
Despite the hype surrounding SDN, no one can afford to leap frog to the new technology. They must have a strategy to integrate the new with the old to reap the biggest benefits. Packet Design has taken its first step in helping customers do so. We’ve integrated Route Explorer with the OpenDaylight controller to automate SDN provisioning of RSVP-TE tunnels. For network engineers, this means eliminating the manual process of creating tunnels. They can simply plan it in Route Explorer and have the OpenDaylight controller automatically provision it. Some of our early adopter customers – especially service providers – are very happy about this.
OpenDaylight only supports TE tunnels today, but our integration is an example of how we can support SDN in hybrid environments. Our analytics technology is unique because it allows us to build SDN conforming applications in the presence of non-conforming applications. You don’t have to do a forklift hardware upgrade in the network or build a brand new network architecture where the controller provisions everything. We are able to demonstrate provisioning of RSVP-TE tunnels in hybrid environments Continue reading
Last week I attended the Open Networking User Group conference. My main reason for attending was to participate in three roundtable discussions put on by Tech Field Day. These sessions were recorded, and I’ll be following up with specific thoughts on each session in later blog posts.
These round-tables only occupied a portion of the two-day conference, so I spent the remainder of the time speaking with some of the vendors and sitting in a few of the sessions.
I wasn’t permitted to attend a large chunk of ONUG sessions, and I’ll get to that in the next paragraph. I did manage to see a good friend Kyle Mestery present on two of my favorite topics – OpenDaylight and OpenStack. The sessions at ONUG were not recorded, but I’ll again direct you to this video for a reasonably close approximation:
Kyle is the embodiment of the passion and energy found in great communities like OpenStack and OpenDaylight, and if you ever have the opportunity to hear him present, I encourage you to take it.
I also finally got to meet Brad Hedlund in meatspace:

Point of Sale systems that process debit and credit cards are still being attacked with an increasing variety of malware. Over the last several years PoS attack campaigns have evolved from opportunistic attacks involving crude theft of card data with no centralized Command & Control, through memory scraping PoS botnets with centralized C&C and most recently to highly targeted attacks that require a substantial amount of lateral movement and custom malware created to blend in with the target organization.
While contemporary PoS attackers are still successful in using older tools and methodologies that continue to bring results due to poor security, the more ambitious threat actors have moved rapidly, penetrating organizational defenses with targeted attack campaigns. Considering the substantial compromise lifespans within organizations that have active security teams and managed infrastructure, indicators shared herein will be useful to detect active as well as historical compromise.
Organizations of all sizes are encouraged to seriously consider a significant security review of any PoS deployment infrastructure to detect existing compromises as well as to strengthen defenses against an adversary that continues to proliferate and expand attack capabilities.
In addition to recent publications discussing Dexter and Project Hook malware activity, Arbor ASERT is currently Continue reading
Company ABC has multiple buildings and two internet connections via 2 different ISPs. Both BR-B and BR-C receive a default route via eBGP from the ISPs and they inject it in OSPF. For some reason, when ISP-1 link goes down, entire Building-A looses the internet access ! Something must be wrong...
