Reflections from the Global Commission on the Stability of Cyberspace

Two weeks ago, a small delegation from the Internet Society was in Delhi for a series of meetings. (See yesterday’s post about GCCS and GFCE.) In this post, I’ll pick up with the Global Commission on the Stability of Cyberspace (GCSC).

The international community has been trying to develop cybernorms for international behaviour for over a decade. This has been happening through UN processes, through the GCCS, through international law discourse, and other fora. And, some progress has been made. For instance, the Tallin manuals provide some insights on how international law applies to cyber war and cyber operations, while the UN GGE, among others, recognized the applicability of international law on the digital space and has provided some protection to cybersecurity incident response teams (CIRTs) and critical infrastructure.

However, these processes are slow, and certainly not without roadblocks. The 5th UN Group of Governmental Experts on Information Security (GGE), for example, failed to reach consensus on whether certain aspects of international law, in particular the right to self-defence, apply to cyberspace as well as issues related to attribution. During a panel at GCCS, five participants in the 5th UN GGE shared their perspectives. To me Continue reading

Fish Gets a New Job: “Solutions Architect”

Many of the best things that have happened in my life weren’t planned.  ?  Becoming a “Solutions Architect” is one of those things.  I didn’t plan it.  I’ve been in CPOC (Customer Proof of Concept) for almost 17 years now.  ?  Why?  Cause truthfully, having fun and enjoying my job is exceedingly important to me.  And I’ve never seen a job (in Cisco or outside) that would be more of an absolute perfect fit for me and what I consider “fun”.

But like I said…. Many of the best things that have happened in my life weren’t planned.  ?

For those of you who know how very much I totally love CPOC… you might be wondering “Fish, what happened that made you decide to look for another job?”.    Uh… nothing.  Like I said… it wasn’t planned.  In fact, i didn’t even interview or apply for the job.

The new job is actually

  • a newly created position in a
  • just created team
  • reporting to an awesome leader
  • with 2 technical playmates I adore (ahem.. sorry.. co-workers)

Popular Destinations rerouted to Russia

Early this morning (UTC) our systems detected a suspicious event where many prefixes for high profile destinations were being announced by an unused Russian Autonomous System.

Starting at 04:43 (UTC) 80 prefixes normally announced by organizations such Google, Apple, Facebook, Microsoft, Twitch, NTT Communications and Riot Games were now detected in the global BGP routing tables with an Origin AS of 39523 (DV-LINK-AS), out of Russia.

Looking at timeline we can see two event windows of about three minutes each. The first one started at 04:43 UTC and ended at around 04:46 UTC. The second event started 07:07 UTC and finished at 07:10 UTC.

Even though these events were relatively short lived, they were significant because it was picked up by a large number of peers and because of several new more specific prefixes that are not normally seen on the Internet. So let’s dig a little deeper.

One of the interesting things about this incident is the prefixes that were affected are all network prefixes for well known and high traffic internet organizations. The other odd thing is that the Origin AS 39523 (DV-LINK-AS) hasn’t been seen announcing any prefixes for many years (with one exception below), so why Continue reading

VMware Closes Acquisition of VeloCloud Networks

As applications and data continue to be distributed more broadly from the data center to the edge, customers are increasingly relying on software-defined wide-area networks (SD-WANs) versus traditional networking for flexible, secure connectivity.  It’s for this reason that I am pleased to share that we officially closed our acquisition of VeloCloud Networks today, bringing their industry-leading, cloud-delivered SD-WAN solution to our growing software-based networking portfolio. The acquisition of VeloCloud significantly advances our strategy of enabling customers to run, manage, connect and secure any application on any cloud to any device.

VMware NSX was a game changer in the industry, and it has become the industry-leading implementation of network virtualization. Customers choose NSX because it delivers network and security services closest to the application. By adding VeloCloud’s SD-WAN solutions to our portfolio, we are extending our value in the enterprise and increasing our relevance with service providers by offering end-to-end automation, application continuity and security from data center to cloud edge. VeloCloud will bring the same properties to the wide-area network with an SD-WAN solution that provides full visibility, metrics, control and automation of all endpoints, resulting in better performance and availability for enterprise and cloud applications.

Battle For Datacenter Compute: Qualcomm Centriq Versus Intel Xeon

Putting more and more cores on a single CPU and then having two CPUs in a standard workhorse server is something that yields the best price/performance for certain kinds of compute-hungry workloads, and these days, particularly those who want top bin Xeon parts and the cost of the processor is no object because it saves on the total number of server nodes that has to be deployed.

But this is not the only way to pack the most compute density into a rack. A case can be made for middle bin parts, particularly for workloads that scale well across many …

One Little Thing Can Break All Your Automation

I’ve been doing some work automating A10 Networks load balancers recently, and while testing I discovered a bug which broke my scripts. As hard as I try to code my scripts to cope with both success and failure, I realized that the one thing I can’t do much with is a failure of a key protocol.

Breaking Badly

So what matters when I’m automating device configurations? Three things come to mind immediately:

The Network / Transport

I need reliable network connectivity, or my automation requests will constantly be timing out or failing. While a script should be able to cope with an occasional network failure, unreliable networks are not fun to work with.

Data Transfer Format

Pick a format (XML, JSON) and use it consistently. I’m happy so long as I can send a request and read a response in a given format. If I send a request using JSON, send a response using JSON. Funnily enough I was troubleshooting WordPress xmlrpc recently and noticed that when there was an error, the XML command being issued received a 404 error followed by, well, you’d hope an XML error response, right? No, because it was an HTTP 404 error, the site Continue reading

Let’s Mobilize for Better Data Stewardship

If we want organizations like Equifax to be good data stewards, we, the users and consumers, must mobilize.

In October, the Internet Society explored why the dominant approach to data handling, based around the concepts of risk and compliance, does not work. To recap: “…data handlers try to adhere to regulatory requirements and minimize the risk to themselves – not necessarily to the individuals whose data they handle. For some data handlers, the risk that poor security creates may not extend to them.”

Euphemistically put, Equifax has not been an example of forthcomingness, transparency, and accountability. Users can change this paradigm. Users can shift the cost of a data breach onto the data handler by holding the accountable for their action or lack of action.

The key is to organize. For example, Consumer Reports is organizing a campaign calling on Equifax to take the next steps to address the fallout from the data breach. Their first step was to deliver a petition signed by over 180,000 individuals to Equifax’s headquarters.

The Internet Society just pledged $10k to this cause, to help Consumer Reports make sure Equifax does everything in its power to make things right for consumers in Continue reading

Top benefits of using Linux in the modern enterprise

Let’s be honest. There are many enterprise data centers (and data center admins) who aren’t crazy about Linux. But most of that opposition comes from simply not understanding the benefits of Linux and not experiencing Linux hands-on. Fortunately, we’ve got a comprehensive guide to everything Linux that you can use to get familiar with the basics. Once you start testing out Linux for yourself and getting comfortable with it, I think you’ll find that Linux is the best operating system available today.

So what are the benefits, in general, of using Linux? Some of these benefits include:

  • Consistent operating model. No matter what version or distribution of Linux you use, whether you’re on a supercomputer or a tiny embedded device, the general operation of Linux is the same no matter where you go. What this means is that, with some exceptions, the command line syntax is similar, process management is similar, basic network administration is similar, and applications can be (relatively) easily ported between distributions. The end result of this consistent operating model is a cost savings generated by greater staff efficiency and flexibility.
  • Scalability. Linux is eminently scalable and is able to run on everything from wristwatches to supercomputers Continue reading

GENCI: Advancing HPC in France and Across Europe

One of the more significant efforts in Europe to address the challenges of the convergence of high performance computing (HPC), high performance data analytics (HPDA) and soon artificial intelligence (AI), and ensure that researchers are equipped and familiar with the latest technology, is happening in France at GENCI (Grand équipement national de calcul intensif).

Grand équipement national de calcul intensif (GENCI) is a “civil company” (société civile) under French law and 49% owned by the State, represented by the French Ministry of Higher Education, Research and Innovation (MESRI), 20% by the Commissariat à l’Energie Atomique et aux énergies alternatives ( …
